Google Embed API format data before calling .execute() - google-analytics

I need to format the response I get from Analytics before showing it inside a Google Chart, I tried editing the response when the on("success"... method gets fired but I found that it gets called after the .execute().
Is there any way to edit the response after receiving it and before it populates the chart?
This is my function:
var dataChart5 = new gapi.analytics.googleCharts.DataChart({
reportType: 'ga',
query: {
'ids': 'ga:***', // My ID
'start-date': '31daysAgo',
'end-date': 'yesterday',
'metrics': 'ga:users,ga:percentNewSessions,ga:sessions,ga:bounceRate,ga:avgSessionDuration,ga:pageviews,ga:pageviewsPerSession',
'prettyPrint':'true',
},
chart: {
'container': 'chart-5-container',
'type': 'TABLE',
'options': {
'width': '100%',
'title': 'test'
}
}
});
dataChart5.on('success', function(response) {
response.data.cols[0].label = "test1"; //here I edit the response
console.log(response);
});
dataChart5.execute();
Using the console.log(response); I can see that the record label gets modified but the chart gets populated before the edit.

I think a have a workaround. It has problems, but might be useful. While handling the success event, call a function that will recursively walk through the child elements of $('#chart-5-container') and apply your formatting there.
One problem with that approach is that the positions of the elements won't be recalculated. Therefore, with different string sizes you might get overlapping strings. Moreover, it seems not to be affecting the tooltip.
I'm using this approach to translate to Portuguese.
function recursiveTranslate(e) {
var key = e.html(),
dict = {};
dict['Date'] = 'Data';
dict['Users'] = 'Visitantes';
dict['Sessions'] = 'Visitas';
dict['Pageviews'] = 'Visualizações';
if (key in dict) {
e.html(dict[key]);
}
for (var i = 0; i < e.children().length; i++) {
recursiveTranslate($(e.children()[i]));
}
}
Then I call recursiveTranslate inside the success event:
dataChart5.on('success', function h(obj) {
recursiveTranslate($('#chart-5-container'));
});
It is not elegant and has a lot of issues. I would really like to get my hands on the proper solution.

