I understand JSON, but not JSONP. [Wikipedia&#39;s document on JSON][1] is (was) the top search result for JSONP. It says this:

&gt; JSONP or &quot;JSON with padding&quot; is a JSON extension wherein a prefix is specified as an input argument of the call itself.

Huh? What call? That doesn&#39;t make any sense to me. JSON is a data format. There&#39;s no call.

The [2nd search result][2] is from some guy named [Remy](https://stackoverflow.com/users/22617/remy-sharp), who writes this about JSONP:

&gt; JSONP is script tag injection, passing the response from the server in to a user specified function.

I can sort of understand that, but it&#39;s still not making any sense.

----

So what is JSONP? Why was it created (what problem does it solve)? And why would I use it? 

----

**Addendum**: I&#39;ve just created [a new page for JSONP][3] on Wikipedia; it now has a clear and thorough description of JSONP, based on [jvenema][4]&#39;s answer.

What is JSONP, and why was it created?

I&#39;m developing a page that pulls images from Flickr and Panoramio via jQuery&#39;s AJAX support.

The Flickr side is working fine, but when I try to `$.get(url, callback)` from Panoramio, I see an error in Chrome&#39;s console:

&gt; XMLHttpRequest cannot load http://www.panoramio.com/wapi/data/get_photos?v=1&amp;key=dummykey&amp;tag=test&amp;offset=0&amp;length=20&amp;callback=processImages&amp;minx=-30&amp;miny=0&amp;maxx=0&amp;maxy=150. Origin null is not allowed by Access-Control-Allow-Origin.

If I query that URL from a browser directly it works fine.  What is going on, and can I get around this?  Am I composing my query incorrectly, or is this something that Panoramio does to hinder what I&#39;m trying to do?

Google didn&#39;t turn up any useful matches on the [error message](http://www.google.co.uk/search?q=%22Origin+null+is+not+allowed+by+Access-Control-Allow-Origin%22).

**EDIT**

Here&#39;s some sample code that shows the problem:

    $().ready(function () {
      var url = &#39;http://www.panoramio.com/wapi/data/get_photos?v=1&amp;key=dummykey&amp;tag=test&amp;offset=0&amp;length=20&amp;callback=processImages&amp;minx=-30&amp;miny=0&amp;maxx=0&amp;maxy=150&#39;;
      
      $.get(url, function (jsonp) {
        var processImages = function (data) {
          alert(&#39;ok&#39;);
        };
        
        eval(jsonp);
      });
    });

You can [run the example online](http://jsfiddle.net/ZfvKm/).

**EDIT 2**

Thanks to Darin for his help with this.  **THE ABOVE CODE IS WRONG.**  Use this instead:

    $().ready(function () {
      var url = &#39;http://www.panoramio.com/wapi/data/get_photos?v=1&amp;key=dummykey&amp;tag=test&amp;offset=0&amp;length=20&amp;minx=-30&amp;miny=0&amp;maxx=0&amp;maxy=150&amp;callback=?&#39;;
      
      $.get(url, function (data) {
        // can use &#39;data&#39; in here...
      });
    });

I know `JSONP` is `JSON` with padding. 

I understand what JSON is, and how to use it with [`jQuery.getJSON()`][1]. However, I do not understand the concept of the `callback` when introducing JSONP.

Can anyone explain to me how this works?

Can anyone explain what JSONP is, in layman terms?

Format wise, file type wise and practical use wise?

How can you handle errors in a getJSON call? Im trying to reference a cross-domain script service using jsonp, how do you register an error method?

Please could someone help me work out how to get started with JSONP?

Code:

        var pm_url = &#39;http://twitter.com/status&#39;;
        pm_url += &#39;/user_timeline/stephenfry.json&#39;;
        pm_url += &#39;?count=10&amp;callback=photos&#39;;
        var photos = function (data) {
         alert(data);
        };
        $.ajax({
            url: pm_url,
            dataType: &#39;jsonp&#39;,
            jsonpCallback: &#39;photos&#39;,
            jsonp: false,
        });
    });

Fiddle: http://jsfiddle.net/R7EPt/6/

Should produce an alert, as far as I can work out from the documentation: isn&#39;t (but isn&#39;t producing any errors either).

thanks. 

