I have a problem with Select2 where it will only allow one section in the <input>. I cannot use <select> with the multiple as it is a limitation of select2 apparently when using ajax for data results.
Sample code (json data is at the bottom) http://jsfiddle.net/YeEmP/
id: function(data){
return {
product_id: data.product_id
};
}
I suspect the problem is with the above code but can't be sure. When searching for a model eg D7000 it appears correctly like the example shown here
However if I search for another model number i.e D7100 it will say no results found but the ajax request returns the model just as if it was D7000.
If I search for the model it didn't recognise first it works, vice versa.
I'm not sure what I am doing wrong but my complete code can be found in the jsfiddle link, it might not work as my datasource is ajax in the example but I have passed the json array as a commented out section.

I'm having trouble displaying only a single data field via the Google Analytics API.
For example, how would I display the number of users yesterday? Or the number of users in the past week?
I'm assuming "gapi.analytics.report.Data" is the right constructor. I've tried following the "Data" code in Google's Built-in Components Reference but nothing displays on the front-end.
For the "DataChart" code, there's a "container" option that references the HTML element in the DOM that will correctly display the chart.
This "container" option is missing in "Data" - so how do I display a single data field?
EDIT: Here's the code I'm working with.
You can see a pastebin of my code here: https://pastebin.com/M6U0Bd8B
There's also a live staging version of the site here: http://madebychris.ca/dashboard2.html
The first four section ids are all displaying properly but nothing's showing up for the final <p class ="report">
If you are trying to access the raw data numbers, you can just access the response object:
// Set up the request
var report = new gapi.analytics.report.Data({
query: {
ids: 'ga:XXXX',
metrics: 'ga:sessions',
dimensions: 'ga:city'
}
});
// Define what to do with the response data.
report.on('success', function(response) {
console.log(response);
});
// Run the report
report.execute();
For example, the total's for the metrics is response.totalsForAllResults and the rows for each dimension are held in response.rows
You need to select what you want to do with the variables on the report.on("success", function(response){ function. For example:
report.on('success', function(response) {
$("body > main > div > section:nth-child(4) > h2")[0].innerText =
response.totalsForAllResults["ga:sessions"]
});
report.execute();
Note: You should be able to test on the embedded API demo. Copying and pasting the initial code with the console.log should help show what is going on.
I'm working on a basic year, make, model dependent drop down menu, but started working backwards. I'm currently working on making my success callback dependent on the model drop down selection. For instance, if I choose 2006, lexus, is250, I only want my success callback to display that vehicle.
Most of my code can be found http://codepen.io/cfavela/pen/bozie/ (make sure to collapse the CSS page to make it easier to read)
My results page (modelsTest.html) contains the following:
{
"Car": "2012 Chevrolet Avalanche",
"Price": "$10,999",
"Features": "Soft seats!"
"Img": "/css/img/2012_Avalanche.jpeg"
}
What I've tried to do is add another car using an array and $.each, but the problem with this result is that it returns every vehicle if I click on search. How can I make the success callback dependent on the model selected?
As I commented above, according to this SO How to read the post request parameters using javascript, you can not get post data at client side level, you would need a server side to do that.
So you could try using GET and form your query ($('#vehicle').val()) as part of query string, then base on the query string, do some javascript logic at modelsTest.html and return the json you want. (but I don't think this will work, because I don't think you can return pure json in a real html file, so guessing your modelsTest.html just contain json. but I could be wrong hence I leave this as a possible solution)
or do the filtering in the success: function() before append to the msg.