Mapbox GL and .net core webApi

I am moving from Leaflet to Mapbox GL and have some data issues. My webApi is proven but I cannot smoothly integrate them.
The approach I gave up on, based upon their examples and my own research, looks like:
map = new mapboxgl.Map({
container: 'mapdiv',
style: 'mapbox://styles/mapbox/streets-v10'
, center: start
, zoom: $scope.zoom
, transformRequest: (url, resourceType) => {
if (resourceType === 'Source' && url.startsWith(CONFIG.API_URL)) {
return {
headers: {
'Authorization': 'Bearer ' + localStorageService.get("authorizationData")
, 'Access-Control-Allow-Origin': CONFIG.APP_URL
, 'Access-Control-Allow-Credentials': 'true'
}
}
}
}
});
This is passing my OAuth2 token (or at least I think it should be) and the Cross site scripting part CORS.
Accompanying the above with:
map.addSource(layerName, { type: 'geojson', url: getLayerURL($scope.remLayers[i]) });
map.getSource(layerName).setData(getLayerURL($scope.remLayers[i]));
Having also tried to no avail:
map.addSource(layerName, { "type": 'geojson', "data": { "type": "FeatureCollection", "features": [] }});
map.getSource(layerName).setData(getLayerURL($scope.remLayers[i]));
Although there are no errors Fiddler does not show any requests being made to my layer webApi. All the others show but Mapbox does not appear to raising them.
The Url looks like:
http://localhost:49198/api/layer/?bbox=36.686654090881355,34.72821077223763,36.74072742462159,34.73664000652042&dtype=l&id=cf0e1df7-9510-4d03-9319-d4a1a7d6646d&sessionId=9a7d7daf-76fc-4dd8-af4f-b55d341e60e4
Because this was not working I attempted to make it more manual using my existing $http calls which partially works.
map = new mapboxgl.Map({
container: 'mapdiv',
style: 'mapbox://styles/mapbox/streets-v10'
, center: start
, zoom: $scope.zoom
, transformRequest: (url, resourceType) => {
if (resourceType === 'Source' && url.startsWith(CONFIG.API_URL)) {
return {
headers: {
'Authorization': 'Bearer ' + localStorageService.get("authorizationData")
}
}
}
}
});
map.addSource(layerName,
{
"type": 'geojson',
"data": { "type": "FeatureCollection", "features": [] }
});
The tricky part is to know when to run the data retrieval call. The only place I could find was on the maps data event which now looks like:
map.on('data', function (e) {
if (e.dataType === 'source' && e.isSourceLoaded === false && e.tile === undefined) {
// See if the datasource is known
for (var i = 0; i < $scope.remLayers.length; i++) {
if (e.sourceId === $scope.remLayers[i].name) {
askForData(i)
}
}
}
});
function askForData(i) {
var data = getBBoxString(map);
var mapZoomLevel = map.getZoom();
if (checkZoom(mapZoomLevel, $scope.remLayers[i].minZoom, $scope.remLayers[i].maxZoom)) {
mapWebSvr.getData({
bbox: data, dtype: 0, id: $scope.remLayers[i].id, buffer: $scope.remLayers[i].isBuffer, sessionId
},
function (data, indexValue, indexType) {
showNewData(data, indexValue, indexType);
},
function () {
// Not done yet.
},
i,
0
);
}
}
function showNewData(ajxresponse, index, indexType) {
map.getSource($scope.remLayers[index].name).setData(ajxresponse);
map.getSource($scope.remLayers[index].name).isSourceLoaded = true;
}
This is all working with one exception. It keeps firing time and time again. Some of these calls return a lot of data for a web call so its not a solution at the moment.
Its like its never satisfied with the data even though its showing it on the map!
There is a parameter on the data event, isSourceLoaded but it does not get set to true.
I have searched for an example, have tried setting isSourceLoaded in a number of places (as with the code above) but to no avail.
Does anyone have a method accomplishing this basic data retrieval function successfully or can point out the error(s) in my code? Or even point me to a working example...
I have spent too long on this now and could do with some help.
After a bit of a run around I have a solution.
A Mapbox email pointed to populating the data in the load event - which I am now doing.
This was not however the solution I was looking for as the data needs refreshing when the map moves, zooms etc - further look ups are required.
Following a bit more a examination a solution was found.
Using the code blow on the render event will request the information when the bounding box is changed.
var renderStaticBounds = getBoundsString(map.getBounds());
map.on('render', function (e) {
if (renderStaticBounds != getBoundsString(map.getBounds())) {
renderStaticBounds = getBoundsString(map.getBounds());
for (var i = 0; i < $scope.remLayers.length; i++) {
askForData(i);
}
}
});
function getBoundsString(mapBounds) {
var left = mapBounds._sw.lng;
var bottom = mapBounds._sw.lat;
var right = mapBounds._ne.lng;
var top = mapBounds._ne.lat;
return left + ',' + bottom + ',' + right + ',' + top;
}
This hopefully will save someone some development time.

