$.getJSON not working in Internet Explorer

问题

I am using following code to grab data from JSON.

 $(document).ready(function()
 {
   $.getJSON("http://www.example.com/data.php?id=113&out=json", function(data) {

        $.each(data.issue.page, function(i,item) {
            imagesJSON[i] = item["@attributes"];
        });

       alert(imagesJSON.length);
    });
 });

It works in Mozilla, Chrome and other browser but not in IE. (Not in any Version).

回答1:

$.getJSON has a tendency to cache results in IE. Use $.ajax instead.

The related call should be something like this in your case:

// Not really sure if you've forgot to var 
var imagesJSON = [];

$.ajax({
  url: "www.example.com/data.php?id=113&out=json",
  cache: false,
  dataType: "json",
  success: function(data) {
    $.each(data.issue.page, function(i,item) {
        imagesJSON[i] = item["@attributes"];
    });

    alert(imagesJSON.length);
  },
  error: function (request, status, error) { alert(status + ", " + error); }
});

Make sure you have cache: false.

UPDATE:

It appears to be a configuration issue at the host with the request url that the OP actually uses. Going to the url directly with IE web browser results in an abort from the host. You can't do much than to report the issue to the host, like an email to the webmaster of the host.

I had the same error on a page, and I added these lines :

<!--[if lte IE 9]>
<script type='text/javascript' src='//cdnjs.cloudflare.com/ajax/libs/jquery-ajaxtransport-xdomainrequest/1.0.0/jquery.xdomainrequest.min.js'></script>
<![endif]-->

and it finaly works for me ;) no more error for IE9

This post helps me jQuery Call to WebService returns "No Transport" error
