I have this helper in Meteor:
itemMenuAddOns: function(_id){
console.log(_id); //OK
var addOns = RestMenuItems.find({_id:_id}, {addOns: 1});
if(addOns){
console.log(addOns); //OK, an object where in the collection/map I see the expected array.
addOns.forEach( function(addOn) { console.log(addOn.title); } )// displays nothing
}
}
The problem is that the forEach console.log displays nothing. In both cases, if I use addOn.title or just even 123, to display.
thanks.
Well I had passed a wrong id and used find instead of findOne.
Now it works. for anyone interested:
itemMenuAddOns: function(_id){
var list = '';
var cursor = RestMenuItems.findOne({_id:_id}, {addOns: 1});
if(cursor){
cursor.addOns.forEach( function(addOn) {
var addOn = RestMenuSideItems.findOne({_id: addOn});
list += Spacebars.SafeString("<div>" + addOn.title + "</div>")});
return list;
}
}

I have an array of integers called data which I would like to send from my View to a specific controller, I could see that i can send integers and strings and it works with the code that I have so far, but when I try to send an array I can get the data correctly.
This is the code that I have in my view, it is something simple just to be in perspective.
function SeeStation() {
var data = [];
var i = 0;
$("input:checkbox:checked").each(function () {
data[i] = $(this).val();
});
window.location.href = "#Url.Action("ExportData", "Dispatch")?id=" + data;
}
and this is the code in the controller. I know it doesn't make much sense but so far I am focused on correctly obtaining the array by parameter.
public ActionResult ExportData(int[] id)
{
var data = cn.ESTACIONDESPACHOes.ToList();
return View(data);
}
In my array data I store something like this [1,2,3] and I would like to get something similar in the controller array id.
It will not bind like that.
To get the id array in your action you need to have the link at the end like this: *Dispatch/ExportData?id=1&id=2&id=3*
Your "#Url.Action("ExportData", "Dispatch")?id=" + data; will not generate that (data will give the numbers separated with commas).
You can just build the query string when you enumerate the checkboxes.
function SeeStation() {
var data = '';
$("input:checkbox:checked").each(function () {
data += 'id='$(this).val() + '&';
});
window.location.href = "#Url.Action("ExportData", "Dispatch")?" + data;
}
You will have a "&" in the end. You can easily remove it, but it will not affect anything.
There may be better ways to do this though, but I just used your function.
try
#Url.Action("ExportData", "Dispatch", new { id= [1,2,3] })
Store the Values in the Hidden Fields
#Html.HiddenFor(m => m.Ids, new { #Value = [1,2,3] })
Then Using the Ajax Get Method Pass the Hidden fields
In the Controller Method Convert the sting to array using string extension method
function SeeStation() {
var data = [];
var i = 0;
$("input:checkbox:checked").each(function () {
data[i] = $(this).val();
});
location.href = '#Url.Action("ExportData", "Dispatch")?id=' + data;
}
Please remove window keyword.
I am attempting to piece together an example from ml5 on image style transfer (https://ml5js.org/docs/style-transfer-image-example) with p5.js examples parsing a JSON of image URLs, and adding them to an array to display as images. I am hitting a dead end as I do not think I fully understand the ways that p5 stores images in an array, nor do I fully understand the difference between createImg() createImage() or loadImage() (which one to use!!)
The goal is to use Bing image API to return a list of URLS from a search (this part is working fine) and run those images through a pretrained model (this part is working fine when just used on a local image). It is the bringing the two together that I am unable to figure out. Any suggestions or advice (is this even possible??!) greatly appreciated.