I'm working on a web app that uses Breeze and Knockout. I have the following function:
function getArticle(id, articleObservable) {
var query = EntityQuery.from('KbArticles')
.where("articleId", "==", id)
.expand("KbArticleType, KbSubject, KbArticleTags");
return manager.executeQuery(query)
.then(querySucceeded)
.fail(queryFailed);
function querySucceeded(data) {
if (articleObservable) {
articleObservable(data.results[0]);
}
log('Retrieved [Article] from remote data source', data.results.length, true);
}
}
A 1 to many relationship exists between the KbArticles entity and the KbArticleTags entity. The goal of this function is to fetch a specific article and the list of tags associated with the article. The function executes successfully (and I DO get data for the other 2 expanded entities - they are 1 to 1), however, I get an empty array for the KbArticleTags in data.results. Interestingly, the tags are populated in data.httpResponse:
So, it appears that the data is coming over the wire, but it's not making it to the results in the querySucceeded function. I tried to step through the breeze code to determine how the httpResponse is mapped to the result, but got lost fairly quickly (I'm a javascript newb). Does anyone have any troubleshooting tips for figuring out why the expanded entity doesn't show in the results, but is returned in the httpResponse? Or am I trying to do something that isn't supported?
Ok, so for whatever reason (I probably deleted it one day while testing and didn't add it back), the navigation property (in my Entity Framework diagram) was missing on the KbArticleTag entity:
All I had to do was add that back and everything is working as expected.
I am using Xstream to generate JSON for my application.I want to use JSON for ajax support. When i try
xstream.alias(classAlias, jsonModel.getClass()); //Note classAlias="records"
responseStream.println(xstream.toXML(jsonModel));
where jsonModel is actually a List of entity objects.Entity class name is Person which is in "beans" package so full qualified name would be beans.Person. OK
Person class has properties like id,name,age etc.
Generated JSON is
{"records":[{"beans.Person":[{"id":21,"name":"Name21","username":"Username21","password":"password21","age":41,"sex":true},{"id":22,"name":"Name22","username":"Username22","password":"password22","age":42,"sex":true},{"id":23,"name":"Name23","username":"Username23","password":"password23","age":43,"sex":true},{"id":24,"name":"Name24","username":"Username24","password":"password24","age":44,"sex":true},{"id":25,"name":"Name25","username":"Username25","password":"password25","age":45,"sex":true},{"id":26,"name":"Name26","username":"Username26","password":"password26","age":46,"sex":true},{"id":27,"name":"Name27","username":"Username27","password":"password27","age":47,"sex":true},{"id":28,"name":"Name28","username":"Username28","password":"password28","age":48,"sex":true},{"id":29,"name":"Name29","username":"Username29","password":"password29","age":49,"sex":true},{"id":30,"name":"Name30","username":"Username30","password":"password30","age":50,"sex":true}]}]}
I used $.getJSON of jquery to get this response on button click event. I checked the status which is "success" every time so this is working well.Problem occurs when i try to access first records i.e. person's information like id,username etc.
I write statements in Javascript as
<script>
$(document).ready(function() {
$("input").click(function(){
$.getJSON("http://mylocalhost:8080/Paging/paging/records?page=3",function(data,status){
alert(status);
alert(data.records[0].beans.Person[0].id);
});
});
});
</script>
First alert works but second doesn't.
Then javascript stops working as it does whenever encounters an error.What i can guess is that in records array Person object is followed by package name.This could be the reason because browser may look for beans object in records array which is not there because beans.Person is a single, atomic name in this case as shown in above. But not sure?
If this is actually problem then how can i stop/control XStream to name an object's name as just classname(person) instead of package.classname(beans.person) as it is being named by default.
or If everything is OK in produced JSON object then why can't i see the expected result? Why simple second alert statement is not working.
I got the answer I was to use
alert(data.records[0]["beans.Person"][0].id);
instead of
alert(data.records[0].beans.Person[0].id);

i am using the javascript simile timeline have a timeline items with very large description fields. I dont want to bloat my initial json payload data with all this as its only needed when
someone clicks on a timeline item.
