I have determined that my JSON, coming from the server, is valid (making the ajax call manually), but I would really like to use JQuery. I have also determined that the ‘post’ URL, being sent to the server, is correct, using firebug. However, the error callback is still being triggered (parse error). I also tried datatype: text.

Are there other options that I should include?

$(function() {     $('#submit').bind('click', function() {         $.ajax({             type: 'post',             url: 'http://myServer/cgi-bin/broker' ,             datatype: 'json',             data: {'start' : start,'end' : end},             error: function(request,error){                 alert(error);             },             success: function(request) {                 alert(request.length);             }         }); // End ajax     }); // End bind }); // End eventlistener

  1. Here are a few suggestions I would try:

    1) the ‘datatype’ option you have specified should be ‘dataType’ (case-sensitive I believe)

    2) try using the ‘contentType’ option as so:

    contentType: 'application/json; charset=utf-8'

    I’m not sure how much that will help as it’s used in the request to your post url, not in the response. See this article for more info: http://encosia.com/2008/06/05/3-mistakes-to-avoid-when-using-jquery-with-aspnet-ajax (It’s written for asp.net, but may be applicable)

    3) Triple check the output of your post url and run the output through a JSON validator just to be absolutely sure it’s valid and can be parsed into a JSON object. http://www.jsonlint.com

    Hope some of this helps!