Dynamically toggle resource column visibility

I have a FullCalendar scheduler on a webapp which has 2 way databinding for resources and events, all working great. I want to be able to present the user with a dropdown that enables them to toggle the visibility of a column, ideally completely client side.
I have tried a combination of addResource / removeResource however my issue here is that a rerender of the calendar (e.g. when a new event is added) then displays the previously removed resource. I can work around this however would prefer a really simple approach using JS / CSS. I currently cannot find a way to set a resource to not be visible, or to have zero width - is this possible?
There is an easy way to do this:
Store resources in an array variable resourceData.
Create another array called visibleResourceIds to store the ids of any resources you want to show.
In the resources callback function, filter resourceData to only contain the resources where the resource id exists in visibleResourceIds. Return the filtered array and fullcalendar will only add the desired resources for you.
To remove a resource from view, simply remove the resource id from visibleResourceIds and refetchResources. To add the resource back in, add the id to visibleResourceIds and refetchResources. DONE.
JSFiddle
var resourceData = [
{id: "1", title: "R1"},
{id: "2", title: "R2"},
{id: "3", title: "R3"}
];
var visibleResourceIds = ["1", "2", "3"];
// Your button/dropdown will trigger this function. Feed it resourceId.
function toggleResource(resourceId) {
var index = visibleResourceIds.indexOf(resourceId);
if (index !== -1) {
visibleResourceIds.splice(index, 1);
} else {
visibleResourceIds.push(resourceId);
}
$('#calendar').fullCalendar('refetchResources');
}
$('#calendar').fullCalendar({
defaultView: 'agendaDay',
resources: function(callback) {
// Filter resources by whether their id is in visibleResourceIds.
var filteredResources = [];
filteredResources = resourceData.filter(function(x) {
return visibleResourceIds.indexOf(x.id) !== -1;
});
callback(filteredResources);
}
});
I had the same challenge. Instead of a dropdown, I use checkboxes, but the workings will be the same.
My resources are stored in a variable, when I uncheck a box, the resource is removed and the resource's object is added to another array with the resourceId as key, and the index added to the object to restore the object in the same column as it originally was. When re-checking the box, the object is added to the resources array and the resources refetched.
/* retrieve the resources from the server */
var planningResources;
var removedResource = [];
$.ajax({
url: '/planning/resources/',
method: 'get',
success: function (response) {
planningResources = response;
showCalendar();
}
, error: function () {
if (typeof console == "object") {
console.log(xhr.status + "," + xhr.responseText + "," + textStatus + "," + error);
}
}
});
/* create the calendar */
showCalendar = function () {
$('#calendar').fullCalendar({
...
});
}
/* checkbox on click */
$('.resource').click(function() {
var resourceId = $(this).val();
var hideResource = !$(this)[0].checked;
$('.status:checkbox:checked').each(function () {
});
if(hideResource) {
$.each(planningResources, function(index, value){
if( value && value.id == resourceId ) {
value.ndx = index;
removedResource[resourceId] = value;
planningResources.splice(index,1);
return false;
}
});
$('#planningoverview').fullCalendar(
'removeResource',
resourceId
);
}
else {
planningResources.splice(removedResource[resourceId].ndx, 0, removedResource[resourceId]);
$('#planningoverview').fullCalendar('refetchResources');
}
});
showCalendar();
It probably doesn't get first price in a beauty contest, but it works for me ...
Cheers
You can use the resourceColumns option for this. In the column objects you can set the width property to a number of pixels or a percentage. If you pass a function here you can easily handle the width property someplace else. Your hide/show function can then set the width to 0 to hide the column. After that you can trigger reinitView to update the view: $('#calendar').fullCalendar("reinitView");