Basic example of using .ajax() with JSONP?

Access-Control-Allow-Origin error sending a jQuery Post to Google API&#39;s

I am working on creating a new set of services in ASP.MVC MVC 4 using the Web API.  So far, it&#39;s great.  I have created the service and gotten it to work, and now I am trying to consume it using JQuery.  I can get back the JSON string using Fiddler, and it seems to be ok, but because the service exists on a separate site, trying to call it with JQuery errors with the &quot;Not Allowed&quot;.  So, this is clearly a case where I need to use JSONP.

I know that the Web API is new, but I&#39;m hoping someone out there can help me.

How do I make a call to a Web API method using JSONP?

JSONP with ASP.NET Web API

Can I make a cross-domain JSONP request in JavaScript without using jQuery or other external library? I would like to use JavaScript itself and then parse the data and make it an object so I could use it. Do I have to use an external library? If not, how can I do it?

How to make a JSONP request from Javascript without JQuery?

The following works in all browsers **except IE** (I&#39;m testing in IE 9).

    jQuery.support.cors = true;
    ...
    		$.ajax(
    			url + &quot;messages/postMessageReadByPersonEmail&quot;,
    			{
    				crossDomain: true,
    				data: {
    					messageId		: messageId,
    					personEmail		: personEmail
    				},
    				success: function() {
    					alert(&#39;marked as read&#39;);
    				},
    				error: function(a,b,c) {
    					alert(&#39;failed&#39;);
    				},
    				type: &#39;post&#39;
    			}
    		);

I have another function which uses `dataType: &#39;jsonp&#39;`, but I don&#39;t need any data returned on this AJAX call. My last resort will be to return some jibberish wrapped in JSONP just to make it work.

Any ideas why IE is screwing up with a CORS request that returns no data?

IE9 jQuery AJAX with CORS returns &quot;Access is denied&quot;

I have a webservice that when called without specifying a callback will return a JSON string using &lt;code&gt;application/json&lt;/code&gt; as the content type.

When a callback is specified it will wrap the JSON string in a callback function, so it&#39;s not really valid JSON anymore. My question is, should I serve it as &lt;code&gt;application/javascript&lt;/code&gt; in this case or still use &lt;code&gt;application/json&lt;/code&gt;?

Best content type to serve JSONP?

I am using angular&#39;s `$http.jsonp()` request which is successfully returning json wrapped in a function:

    var url = &quot;http://public-api.wordpress.com/rest/v1/sites/wtmpeachtest.wordpress.com/posts?callback=jsonp_callback&quot;;

    $http.jsonp(url).
		success(function(data, status, headers, config) {
			//what do I do here?
		}).
		error(function(data, status, headers, config) {
            $scope.error = true;
        });
    
How to access/parse the returned function-wrapped-JSON?

parsing JSONP $http.jsonp() response in angular.js

My WebAPI was deployed in the *Intranet* environment. That means *security* was not my concern.

It seems that CORS is *much more friendly* to the client and *easier to implement*.

Any other concerns I might have missed?



So, JSONP or CORS?

Is it possible to post data to JsonP? Or does all data have to be passed in the querystring as a GET request?

I have alot of data that I need to send to the service, cross domain, and it is too large to send via the querystring

What are the options for getting around this?

Post data to JsonP

To add some basic error handling, I wanted to rewrite a piece of code that used jQuery&#39;s $.getJSON to pull in some photo&#39;s from Flickr. The reason for doing this is that $.getJSON doesn&#39;t provide error handling or work with timeouts.

Since $.getJSON is just a wrapper around $.ajax I decided to rewrite the thing and surprise surprise, it works flawlessly.

Now the fun starts though. When I deliberately cause a 404 (by changing the URL) or cause the network to timeout (by not being hooked up to the interwebs), the error event doesn&#39;t fire, at all. I&#39;m at a loss as to what I&#39;m doing wrong. Help is much appreciated.

