jquery file upload - IE callback results in object

问题:

All, I know that there is this question already out there: jquery file upload - IE done callback data.result issue

However, I'm having the same issue and don't know how to resolve it. I had some working code that looked like this (based on the recommendation in the other post):

if($.fn.wl_File) $.fn.wl_File.defaults = {
    forceIframeTransport: true,
    onDone: function (e, data) {
    var result = jQuery.parseJSON(data.result);
    var filename = result[0].name;
    }
}

Which extracts the callback information perfectly in Firefox, Chrome etc except for IE. However, I still get an [object Object] back from IE. I get the following results back when I do a console.log(data.result) in Chrome:

[{
"name": "1_3266_671641333369_14800358_42187036_5237378_n.jpg",
"size": 35535,
"type": "image\/jpeg",
"url": "\/web\/upload\/1_3266_671641333369_14800358_42187036_5237378_n.jpg",
"thumbnail_url": "\/web\/upload\/thumbnails\/1_3266_671641333369_14800358_42187036_5237378_n.jpg",
"delete_url": "\/web\/upload.php?file=1_3266_671641333369_14800358_42187036_5237378_n.jpg",
"delete_type": "DELETE",
"upload_type": "video_montage",
"insert_id": "288"
}]

I don't know how to resolve the issue. Based on my code, can anyone point me in the right direction?

FYI, I'm using the following theme: http://revaxarts-themes.com/?t=whitelabel which calls the jquery upload plugin and that's why my code looks a little different at the top but it's basically the same thing as the plugin code.

Any help is greatly appreciated on this frustrating issue!

I found the solution to this from the post I mentioned in my question. However, I had to expand on it a little to satisfy the different browsers. The original answer was right about how to get the data from IE but that method didn't work for the other browsers. I had to add an if statement to see what my browser type was and proceed from there. My code to handle this scenario looks like the following:

if($.browser.msie){
    var data_to_parse = $( 'pre', data.result ).text();
}else{
    var data_to_parse = data.result;
}
var result = jQuery.parseJSON(data_to_parse);
var filename = result[0].name;

I can now manipulate the response I get from both IE and other browsers!

console.log in IE is not fantastic as in other browser, it is normal to output object Object. What you can do is start the developer tools (F12) and add a breakpoint in the line:

 var result = jQuery.parseJSON(data.result);
