Why my jQuery function getJSON is not calling my function callback?


Why my jQuery function getJSON is not calling my function callback?

Does that help Your problem could be you might not be getting the expected result from the api call.
Add the fail event to the getJSON call and that will tell you what is wrong.
code :
 $.getJSON("@Url.Action("ListaCidade")/" + uf, listaCidadeCallBack)
 .fail(function( jqxhr, textStatus, error ) {
      console.log(error);
      var err = textStatus + ", " + error;
      alert("Request Failed: " + err );
 });
public ActionResult ListaCidade()
{
   var cidades = from c in ctx.Cidades
                          where c.Estado.ID == id
                          select c;
    return Json(cidades , JsonRequestBehavior.AllowGet);   
}

callback function doesn't work when using getJSON function in jQuery

Does that help I am trying to use the getJSON function in jQuery to import some data and trigger a callback function. The callback function doesn't run. However, if I try the same thing with the get function, it works fine. Strangely, it works with the get function even when I pass "json" as the type. Why is this happening? I tested the following file in Firefox 3 and IE 7: , The json needs to be valid, otherwise the callback will not fire.
jQuery getJSON never enters its callback function

help you fix your problem I've been sitting with this for hours now, and I cant understand why. , I think you might need to remove the
code :
nojsoncallback=1
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>
<script type="text/javascript">

var usedTagCount = 1;
var searchHits = 20;
var apiKey = "a68277b574f4529ace610c2c8386b0ba";


var searchAPI = "http://www.flickr.com/services/rest/?method=flickr.photos.search&" + 
                    "format=json&api_key=" + apiKey + "&sort=interestingness-desc&per_page="
                     + searchHits + "&jsoncallback=?&nojsoncallback=1&tags=";


var tagString = "";
var flickrImageData = new Array();


function search(query) {
tagString = query;


var q = searchAPI + tagString;


$.getJSON(q, function(data) {   


    $.each(data.photos.photo, function(i, item) {
            debugger;
            flickrImageData.push(item);                          
    });
});

}

search("cat");

</script>

it should still fix some issue The problem is not that it's invalid (as passing it though this site will confirm), it's that it's never "wrapped" in a callback method.
Look up JSONp.
code :
myCallback({"status":"OK","errorMessage":"","numberOfResults" ...);

it fixes the issue Is it possible that you're not returning well-formed JSON? That would cause jquery to not execute the callback code.
If you're sure you are (run it through a JSON Lint site to double check), make sure you're specifying Content-type: application/json in the header for the HTTP response