Backbone Collection.fetch() returns first item null

I'm using the following code in my view to fetch my collection from the server:
initialize: function () {
_this = this;
this.collection.fetch({
success : function(collection, response) {
_.each(response, function(i){
var todo = new TodosModel({
id: i.id,
content: i.content,
completed: i.completed
});
// Add to collection
_this.collection.add(todo);
// Render
_this.render(todo);
});
},
error : function(collection, response) {
console.log('ERROR GETTING COLLECTION!');
}
});
},
Which seems to work - here's the output from my server:
{
"0": {
"id": 1,
"content": "one",
"completed": false
},
"3": {
"id": 4,
"content": "two",
"completed": true
},
"4": {
"id": 5,
"content": "tester",
"completed": false
}
}
Except for the fact that if I log out my collection there is a null entry in the first position:
Which then causes issues as if I add an item it takes the ID of the last element. I'm new to backbone and am hoping I'm just missing something simple.
Here's my crack at a quick run through of your code. I haven't tested anything so there might be typos. I'm still not sure where the stray empty model is coming from but if you restructure your application as outlined below, I suspect the problem will go away.
The model and collection look okay so let us have a look at your view.
el: $('#todos'),
listBlock: $('#todos-list'),
newTodoField: $('#add input'),
//...
template: $('#todo-template').html(),
//...
events: { /* ... */ },
These should be okay but you need to ensure that all those elements are in the DOM when your view "class" is loaded. Usually you'd compile the template once:
template: _.template($('#todo-template').html()),
and then just use this.template as a function to get your HTML. I'll assume that template is a compiled template function below.
initialize: function () {
_this = this;
You have an accidental global variable here, this can cause interesting bugs. You want to say var _this = this;.
this.el = $(this.el);
Backbone already gives you a jQuery'd version of el in $el so you don't need to do this, just use this.$el.
this.collection.fetch({
success : function(collection, response) {
_.each(response, function(i) {
var todo = new TodosModel({ /* ... */ });
// Add to collection
_this.collection.add(todo);
// Render
_this.render(todo);
});
},
//...
The collection's fetch will add the models to the collection before the success handler is called so you don't have to create new models or add anything to the collection. Generally the render method renders the whole thing rather than rendering just one piece and you bind the view's render to the collection's "reset" event; the fetch call will trigger a "reset" event when it has fetched so the usual pattern looks like this:
initialize: function() {
// So we don't have to worry about the context. Do this before you
// use `render` or you'll have reference problems.
_.bindAll(this, 'render');
// Trigger a call to render when the collection has some stuff.
this.collection.on('reset', this.render);
// And go get the stuff we want. You can put your `error` callback in
// here if you want it, wanting it is a good idea.
this.collection.fetch();
}
Now for render:
render: function (todo) {
var templ = _.template(this.template);
this.listBlock.append(templ({
id: todo.get('id'),
content: todo.get('content'),
completed: todo.get('completed')
}));
// Mark completed
if(todo.get('completed')) {
this.listBlock.children('li[data-id="'+todo.get('id')+'"]')
.addClass('todo-completed');
}
}
Normally this would be split into two pieces:
render to render the whole collection.
Another method, say renderOne, to render a single model. This also allows you to bind renderOne to the collection's "add" event.
So something like this would be typical:
render: function() {
// Clear it out so that we can start with a clean slate. This may or
// may not be what you want depending on the structure of your HTML.
// You might want `this.listBlock.empty()` instead.
this.$el.empty();
// Punt to `renderOne` for each item. You can use the second argument
// to get the right `this` or add `renderOne` to the `_.bindAll` list
// up in `initialize`.
this.collection.each(this.renderOne, this);
},
renderOne: function(todo) {
this.listBlock.append(
this.template({
todo: todo.toJSON()
})
)
// Mark completed
if(todo.get('completed')) {
this.listBlock.find('li[data-id="' + todo.id + '"]')
.addClass('todo-completed');
}
}
Notice the use of toJSON to supply data to the template. Backbone models and collections have a toJSON method to give you a simplified version of the data so you might as well use it. The model's id is available as an attribute so you don't have to use get to get it. You could (and probably should) push the todo-completed logic into the template, just a little
<% if(completed) { %>class="completed"<% } %>
in the right place should do the trick.
addTodo: function (e) {
//...
var todo = new TodosModel({
id: todoID,
content: todoContent,
completed: todoCompleted
});
this.render(todo);
todo.save();
_this.collection.add(todo);
You could bind renderOne to the collection's "add" event to take care of rendering the new model. Then use the save callbacks to finish it off:
var _this = this;
var todo = new TodosModel({ /* ... */ });
todo.save({}, {
wait: true,
success: function(model, response) {
// Let the events deal with rendering...
_this.collection.add(model);
}
});
Again, an error callback on the save might be nice.
completeTodo: function (e) {
//...
todo.save({
completed: todoCompleted
});
}
The save call here will trigger a 'change:completed' event so you could bind to that to adjust the HTML.
removeTodo: function (e) {
//...
}
The destroy call will trigger a "destroy" event on the model and on the collection:
Any event that is triggered on a model in a collection will also
be triggered on the collection directly, for convenience. This
allows you to listen for changes to specific attributes in any model
in a collection, [...]
So you could listen for "destroy" events on the collection and use those to remove the TODO from the display. And destroying the model should remove it from the collection without your intervention.
printColl: function () {
this.collection.each(function (todo) {
console.log('ID: '+todo.get('id')+' | CONTENT: '+todo.get('content')+' | COMPLETED: '+todo.get('completed'));
});
}
You could just console.log(this.collection.toJSON()) instead,
you'd have to click around a little to open up the stuff in the
console but you wouldn't miss anything that way.
All the event binding for the collection would take place in your
view's initialize method. If you're going to remove the view then
you'd want to override the remove to unbind from the collection
to prevent memory leaks:
remove: function() {
// Call this.collection.off(...) to undo all the bindings from
// `initialize`.
//...
// Then do what the default `remove` does.
this.$el.remove()
}
You could also use a separate view for each TODO item but that might be overkill for something simple.

