jquery ajax web method works but unable to use data

Question

My web service call returns this into data1

"{"d":"PCIS Follow Add ID and Codes when printed"}"

I learne that when using jquery with asp.net i must use data1.d

however when i try to do alert(data.d);

i get undefined returned even though data.d value shows as

"{"d":"PCIS Follow Add ID and Codes when printed"}"

any ideas on how i can use this information

the web service should be returning a string

 $.ajax({
                type: "POST",
                url: "Services/WorkService.asmx/WorkDescription",
                data: "{'workUnitId' : '" + $("option:selected", $(dropdown)).text() + "','id': '" + combobox.val() + "'}",
                contentType: "application/json; charset=utf-8",
                dataType:"json",
                success: function(data1) {
                var jsObject = JSON.parse(data1.d);
            alert(jsObject);                   
 combobox.attr("_tooltip", data1.d);    
                }    
            });
        },

will be better if you post us your webservice call using jquery — Devjosh, Feb 02 '12 at 16:36
please check your json string returned by the webservice call using http://www.jsonlint.com or any other json validator. you can find the json in mozilla firebug net panels xhr tab — Devjosh, Feb 02 '12 at 16:42
check if adding `?workUnitId=...` will help, it could be server issue — vittore, Feb 02 '12 at 16:43
@JamesMcLaughlin yes, because if you specify the dataType jQuery "believes" you and doesn't try to "guess" the format of the response — Nicola Peluchetti, Feb 02 '12 at 16:47

you should set json as dataType

 dataType:"json",

because if you specify text jQuery won't parse the response (if you specify json jQuery calls $.parseJSON() on the response)

Look at my answer in this question Why is 'jQuery.parseJSON' not necessary?

EDIT your server should return

{"d":"PCIS Follow Add ID and Codes when printed"}

withouth the starting and trailing "

problem is i just changed it to text it was json before and wasnt working – HELP_ME Feb 02 '12 at 16:46
@bugz if you just call `alert(data1)` what do you get? – Nicola Peluchetti Feb 02 '12 at 16:48
@bugz i edited my answer, maybe before it didn't work because it wasn't valid json – Nicola Peluchetti Feb 02 '12 at 16:50
i get [object Object] this is after i switched my dataType to json Normal I should use data1.d – HELP_ME Feb 02 '12 at 16:50
@bugz if you get [object Object] it is correct, if you use Chrome (or Firefox with firebug) you could do `console.log(data1)` and see post here what you see in your "console" panel – Nicola Peluchetti Feb 02 '12 at 16:52

Try this:

<script>
var jsObject = JSON.parse('{"hello":"world"}');
alert(jsObject.hello);
</script>
