I have json result as shown below. In my QML project I want to parse the json which I did help of How to show data in QML json request . Now I want to set 4 flag. Local flag, USA, UK and Europe in one row. And I will add as shown below.
My question is how to use QML Model, Delegate, Repeater, View? And which view is beter solution to have?
{ "tarih": "20171212",
"currency": {
"usa": { "buy": "3,7900", "sell": "3,8800", "e_buy": "3,7900" },
"stg": { "buy": "5,0700", "sell": "5,1650", "e_buy": "5,0700" },
"eur": { "buy": "4,4700", "sell": "4,5600", "e_buy": "4,4700" }
}
}
thank you
UPDATE:
Easiest way to do it is this:
Parse json with;
(var result = JSON.parse(request.responseText))
And I get items with this:
(getUsaBuy.text = result.currency.usa.buy)
I motife my original post from How to show data in QML json request.
Running Code:
if (request.readyState === XMLHttpRequest.DONE) {
if (request.status && request.status === 200) {
var result = JSON.parse(request.responseText)
// BUY
textSTG_BUY.text = **result.currency.stg.buy**
// SELL
textSTG_SELL.text = **result.currency.stg.sell**
}
else {
console.log("Log:", request.status, request.statusText)
}
}

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 < $scope.remLayers.length; i++) {
askForData(i);
}
}
});
function getBoundsString(mapBounds) {
var left = mapBounds._sw.lng;
var bottom = mapBounds._sw.lat;
var right = mapBounds._ne.lng;
var top = mapBounds._ne.lat;
return left + ',' + bottom + ',' + right + ',' + top;
}
This hopefully will save someone some development time.
When I am editing a report, I can click on "Report Code" to see information about the report structure. It loks like this:
{
"classID": "ic3.ReportGuts",
"guts_": {
"ic3Version": 12,
"schemaName": "test_schema",
"cubeName": "Cube",
"layout": {
"classID": "ic3.FixedLayout",
"guts_": {
"ic3Version": 12,
"grid": 10,
"boxes": [
{
"classID": "ic3.FixedLayoutBox",
"guts_": {
"ic3Version":...
How can I access this Information with Javascript? context.$report apparently doesn't give this information.
Also is there a way to get the information, what MDX statements are used in the different charts of a report? And can this be altered with Javascript?
To get report guts add this code to the Report Code:
function consumeEvent( context, event ) {
if (event.name == 'ic3-report-init') {
console.log(event.value.state.report);
}
}
As for handling mdx request before send, it's kinda harder. Again in ReportCode:
function consumeEvent( context, event ) {
if (event.name == 'ic3-report-init') {
event.value.widgetMgr().forEach(function(idx,item){
if(item.hasOwnProperty('onVizBeforeRequestSend')){
return;
}
var oldMethod = item.onVizBeforeRequestSend.bind(item);
item.onVizBeforeRequestSend = function(request){
console.log(item, request);
oldMethod(request);
}
});
}
In this function item is widgetAdapter with info about the widget and request is request instance.
I'd like to perform the equivalent of this Mongo shell command in meteor(server-side, of course):
db.articles.find(
{ $text: { $search: "apple pie" } },
{ score: { $meta: "textScore" } }
).sort( { score: { $meta: "textScore" } } ).limit(10)
I have been able to do:
return Articles.find( { $text: { $search: "apple" } },
{ sort: {"name":1}, limit:20});
However, searching for "pie apple" doesn't work - it only does exact matching. Neither does trying to sort by score.
I am using mongo 2.6.3 with a text index on the name field in articles. Searching from within mongo shell works perfectly.
Also, has anyone successfully implemented a text search with a different approach? My database has 10k entries and I only need to search within a single field, and return 20 best matches.
3 steps (meteor 1.0.4+) now using MongoDB 3.0. Assuming you already have the YourCollection collection i.e.
YourCollection = new Meteor.Collection("yourCollection");
A. Index your collection (server side) here below is how to index all the fields, more info here
Meteor.startup(function (){
YourCollection._ensureIndex(
{"$**": "text"},
{"name": "searchIndex"}
); }
B. Create the publication (server side)
Meteor.publish("search-yourCollection", function(searchField)
{
return YourCollection.find({"$text": {"$search": searchField}},
{
fields: {
score: {$meta: "textScore"}
},
sort: {
score: {$meta: "textScore"}
}
});
});
C. Subscribe to the publication and find (client side)
var whatToSearch = "abc"; // can be taken out of the session
Meteor.subscribe("search-yourCollection", whatToSearch);
var results = YourCollection.find({score:{"$exists":true}});
Remark: The publication will add a score property to all the returned items. Ensuring this property exists within the find function {"$exists":true} will make sure you are finding the elements returned by the search-yourCollection publication. This is mandatory if you are subscribing to another publication adding items into YourCollection published set.