Backbone.js: correct way of filtering a collection?

The current method I'm using is to filter a collection, which returns an array, and use
collection.reset(array)
to re-populate it. However, this modifies the original collection, so I added an array called "originalCollectionArray" which keeps track of the initial array state of the collection. When no filtering is active I simply use
collection.reset(originalCollectionArray)
But then, I need to keep track of adding and removing models from the real collection, so I did this:
// inside collection
initialize: function(params){
this.originalCollectionArray = params;
this.on('add', this.addInOriginal, this);
this.on('remove', this.removeInOriginal, this);
},
addInOriginal: function(model){
this.originalCollectionArray.push(model.attributes);
},
removeInOriginal: function(model){
this.originalTasks = _(this.originalTasks).reject(function(val){
return val.id == model.get('id');
});
},
filterBy: function(params){
this.reset(this.originalCollectionArray, {silent: true});
var filteredColl = this.filter(function(item){
// filter code...
});
this.reset(filteredColl);
}
This is quickly becoming cumbersome as I try to implement other tricks related to the manipulation of the collection, such as sorting. And frankly, my code looks a bit hacky. Is there an elegant way of doing this?
Thanks
You could create a collection as a property of the main collection reflecting the state of the filters:
var C = Backbone.Collection.extend({
initialize: function (models) {
this.filtered = new Backbone.Collection(models);
this.on('add', this.refilter);
this.on('remove', this.refilter);
},
filterBy: function (params){
var filteredColl = this.filter(function(item){
// ...
});
this.filtered.params = params;
this.filtered.reset(filteredColl);
},
refilter: function() {
this.filterBy(this.filtered.params);
}
});
The parent collection keeps its models whatever filters you applied, and you bind to the filtered collection to know when a change has occurred. Binding internally on the add and remove events lets you reapply the filter. See
http://jsfiddle.net/dQr7X/ for a demo.
The major problem on your code is that you are using a raw array as original, instead of a Collection. My code is close to the yours but use only Collections, so methods like add, remove and filter works on the original:
var OriginalCollection = Backbone.Collection.extend({
});
var FilteredCollection = Backbone.Collection.extend({
initialize: function(originalCol){
this.originalCol = originalCol;
this.on('add', this.addInOriginal, this);
this.on('remove', this.removeInOriginal, this);
},
addInOriginal: function(model){
this.originalCol.add(model);
},
removeInOriginal: function(model){
this.originalCol.remove(model);
},
filterBy: function(params){
var filteredColl = this.originalCol.filter(function(item){
// filter code...
});
this.reset(filteredColl);
}
});