I have already tried loading images into an array and iterating through the array in the draw() function. The problem happens when I need to address an image in order to actually apply the style transfer model. It seems like my array is empty when I attempt to refer to it anywhere except draw(). I am sure I am thinking about this incorrectly.
var imageData;
let imgArray = [];
var w = (window.innerWidth)/3;
var h = (window.innerHeight)/4;
var index = 0;
var xPos = 0;
var yPos = 0;
var indexMax = 3;
let style;
let resultImg;
function preload() {
loadData();
}
function loadData(){
var url = api + search + subscriptionKey;
loadJSON(url, gotData);
}
function gotData(data) {
imageData = data;
for (var i=0; i < indexMax; i++){
_url = imageData.value[i].contentUrl;
imgArray.push(loadImage(_url));
}
function displayImages(){
if (index < 3){
index++;
} else {
index = 0;
};
function setup() {
createCanvas(1200, 800).parent('canvasContainer');
var button = select('#display');
button.mousePressed(displayImages);
var transferBtn = select('#transferBtn');
transferBtn.mousePressed(transferImages);
//create style method
style = ml5.styleTransfer('/model', modelLoaded);
}
function draw() {
image(imgArray[index], xPos, yPos, w, h);
}
//ml5 stuff
function modelLoaded() {
if (style.ready){
select('#status').html('Model Loaded');
//style.transfer(gotResult);
}
}
function transferImages(){
select('#status').html('applying style transfer');
style.transfer(tempImg, function(err, result){
createImg(result.src);
});
select('#status').html('done');
}
I am attempting to (unsuccessfully) create a "tempImg" from imgArray[0] to try to figure out where this createImage needs to go, but have not gotten this to work. I have CORS enabled, so I didnt think this was the problem, but am getting the following error. Please help me understand how to think about this differently.
You should use loadImage instead of createImg.
style.transfer(tempImg, function(err, result){
p5CompatibleImage = loadImage(result.src);
});
I'm working on a requirement where I have a datasource named 'emailSearchResults' where I search for email messages metadata and load the results in the datasource.
The fields in the datasource are not relevant, however I set the datasource to have 50 records per page as per the below screenshot:
The script I used to load the datasource is shown in the query field, that call the following script:
function getMessageDetails(userId, msgID)
{
var messageDetails = [];
var messageData;
var msgID_,subject_,from_,date_;
messageData=Gmail.Users.Messages.get(userId,msgID,{format:"metadata", metadataHeaders:["Message-ID", "Subject", "From", "Date"]});
console.log(messageData.payload.headers);
//console.log(msgID);
//console.log(messageData.payload.headers[3].value);
date_="<na>";
from_="<na>";
subject_="<na>";
msgID_="<na>";
for (var counter =0;counter<4;counter++)
{
if (messageData.payload.headers[counter].name=="Message-ID")
{
msgID_=messageData.payload.headers[counter].value;
}
if (messageData.payload.headers[counter].name=="Subject")
{
subject_=messageData.payload.headers[counter].value;
}
if (messageData.payload.headers[counter].name=="From")
{
from_=messageData.payload.headers[counter].value;
}
if (messageData.payload.headers[counter].name=="Date")
{
date_=messageData.payload.headers[counter].value;
}
}
messageDetails.push(date_);
messageDetails.push(from_);
messageDetails.push(subject_);
messageDetails.push(msgID_);
return messageDetails;
}
function searchMessages(userId,condition)
{
//
// first we build the conditions
// we can make it fixed
// or we can make it dynamic
var searchResult;
var deleteResult;
var currentMessage;
var results = [];
var pageToken;
var params = {};
var _stat;
var options = {
includeSpamTrash: "true",
pageToken: pageToken
};
var msgRecord = [];
do
{
searchResult=Gmail.Users.Messages.list(userId,options);
for (var i = 0; i < searchResult.messages.length; i++)
{
var record=app.models.emailSearchResults.newRecord();
msgRecord=getMessageDetails(userId,searchResult.messages[i].id);
record.msgMainID=searchResult.messages[i].id;
record.msgID=msgRecord[3];
record.subject=msgRecord[2];
record.senderAddress=msgRecord[1];
record.msgDate=msgRecord[0];
/*console.log(searchResult.messages[i].id);
console.log(msgRecord[3]);
console.log(msgRecord[2]);
console.log(msgRecord[1]);
console.log(msgRecord[0]);
return;*/
results.push(record);
msgRecord=null;
}
if (searchResult.nextPageToken) {
options.pageToken = searchResult.nextPageToken;
}
} while (searchResult.pageToken);
searchResult=null;
return results;
}
On the main page I put a table and linked it to the datasource, and I enabled pagination on the table, so I get the pager buttons at the bottom of the table as below:
When I execute the app and the datasource is filled, I see the first page results in a correct way, however when I want to move to the next page, I click the next page button and once the loading is complete I find out that I still see the same results from the first page on the table.