I've been able to get this to work using something similar to:
Implementing MongoDB 2.4's full text search in a Meteor app
The differences are:
MongoInternals.defaultRemoteCollectionDriver().mongo.db.executeDbCommand
and the searchDinosaurs function in the link above looks like:
if (query && query !== '') {
var searchResults = _searchArticles(query);
var results = [];
for (var i = 0; i < searchResults.length; i++) {
results.push({
id: searchResults[i].obj._id,
score: searchResults[i].score});
}
var ids = [];
results.sort(function(a,b) { return a.score < b.score } );
for (var i = 0; i < 20; i++) {
if (results[i]!=null){
ids.push(results[i].id);
}
}
return ids;
Here I'm sorting the results on score and returning the top 20 id's. The only issue is, once the user is subscribed to these 20 articles, I have to find and sort them once again client-side using regex search in minimongo. If anyone has suggestions or improvements, I'd love to hear them.
All, Forgive me I am not familiar with the ASP.NET Ajax. I knew the method Create is attaching an html element to ajax component. But I don't know how to detach it from the current component . and attach another one.
Let's say there is a element ctl00_PlaceHolderMain_UserRegistration_txbPassword1 has been attached to a component type AccelaWebControlExtender.HelperBehavior, and the created component id is ctl00_PlaceHolderMain_UserRegistration_txbPassword1_helper_bhv. The code looks like below. please review it .
Sys.Application.add_init(function() {
$create(AccelaWebControlExtender.HelperBehavior, {"closeTitle":"Close","id":"ctl00_PlaceHolderMain_UserRegistration_txbPassword1_helper_bhv","isRTL":false,"title":"Help"}, null, null, $get("ctl00_PlaceHolderMain_UserRegistration_txbPassword1"));
});
I think firstly I should retrieve the component by id, then do the detach and attach work. Hope someone can give me some help.Thanks.
After doing some research, I found It is called Extend Web server control that encapsulates a client behavior in Asp.net Ajax, And I found the attachment of component is done by Asp.net automatically . We can see the Sys.Application.add_init(function() code is generated in the aspx page by Asp.net automatically. So if we want to customize the original behavior of Web Server Control, I believe it can be made in the Javascript OOP way(old and same).
For example :
If the original behavior code is blow.
// Register the namespace for the control.
Type.registerNamespace('Samples');
//
// Define the behavior properties.
//
Samples.FocusBehavior = function(element) {
Samples.FocusBehavior.initializeBase(this, [element]);
this._highlightCssClass = null;
this._nohighlightCssClass = null;
}
//
// Create the prototype for the behavior.
//
Samples.FocusBehavior.prototype = {
initialize : function() {
Samples.FocusBehavior.callBaseMethod(this, 'initialize');
$addHandlers(this.get_element(),
{ 'focus' : this._onFocus,
'blur' : this._onBlur },
this);
this.get_element().className = this._nohighlightCssClass;
},
dispose : function() {
$clearHandlers(this.get_element());
Samples.FocusBehavior.callBaseMethod(this, 'dispose');
},
//
// Event delegates
//
_onFocus : function(e) {
if (this.get_element() && !this.get_element().disabled) {
this.get_element().className = this._highlightCssClass;
}
},
_onBlur : function(e) {
if (this.get_element() && !this.get_element().disabled) {
this.get_element().className = this._nohighlightCssClass;
}
},
//
// Behavior properties
//
get_highlightCssClass : function() {
return this._highlightCssClass;
},
set_highlightCssClass : function(value) {
if (this._highlightCssClass !== value) {
this._highlightCssClass = value;
this.raisePropertyChanged('highlightCssClass');
}
},
get_nohighlightCssClass : function() {
return this._nohighlightCssClass;
},
set_nohighlightCssClass : function(value) {
if (this._nohighlightCssClass !== value) {
this._nohighlightCssClass = value;
this.raisePropertyChanged('nohighlightCssClass');
}
}
}
// Optional descriptor for JSON serialization.
Samples.FocusBehavior.descriptor = {
properties: [ {name: 'highlightCssClass', type: String},
{name: 'nohighlightCssClass', type: String} ]
}
// Register the class as a type that inherits from Sys.UI.Control.
Samples.FocusBehavior.registerClass('Samples.FocusBehavior', Sys.UI.Behavior);
if (typeof(Sys) !== 'undefined') Sys.Application.notifyScriptLoaded();
I think we can override some of the methods of the Javascript Object Samples.FocusBehavior and it's prototype object to achieve customization.
For example .
I can override Samples.FocusBehavior.prototype._onFocus in the script like this.
Samples.FocusBehavior.prototype._onFocus = function (e) {
alert('test');
if (this.get_element() && !this.get_element().disabled) {
this.get_element().className = this._highlightCssClass;
}
};
Just make sure this code is parsed after original one by Browser.
I am not sure if this is the right way to make it . I hope someone can help to verify it .Thank you very much.
Here is a tutorial of it. please review it .
Cheers.
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.
