Json Help

I am having some problems with JSON.

So i have a URL which is outputting JSON code. I need to parse this into a usable object.

So far i have done this:

var jsonURL = "http://www.thejasoncode.com/JSONGenerator?cid=20000&parameter1=something&pparameter2=something&callback=callbackresults

var myObject = eval('(' + jsonURL + ')');
div.innerHTML = typeof(myObject);
		
return div;

I am trying to verify that it is returning an object by using typeof(). Firefox error console is telling me that

Error: missing ) in parenthetical
Source File: source file
Line: 21, Column: 5
Source Code:
here it shows the URL and an arrow pointing to ":" after http.

any ideas of help appreciated

Could just be the forum, or the cut and paste job, but I don't see a close quote, or semi colon on the first JS line there, where you define the jsonURL. I'm no JS guru, but open ended quotes can often create misleading errors...

I have still not actually solved this problem as yet. Please someone tell me that this damn json is worth all the headache.

I cannot get the JSON callback function to work unless i explicitly write the include and the callback function directly on the page.

For example.

I want to use all the data from the JSON callback function to create elements to put on the page. This means i want to just include a file that does all this.

If i include a javascript file that has my callback function and the included external URL JSON object it just does not work.

expample.....

<html>
<head></head>
<body>
<script src="myjsonstuff.js" type="text/javascript"></script>
</body>
</html>

But when i explicitly write the damn thing on the page it does work.

example....

<html>
<head></head>
<body>
<script>
function jsonresults(obj){
  jsonvariable = obj.somejson.so[0].ti;
</script>
<script src="http;//www.json.php?parm=5&param=4&callback=jsonresults" type="text/javascript"></script>
</body>
</html>

can someone please advise me how i can get this working. It just seems to ridiculous too be true.

You've confirmed that the file 'myjsonstuff.js' is web accessible in the context/path you've given in the include?

Cheers,