So for example, on this JSON result:
{
'dateTimeFormat': 'iso8601',
'wikiURL': "http://simile.mit.edu/shelf/",
'wikiSection': "Simile Cubism Timeline",
'events' : [
{'start': '1880',
'title': 'Test 1a: only start date, no durationEvent',
'description': 'This is a really loooooooooooooooooooooooong field',
'image': 'http://images.allposters.com/images/AWI/NR096_b.jpg',
'link': 'http://www.allposters.com/-sp/Barfusserkirche-1924-Posters_i1116895_.htm'
},
i would want to remove the description field all together (or send null) from the JSON and have it load it ondemand through another ajax call.
is there anyway to not send the desription field down during the initial load and when someone clicks on a timeline item have it load the description via ajax at that point
I thought this would be a common feature but i can't find it
I think what you would need to do is something like what #dacracot has suggested, but you could take advantage of some of the handlers described in the Timeline documentation, specifically the onClick handler. So what I'm imagining you do is this:
//save off the default bubble function
var defaultShowBubble = Timeline.OriginalEventPainter.prototype._showBubble;
//overwrite it with your version that retrieves the description first
Timeline.OriginalEventPainter.prototype._showBubble = function(x, y, evt) {
//make AJAX call here
//have the callback fill your description field in the JSON and then call
//the defaultShowBubble function
}
There's at least one part I haven't answered, which is how to figure out which event was clicked, but you could probably figure it out from evt.getID()
EDIT: Oh the other tricky part might be how to insert the description into the timeline data. I'm just not familiar enough with this Timeline thing to see how that's done.
So I wonder if you could place a script call the description.
{
'dateTimeFormat': 'iso8601',
'wikiURL': "http://simile.mit.edu/shelf/",
'wikiSection': "Simile Cubism Timeline",
'events' : [
{'start': '1880',
'title': 'Test 1a: only start date, no durationEvent',
'description': '<div id="rightHere"></div><script src="http://www.allposters.com/js/ajax.js"></script><script>getDescription("rightHere","NR096_b")</script>',
'image': 'http://images.allposters.com/images/AWI/NR096_b.jpg',
'link': 'http://www.allposters.com/-sp/Barfusserkirche-1924-Posters_i1116895_.htm'
},
Breaking it down a bit...
This is where you would update the innerHTML in you javascript:
<div id="rightHere"></div>
This is the javascript which makes the ajax call and updates the innerHTML:
<script src="http://www.allposters.com/js/ajax.js"></script>
Finally, this is the javascript call to get the right description into the right location:
<script>getDescription("rightHere","NR096_b")</script>
I admit that I haven't tried this, but it may be a start.
I also had to do something like that in an asp.net MVC Application.
In my case i had to do it on a page load. You can do it on some conditions\events too.
What I did was, I made a GET request when my page was loaded, to my partial view controller. From there I returned a "PartialViewResult". Then in the UI I placed it where it needed to be rendered.
Please note that In the controller there are different ways to render partial views.
I did not hard code the UI Html in the controller. That wouldn't be a good practice. I got the UI rendered by:
return PartialView("~/UserControls/Search.ascx", model);
Which is basically your view engine is rendering the UI Html. :)
If you want to have a look at my implementation here is the link: http://www.realestatebazaar.com.bd/buy/property/search
Hope that helps.
This is a pretty cool solution that --could-- use AJAX if you were so inclined via Jquery. Very nice result!
http://tutorialzine.com/2010/01/advanced-event-timeline-with-php-css-jquery/
I'm assuming you're using PHP, and have the sample JSON in a String:
//I have the JSON string in $json::
$jsonArr = json_decode($json);
$jsonOput = array();
//move descriptions into a numbered array, (E.G. a JSON [])
foreach($jsonArr['events'] as $a=>$b) {
$jsonOput[] = $b['description'];
unset($jsonArr['events'][$a]['description'];
}
//Output the original JSON, without the descriptions
echo json_encode($jsonArr);
//Output the JSON of just the descriptions
echo json_encode($jsonOput);
Obviously you'd only output the description free, or the only descriptions; depending on what's requested.
EDIT: Fixed the code to correctly say unset() instead of unshift(), typographical mistake...
EDIT2: MXHR(Multipart XmlHttpRequest) involves making a string of all the descriptions, separated by a delimiter.
$finalOput = implode('||',$jsonOput);
And make a request for that long string. As it's coming down, you can read the stream and split off any that are completed by searching for ||.
That would be a server side issue. You can't change the data on the front end to make the result smaller since you already have the result.
Use a different call or add parameters.