I am not familiar with how to make the table show the results of the second page then the third page, and I am going in circles on this...
Hope the explanation is clear and addresses the issue..
I would really appreciate any help on this!

Currently pagination isn't working as expected with calculated datasources. You can, however, build your own. There are several changes you'll need to make to accomplish this. First you'll want to refactor your searchMessages function to something like this:
function searchMessages(userId, pageToken){
var results = [];
var options = {
includeSpamTrash: "true",
pageToken: pageToken,
maxResults: 50
};
var searchResult = Gmail.Users.Messages.list(userId, options);
for (var i = 0; i < searchResult.messages.length; i++){
var record = app.models.emailSearchResults.newRecord();
var msgRecord = getMessageDetails(userId,searchResult.messages[i].id);
record.msgMainID = searchResult.messages[i].id;
record.msgID = msgRecord[3];
record.subject = msgRecord[2];
record.senderAddress = msgRecord[1];
record.msgDate = msgRecord[0];
results.push(record);
}
return {records: results, nextPageToken: searchResult.nextPageToken};
}
Then you'll want to change your datasource query. You'll need to add a number parameter called page.
var cache = CacheService.getUserCache();
var page = query.parameters.page || 1;
var pageToken;
if(page > 1){
pageToken = cache.get('pageToken' + page.toString());
}
var results = searchMessages('me', pageToken);
var nextPage = (page + 1).toString();
cache.put('pageToken' + nextPage, results.nextPageToken);
return results.records;
You'll need to modify the pagination widget's various attributes. Here are the previous/next click functions:
Previous:
widget.datasource.query.pageIndex--;
widget.datasource.query.parameters.page = widget.datasource.query.pageIndex;
widget.datasource.load();
Next:
widget.datasource.query.pageIndex++;
widget.datasource.query.parameters.page = widget.datasource.query.pageIndex;
widget.datasource.load();
You should be able to take it from there.
I'm trying to change the radius category/type filter for a checkbox, so I changed the var type to an array.
ORIGINAL WORKING:
var type;
for (var i = 0; i < document.controls.type.length; i++){
if (document.controls.type[i].checked){
type = document.controls.type[i].value;
}
}
startBox.setBounds(map.getBounds());
var search = {
// keyword: 'comocomo', // not needed with the autocomplete / startBox
bounds: map.getBounds()
};
if (type != 'establishment'){
search.types = [ type ];
}
places.search(search, function(placesArr, status){
THE ONE WITH THE ARRAY NOT WORKING: edited:
var type=[];
for (var i = 0; i < document.controls.type.length; i++){
if (document.controls.type[i].checked){
type.push(document.controls.type[i].value)
}
}
startBox.setBounds(map.getBounds());
var search = {
bounds: map.getBounds()
};
var quotedAndCommaSeparated = "'" + type.join("','") + "'";
alert(quotedAndCommaSeparated); // 'establishment','restaurant','lodging'
search.types = [ quotedAndCommaSeparated ];
I made many tests, and I don't see what I'm doing wrong. the map doesn't even show.
What's this meant to be, doesn't look like valid Javascript to me:
var type[];
Should be
var type = [];
Fix the javascript errors in your code otherwise the map won't show up.
Update:
What you have in quotedAndCommaSeparated is a string like "'a','b','c'" that looks a bit like the contents of an array: ['a','b','c']. But it's not an array, it's just a single string. If you check the length of your search.type array, I'm guessing it equals 1.
What you can do is split your string on the comma to turn it into an array:
search.types = quotedAndCommaSeparated.split(",");
Scenario: I have a standard dropdown list and when the value in that dropdownlist changes I want to update another dropdownlist that exists in a tinyMCE control.
