too long

Question

I need some help with JSON and jquery.

I developing application with dhtmlx scheduler. I want to create dhtmlx sections dynamically.

I generating json_encoded string using php json_encode function given in following

["{key:23, label:'T23 (34)'}","{key:24, label:'T24 (34)'}","{key:26, label:'T26 (26)'}","{key:35, label:'T35 (25)'}"]

Ajax call function for this

$.ajax({
            url:"updatetablestr.php",
            type:"get",
            data:{id:id},
            dataType: 'json',
            beforeSend:function(){},
            success:function(q)
            {
            var JSONString = JSON.stringify(q);
            var output=JSONString.replace(/\"/g,"");                
            scheduler.updateCollection("MyList",output);
            }
            })

PHP function is,

$resarray=json_encode($array);
echo preg_replace('/"([a-zA-Z]+[a-zA-Z0-9_]*)":/', '$1:', $resarray);

i removed first and last quotes using jquery

var JSONString = JSON.stringify(q);
var output =JSONString.replace(/\"/g,"");

after this jquery code i could get my output

[{key:23, label:'T23 (34)'}","{key:24, label:'T24 (34)'}","{key:26, label:'T26 (26)'}","{key:35, label:'T35 (25)'}]

This output is what i need. when i use static code like

 var output= [{key:23, label:'T23 (34)'}","{key:24, label:'T24 (34)'}","{key:26, label:'T26 (26)'}","{key:35, label:'T35 (25)'}]

is working . When i implement dynamically which generated php , JSON.stringify is not working.. that time its showing the following error

scheduler.updateCollection("MyList",output);

"Uncaught TypeError: Function.prototype.apply: Arguments list has wrong type" in dhtmlxschduler.js

While statically working with same string why it's not working when dynamically generated using php and jquery..