Here&#39;s the code:

    $(document).ready(function(){
    
        // var jsonFeed = &quot;http://api.flickr.com/services/feeds/photos_public.gne&quot;; // correct URL
        var jsonFeed = &quot;http://api.flickr.com/services/feeds/photos_public.gne_______&quot;; // this should throw a 404
    
        $.ajax({
            url: jsonFeed,
            data: { &quot;lang&quot; : &quot;en-us&quot;,
                    &quot;format&quot; : &quot;json&quot;,
                    &quot;tags&quot; : &quot;sunset&quot;
            },
            dataType: &quot;jsonp&quot;,
            jsonp: &quot;jsoncallback&quot;,
            timeout: 5000,
            success: function(data, status){
                $.each(data.items, function(i,item){
                    $(&quot;&lt;img&gt;&quot;).attr(&quot;src&quot;, (item.media.m).replace(&quot;_m.&quot;,&quot;_s.&quot;))
                              .attr(&quot;alt&quot;, item.title)
                              .appendTo(&quot;ul#flickr&quot;)
                              .wrap(&quot;&lt;li&gt;&lt;a href=\&quot;&quot; + item.link + &quot;\&quot;&gt;&lt;/a&gt;&lt;/li&gt;&quot;);
                    if (i == 9) return false;
                });
            },
            error: function(XHR, textStatus, errorThrown){
                alert(&quot;ERREUR: &quot; + textStatus);
                alert(&quot;ERREUR: &quot; + errorThrown);
            }
        });

    });


I&#39;d like to add that this question was asked when jQuery was at version 1.4.2

jQuery ajax (jsonp) ignores a timeout and doesn&#39;t fire the error event

Can you give a very simple example of reading a jsonp request with jquery? I just can&#39;t get it to work.

I&#39;m calling this function from my asp.net form and getting following error on firebug console while calling ajax.

CORS header &#39;Access-Control-Allow-Origin&#39; missing

I am using a JS object to create graphs with Google visualization. I am trying to design the data source. At first, I created a JS object client-side.  

```
var JSONObject = {
  cols: [{
      id: &#39;date&#39;,
      label: &#39;Date&#39;,
      type: &#39;date&#39;
    },
    {
      id: &#39;soldpencils&#39;,
      label: &#39;Sold Pencils&#39;,
      type: &#39;number&#39;
    },
    {
      id: &#39;soldpens&#39;,
      label: &#39;Sold Pens&#39;,
      type: &#39;number&#39;
    }
  ],
  rows: [{
      c: [{
        v: new Date(2008, 1, 1),
        f: &#39;2/1/2008&#39;
      }, {
        v: 30000
      }, {
        v: 40645
      }]
    },
    {
      c: [{
        v: new Date(2008, 1, 2),
        f: &#39;2/2/2008&#39;
      }, {
        v: 14045
      }, {
        v: 20374
      }]
    },
    {
      c: [{
        v: new Date(2008, 1, 3),
        f: &#39;2/3/2008&#39;
      }, {
        v: 55022
      }, {
        v: 50766
      }]
    }
  ]
};

var data = new google.visualization.DataTable(JSONObject, 0.5);
```

Now I need to fetch the data dynamically. So I send an AJAX request to a page that returns the JSON string:
 
     &quot;cols: [{id: &#39;date&#39;, label: &#39;Date&#39;, type: &#39;date&#39;},
    {id: &#39;soldpencils&#39;, label: &#39;Sold Pencils&#39;, type: &#39;number&#39;},
    {id: &#39;soldpens&#39;, label: &#39;Sold Pens&#39;, type: &#39;number&#39;}],
      rows: [{c:[{v: new Date(2008,1,1),f:&#39;2/1/2008&#39;},{v: 30000}, {v: 40645}]},
          {c:[{v: new Date(2008,1,2),f:&#39;2/2/2008&#39;},{v: 14045}, {v: 20374}]},
    {c:[{v: new Date(2008,1,3),f:&#39;2/3/2008&#39;},{v: 55022}, {v: 50766}]}&quot;

This I save into a variable:

    var var1 = &quot;cols: [{i ....... 66}]}&quot;

and show as 

    alert(var1);

Now my task is to create a JS object from this string. This is not working. When I use a JS object, everything works fine and I am able to get my required graph. Now if I try putting the same value of string from the AJAX request which I confirmed from a alert message into a n object, the object is not getting created correctly. Please let me know your opinion and any correction or advices.