Persisting json data in jstree through postback via asp:hiddenfield

I've been pouring over this for hours and I've yet to make much headway so I was hoping one of the wonderful denizens of SO could help me out. Here's the problem...
I'm implementing a tree via the jstree plugin for jQuery. I'm pulling the data with which I populate the tree programatically from our webapp via json dumped into an asp:HiddenField, basically like this:
JavaScriptSerializer serializer = new JavaScriptSerializer();
string json = serializer.Serialize(Items);
json = json.ToLower();
data.Value = json;
Then, the tree pulls the json from the hidden field to build itself. This works perfectly fine up until I try to persist data for which nodes are selected/opened. To simplify my problem I've hardcoded some json data into the tree and attempted to use the cookie plugin to persist the tree state data. This does not work for whatever reason. I've seen other issues where people need to load the plugins in a specific order, etc, this did not solve my issue. I tried the same setup with html_data and it works perfectly. With this working persistence I converted the cookie plugin to persist the data in a different asp:hiddenfield (we can't use cookies for this type of thing in our application.)
essentially the cookie operations are identical, it just saves the array of nodes as the value of a hidden field. This works with the html_data, still not with the json and I have yet to be able to put my finger on where it's failing.
This is the jQuery.cookie.js replacement:
jQuery.persist = function(name, value) {
if (typeof value != 'undefined') { // name and value given, set persist
if (value === null) {
value = '';
}
jQuery('#' + name).attr('value', value);
} else { // only name given, get value
var persistValue = null;
persistValue = jQuery('#' + name).attr('value');
return persistValue;
}
};
The jstree.cookie.js code is identical save for a few variable name changes.
And this is my tree:
$(function() {
$("#demo1").jstree({
"json_data": {
"data" : [
{
"data" : "A node",
"children" : [ "Child 1", "Child 2" ]
},
{
"attr": { "id": "li.node.id" },
"data" : {
"title": "li.node.id",
"attr": { "href": "#" }
},
"children": ["Child 1", "Child 2"]
}
]
},
"persistence": {
"save_opened": "<%= open.ClientID %>",
"save_selected": "<%= select.ClientID %>",
"auto_save": true
},
"plugins": ["themes", "ui", "persistence", "json_data"]
});
});
The data -is- being stored appropriately in the hiddenfields, the problem occurs on a postback, it does not reopen the nodes. Any help would be greatly appreciated.
After looking through this some more, I just wanted to explain that it appears to me that the issue is that the tree has not yet been built from the JSON_data when the persistence operations are being attempted. Is there any way to postpone these actions until after the tree is fully loaded?
If anyone is still attempting to perform the same type of operation on a jsTree version 3.0+ there is an easier way to accomplish the same type of functionality, without editing any of the jsTree's core JavaScript, and without relying on the "state" plugin (Version 1.0 - "Persistence"):
var jsTreeControl = $("#jsTreeControl");
//Can be a "asp:HiddenField"
var stateJSONControl = $("#stateJSONControl");
var url = "exampleURL";
jsTreeControl.jstree({
'core': {
"data": function (node, cb) {
var thisVar = this;
//On the initial load, if the "state" already exists in the hidden value
//then simply use that rather than make a AJAX call
if (stateJSONControl.val() !== "" && node.id === "#") {
cb.call(thisVar, { d: JSON.parse(stateJSONControl.val()) });
}
else {
$.ajax({
type: "POST",
url: url,
async: true,
success: function (json) {
cb.call(thisVar, json);
},
contentType: "application/json; charset=utf-8",
dataType: "json"
}).responseText;
}
}
}
});
//If the user changes the jsTree, save the full JSON of the jsTree into the hidden value,
//this will then be restored on postback by the "data" function in the jsTree decleration
jsTreeControl.on("changed.jstree", function (e, data) {
if (typeof (data.node) != 'undefined') {
stateJSONControl.val(JSON.stringify(jsTreeControl.jstree(true).get_json()));
}
});
This code will create a jsTree and save it's "state" into a hidden value, then upon postback when the jsTree is recreated, it will use its old "state" restored from the "HiddenField" rather than make a new AJAX call and lose the expansions/selections that the user has made.
Got it working properly with JSON data. I had to edit the "reopen" and "reselect" functions inside jstree itself.
Here's the new functioning reopen function for anyone who needs it.
reopen: function(is_callback) {
var _this = this,
done = true,
current = [],
remaining = [];
if (!is_callback) { this.data.core.reopen = false; this.data.core.refreshing = true; }
if (this.data.core.to_open.length) {
$.each(this.data.core.to_open, function(i, val) {
val = val.replace(/^#/, "")
if (val == "#") { return true; }
if ($(("li[id=" + val + "]")).length && $(("li[id=" + val + "]")).is(".jstree-closed")) { current.push($(("li[id=" + val + "]"))); }
else { remaining.push(val); }
});
if (current.length) {
this.data.core.to_open = remaining;
$.each(current, function(i, val) {
_this.open_node(val, function() { _this.reopen(true); }, true);
});
done = false;
}
}
if (done) {
// TODO: find a more elegant approach to syncronizing returning requests
if (this.data.core.reopen) { clearTimeout(this.data.core.reopen); }
this.data.core.reopen = setTimeout(function() { _this.__callback({}, _this); }, 50);
this.data.core.refreshing = false;
}
},
The problem was that it was trying to find the element by a custom attribute. It was just pushing these strings into the array to search when it was expecting node objects. Using this line
if ($(("li[id=" + val + "]")).length && $(("li[id=" + val + "]")).is(".jstree-closed")) { current.push($(("li[id=" + val + "]"))); }
instead of
if ($(val).length && $(val).is(".jstree-closed")) { current.push(val); }
was all it took. Using a similar process I was able to persist the selected nodes this way as well.
Hope this is of help to someone.
