Hello All!

 

It's been a while.

 

Trying to parse a json string and running into some issues.

<script type="text/javascript">    $().ready(function(){	var $_GET = {};	document.location.search.replace(/??(?[^=]+)=([^&]*)&?)/g, function () {    	    function decode(s) {                return decodeURIComponent(s.split("+").join(" "));    	    }    	    $_GET[decode(arguments[1])] = decode(arguments[2]);        });	//console.log($_GET["t"]);	$.get("assets/php/all_channels.php?t="+$_GET["t"],function(data){/*    START TROUBLE CODE*/	    $.each(data.channels, function(i,object){    	        $.each(object, function(property, value) {        	    console.log(property + "=" + value);    		});	    });/*    END TROUBLE CODE*/        });			    });</script>

In my chrome console I get the following:

Uncaught TypeError: Cannot read property 'length' of undefined 

I have tracked the issue down to my .each code because commenting it out eliminates the error. I have added comments to surround the troublesome code.

 

Any assistance with this issue is much appreciated.

what's data? are you logging your response to make sure it is what you expect it be? sounds like it's not an array.

oh i think i got it.

 

I didn't realize it was looking for an array (not sure why i didn't think of that)

 

I added

var json = jQuery.parseJSON(data);

the changed data.channels to json.channels.

 

now it seems to work.