JSON string to JS object

Is it possible to catch an error when using JSONP with jQuery? I&#39;ve tried both the $.getJSON and $.ajax methods but neither will catch the 404 error I&#39;m testing. Here is what I&#39;ve tried (keep in mind that these all work successfully, but I want to handle the case when it fails):

    jQuery.ajax({
        type: &quot;GET&quot;,
        url: handlerURL,
        dataType: &quot;jsonp&quot;,
        success: function(results){
            alert(&quot;Success!&quot;);
        },
        error: function(XMLHttpRequest, textStatus, errorThrown){
            alert(&quot;Error&quot;);
        }
    });

And also:

    jQuery.getJSON(handlerURL + &quot;&amp;callback=?&quot;, 
        function(jsonResult){
            alert(&quot;Success!&quot;);
        });

I&#39;ve also tried adding the $.ajaxError but that didn&#39;t work either:

    jQuery(document).ajaxError(function(event, request, settings){
       alert(&quot;Error&quot;);
    });

Thanks in advance for any replies!

How do I catch jQuery $.getJSON (or $.ajax with datatype set to &#39;jsonp&#39;) error when using JSONP?

I am looking to return some JSON across domains and I understand that the way to do this is through JSONP rather than pure JSON. &lt;br /&gt;
I am using ASP.net MVC so I was thinking about just extending the `JsonResult` type and then extending the Controller so that it also implemented a Jsonp method. &lt;br/&gt;
Is this the best way to go about it or is there a built-in `ActionResult` that might be better?

&lt;hr /&gt;

**Solution**:  I went ahead and did that.  Just for reference sake I added a new result:

````
public class JsonpResult : System.Web.Mvc.JsonResult
{
    public override void ExecuteResult(ControllerContext context)
    {
        if (context == null)
        {
            throw new ArgumentNullException(&quot;context&quot;);
        }

        HttpResponseBase response = context.HttpContext.Response;

        if (!String.IsNullOrEmpty(ContentType))
        {
            response.ContentType = ContentType;
        }
        else
        {
            response.ContentType = &quot;application/javascript&quot;;
        }
        if (ContentEncoding != null)
        {
            response.ContentEncoding = ContentEncoding;
        }
        if (Data != null)
        {
            // The JavaScriptSerializer type was marked as obsolete prior to .NET Framework 3.5 SP1
        #pragma warning disable 0618
            HttpRequestBase request = context.HttpContext.Request;

            JavaScriptSerializer serializer = new JavaScriptSerializer();
            response.Write(request.Params[&quot;jsoncallback&quot;] + &quot;(&quot; + serializer.Serialize(Data) + &quot;)&quot;);
        #pragma warning restore 0618
        }
    }
}
````