Currently it does what I want when I open the page (i.e. the first time)...
function changeParent() {
}
tinymce.create('tinymce.plugins.MoePlugin', {
createControl: function(n, cm) {
switch (n) {
case 'mylistbox':
var mlb = cm.createListBox('mylistbox', {
title: 'Inserts',
onselect: function(v) {
tinyMCE.execCommand("mceInsertContent",false,v);
}
});
<% foreach (var insert in (ViewData["Inserts"] as List<String>)) { %> // This is .NET
yourobject = '<%= insert %>'; // This is JS AND .NET
mlb.add(yourobject, yourobject); // This is JavaScript
<% } %>
// Return the new listbox instance
return mlb;
}
return null;
}
});
<%= Html.DropDownList(Model.Record[184].ModelEntity.ModelEntityId.ToString(), ViewData["Containers"] as SelectList, new { onchange = "changeParent(); return false;" })%>
I am thinking the way to accomplish this (in the ChangeParentFunction) is to call a controller action to get a new list, then grab the 'mylistbox' object and reassign it, but am unsure how to put it all together.
As far as updating the TinyMCE listbox goes, you can try using a tinymce.ui.NativeListBox instead of the standard tinymce.ui.ListBox. You can do this by setting the last argument to cm.createListBox to tinymce.ui.NativeListBox. This way, you'll have a regular old <select> that you can update as you normally would.
The downside is that it looks like you'll need to manually hook up your own onchange listener since NativeListBox maintains its own list of items internally.
EDIT:
I played around a bit with this last night and here's what I've come up with.
First, here's how to use a native list box and wire up our own onChange handler, the TinyMCE way:
// Create a NativeListBox so we can easily modify the contents of the list.
var mlb = cm.createListBox('mylistbox', {
title: 'Inserts'
}, tinymce.ui.NativeListBox);
// Set our own change handler.
mlb.onPostRender.add(function(t) {
tinymce.dom.Event.add(t.id, 'change', function(e) {
var v = e.target.options[e.target.selectedIndex].value;
tinyMCE.activeEditor.execCommand("mceInsertContent", false, v);
e.target.selectedIndex = 0;
});
});
As far as updating the list box at runtime, your idea of calling a controller action to get the new items is sound; I'm not familiar with ASP.NET, so I can't really help you there.
The ID of the <select> that TinyMCE creates takes the form editorId_controlId, where in your case controlId is "mylistbox". Firebug in Firefox is the easiest way to find the ID of the <select> :)
Here's the test button I added to my page to check if the above code was working:
<script type="text/javascript">
function doFoo() {
// Change "myEditor" below to the ID of your TinyMCE instance.
var insertsElem = document.getElementById("myEditor_mylistbox");
insertsElem.options.length = 1; // Remove all but the first option.
var optElem = document.createElement("option");
optElem.value = "1";
optElem.text = "Foo";
insertsElem.add(optElem, null);
optElem = document.createElement("option");
optElem.value = "2";
optElem.text = "Bar";
insertsElem.add(optElem, null);
}
</script>
<button onclick="doFoo();">FOO</button>
Hope this helps, or at least gets you started.
Step 1 - Provide a JsonResult in your controller
public JsonResult GetInserts(int containerId)
{
//some code to get list of inserts here
List<string> somedata = doSomeStuff();
return Json(somedata);
}
Step 2 - Create javascript function to get Json results
function getInserts() {
var params = {};
params.containerId = $("#184").val();
$.getJSON("GetInserts", params, updateInserts);
};
updateInserts = function(data) {
var insertsElem = document.getElementById("183_mylistbox");
insertsElem.options.length = 1; // Remove all but the first option.
var optElem = document.createElement("option");
for (var item in data) {
optElem = document.createElement("option");
optElem.value = item;
optElem.text = data[item];
try {
insertsElem.add(optElem, null); // standards compliant browsers
}
catch(ex) {
insertsElem.add(optElem, item+1); // IE only (second paramater is the items position in the list)
}
}
};
Step 3 - Create NativeListBox (code above provided by ZoogieZork above)
var mlb = cm.createListBox('mylistbox', {
title: 'Inserts'
}, tinymce.ui.NativeListBox);
// Set our own change handler.
mlb.onPostRender.add(function(t) {
tinymce.dom.Event.add(t.id, 'change', function(e) {
var v = e.target.options[e.target.selectedIndex].value;
tinyMCE.activeEditor.execCommand("mceInsertContent", false, v);
e.target.selectedIndex = 0;
});
});
//populate inserts on listbox create
getInserts();
