Question

Why does this not work? anybody:

In my code I have:

$.getJSON("http://isp123.co.uk/cw/NorthWales/Test.txt?jsoncallback=?",
        function(data){
                //This never gets executed
            alert('here');
          });

The text file can be viewed here:

This is not a JSONP response:

({"name" : "hello world"});

If you had a proper JSONP response, then your code should work.

The question mark in the “callback=?” part of the URL is changed by jQuery before making the request, your JSONP server needs to be able to dynamically create the JSONP “function” in response to the unique jQuery request. If you can’t dynamically create your JSONP, perhaps you could use YQL/Yahoo pipes to turn it into JSONP?

This pipe should do the trick, to see if it works, use this URL instead in your getJSON function: http://pipes.yahoo.com/pipes/pipe.run?u=http%3A%2F%2Fisp123.co.uk%2Fcw%2FNorthWales%2FTest.txt&_id=332d9216d8910ba39e6c2577fd321a6a&_render=json&_callback=?

I just tried this and it worked:

$.getJSON("http://pipes.yahoo.com/pipes/pipe.run?u=http%3A%2F%2Fisp123.co.uk%2Fcw%2FNorthWales%2FTest.txt&_id=332d9216d8910ba39e6c2577fd321a6a&_render=json&_callback=?", function(data){
    //This always gets executed!!!
    alert('here');
});