and also a couple of methods to a superclass of all my controllers:

 
````
protected internal JsonpResult Jsonp(object data)
{
    return Jsonp(data, null /* contentType */);
}

protected internal JsonpResult Jsonp(object data, string contentType)
{
    return Jsonp(data, contentType, null);
}

protected internal virtual JsonpResult Jsonp(object data, string contentType, Encoding contentEncoding)
{
    return new JsonpResult
    {
        Data = data,
        ContentType = contentType,
        ContentEncoding = contentEncoding
    };
}

Works like a charm.  

ASP.net MVC returning JSONP

Are there any security issues that should be considered when using JSONP?



Is JSONP safe to use?

I know about AJAX cross-domain policy.
So I can&#39;t just call &quot;http://www.google.com&quot; over a ajax HTTP request and display
the results somewhere on my site.

I tried it with dataType &quot;jsonp&quot;, that actually would work, but I get a syntax error (obviously because the received data is not JSON formated)

Is there any other possiblity to receive/display data from a foreign domain?
iFrames follow the same policy?


AJAX cross domain call

I am using jQuery Version 1.5.1 to do the following ajax call:

    $.ajax({
        dataType: &#39;jsonp&#39;,
        data: { api_key : apiKey },
        url: &quot;http://de.dawanda.com/api/v1/&quot; + resource + &quot;.json&quot;,
        success: function(data) { console.log(data); },
        error: function(jqXHR, textStatus, errorThrown) { console.log(errorThrown); console.log(textStatus); }
    });

The server responds with a valid json object:

    {
      &quot;response&quot;: {
        &quot;type&quot;:&quot;category&quot;,
        &quot;entries&quot;:1,
        &quot;params&quot;:{
          &quot;format&quot;:&quot;json&quot;,
          &quot;api_key&quot;:&quot;c9f11509529b219766a3d301d9c988ae9f6f67fb&quot;,
          &quot;id&quot;:&quot;406&quot;,
          &quot;callback&quot;:&quot;jQuery15109935275333671539_1300495251986&quot;,
          &quot;_&quot;:&quot;1300495252693&quot;
        },
        &quot;pages&quot;:1,
        &quot;result&quot;:{
          &quot;category&quot;:{
            &quot;product_count&quot;:0,
            &quot;id&quot;:406,
            &quot;restful_path&quot;:&quot;/categories/406&quot;,
            &quot;parent_id&quot;:null,
            &quot;name&quot;:&quot;Oberteile&quot;
           }
         }
       }
     }

But the success callback is never called, instead the error callback produces this output:

    jQuery15109935275333671539_1300495251986 was not called
    parsererror

Why does this happen?

I am using no additional libraries to jQuery.

**EDIT:** 

If I try to make the ajax call with &quot;json&quot; as dataType instead of &quot;jsonp&quot;, the server responds with an empty string.

parsererror after jQuery.ajax request with jsonp content type

I am using JQuery ajax jsonp. I have got below **JQuery Code:**

     $.ajax({  
            type:&quot;GET&quot;,        
            url: &quot;Login.aspx&quot;,  // Send the login info to this page
            data: str, 
            dataType: &quot;jsonp&quot;, 
            timeout: 200000,
            jsonp:&quot;skywardDetails&quot;,
            success: function(result)
            { 
                 // Show &#39;Submit&#39; Button
                $(&#39;#loginButton&#39;).show();
    
                // Hide Gif Spinning Rotator
                $(&#39;#ajaxloading&#39;).hide();  
             } 
           
        });  

The above code is working fine, I just want to send the request as **&quot;POST&quot;** instead of **&quot;GET&quot;**, Please suggest how can I achieve this.

Thanks           

How to use type: &quot;POST&quot; in jsonp ajax call

I am facing the same-origin policy problem, and by researching the subject, I found that the best way for my particular project would be to use JSONP to do cross-origin requests.

I&#39;ve been reading [this article from IBM about JSONP][1], however I am not 100% clear on what is going on.

All I am asking for here, is a simple jQuery&gt;PHP JSONP request (or whatever the terminology may be ;) ) - something like this **(obviously it is incorrect, its just so you can get an idea of what I am trying to achieve :) )**:

jQuery:

    $.post(&#39;http://MySite.com/MyHandler.php&#39;,{firstname:&#39;Jeff&#39;},function(res){
        alert(&#39;Your name is &#39;+res);
    });

PHP:

    &lt;?php
      $fname = $_POST[&#39;firstname&#39;];
      if($fname==&#39;Jeff&#39;)
      {
        echo &#39;Jeff Hansen&#39;;
      }
    ?&gt;

How would I go about converting this into a proper JSONP request? And if I were to store HTML in the result to be returned, would that work too?

How to solve JSON_ERROR_UTF8 error in php json_decode?

I had a JSON string / object in my application. 

    {&quot;list&quot;: [
        {&quot;name&quot;:&quot;my Name&quot;,&quot;id&quot;:12,&quot;type&quot;:&quot;car owner&quot;},
        {&quot;name&quot;:&quot;my Name2&quot;,&quot;id&quot;:13,&quot;type&quot;:&quot;car owner2&quot;},
        {&quot;name&quot;:&quot;my Name4&quot;,&quot;id&quot;:14,&quot;type&quot;:&quot;car owner3&quot;},
        {&quot;name&quot;:&quot;my Name4&quot;,&quot;id&quot;:15,&quot;type&quot;:&quot;car owner5&quot;}
    ]}

I had a filter box in my application, and when I type a name into that box, we have to filter the object and display the result.

For example, if the user types &quot;name&quot; and hits search, then we have to search full names in the JSON object and return the array, just like a MySQL search ...

My question is to filter the json object with string and return the array....

&lt;!--Please help--&gt;
