This is 99.9% of the time a bug in your code and not a bug in jQuery. What helps is using the development version of jQuery. It is not minified, which means that it still has the full variable names instead of a, b, etc. Did you send a: header('Content-Type: application/json'); before the echo json_encode($data);? That would triggers jQuery's JSON detection. Add a console.log(data); before the $.each to confir

The problem I am having is that I am getting a TypeError: a is undefined, and I have no idea why. Here is my code: jQuery function $("#clickjson").click(function () { $.getJSON("gmessagegroup.php?gid=" + $('#gbox').val(), function (data) { $.each(data.messages, function (key, val) { if (data.messages[key].clientmessageid != undefined) { console.log(data.messages[key].clientmessageid + ":" + data.messages[key].from + " - " + data.messages[key].content); $("#messages tbody tr:last").after('

The tabcordion javascript file is being 'enqueued' and appearing after the jquery file (so that bit looks ok). The start of the jquery code is: (function($) { var Tabcordion; $.fn.tabcordion = function(option) { return this.each(function() { var $this, data, options; a is undefined $this = $(this); // rest of code .... When I load my page I get the error "TypeError: $ is undefined" in Firebug After a bit of googling I changed all the $. into jQuery. That sorts some of the issues out but I then get an error about the line: $this = $(this); I'm assuming that I don't have $ defined for jquery. I tried adding a line at the top of the function: $ = jQuery; but that didn't work. Any ideas how I can get the $ to behave? I have another script that works that is enclosed by: (function($){ jQuery(document).ready(function($){ // code in here }); })(jQuery); But the end of tabcordion has: (function($) { // tabcordion code.... }).call(this); And the "call(this)" bit is throwing me? Any ideas? javascript jquery wordpress share|improve this question asked Feb 9 '14 at 14:32 John T 4392714 just change your $ to jQuery and it'll work if you have already loaded jquery –Amit Garg Feb 9 '14 at 14:55 @AmitGarg: It's not the OP's code where the problem lies. It's tabcordian. –T.J. Crowder Feb 9 '14 at 15
