Hi I have the following JSON returned in a variable called data.

THIS IS THE JSON THAT GETS RETURNED...

[ {
       "Id": 10004, "PageName": "club"}, { "Id": 10040, "PageName": "qaz"}, { "Id": 10059, "PageName": "jjjjjjj"} ]

and I am trying to loop through the collection using $.each but I am running into problems where the alert is showing undefined. I have tried alot of different syntax but can't seem to figure this out.

The JQuery I am using is

$.each(data, function(i, item) { alert(item.PageName); });

Can any one point me in the right direction?

EDIT This is the code I am using to grab the data

$.getJSON('/Cms/GetPages/123', null, function(data) { fillSelect(data); });

and this is the function that gets called upon call back

function fillSelect(data) { alert(data); $.each(data, function(i, item) { alert(item.PageName); }); }

EDIT 2 This is slightly confusing me, according to the docs it should work as I have it, but it doesn't. According to fiddler the header shows:-

Content-Type: application/json; charset=utf-8

and the JSON is exactly correct above. I am using chrome if this makes any different. Will test in IE and FF....

EDIT 3

using $.get produces

"[\r\n {\r\n \"Id\": 10041,\r\n \"PageName\": \"01234567890\",\r\n \"MetaId\": 1000,\r\n \"TemplateId\": 2\r\n },\r\n {\r\n \"Id\": 10001,\r\n \"PageName\": \"about\",\r\n \"MetaId\": 1000,\r\n \"TemplateId\": 1\r\n },\r\n {\r\n \"Id\": 10056,\r\n \"PageName\": \"fdgdfgdfg\",\r\n \"MetaId\": 1000,\r\n \"TemplateId\": 1\r\n },\r\n {\r\n \"Id\": 10052,\r\n \"PageName\": \"hjkhjk\",\r\n \"MetaId\": 1000,\r\n \"TemplateId\": 2\r\n },\r\n {\r\n \"Id\": 10059,\r\n \"PageName\": \"jjjjjjj\",\r\n \"MetaId\": 1000,\r\n \"TemplateId\": 1\r\n },\r\n {\r\n \"Id\": 10057,\r\n \"PageName\": \"qqqqq\",\r\n \"MetaId\": 1000,\r\n \"TemplateId\": 2\r\n },\r\n {\r\n \"Id\": 10054,\r\n \"PageName\": \"qwqw\",\r\n \"MetaId\": 1000,\r\n \"TemplateId\": 2\r\n }\r\n]"

 

Answer:

var data = [ { "Id": 10004, "PageName": "club"}, { "Id": 10040, "PageName": "qaz"}, { "Id": 10059, "PageName": "jjjjjjj"} ]; $.each(data, function(i, item) { alert(data[i].PageName); }); $.each(data, function(i, item) { alert(item.PageName); });

these two options work well, unless you have something like:

var data.result = [ { "Id": 10004, "PageName": "club"}, { "Id": 10040, "PageName": "qaz"}, { "Id": 10059, "PageName": "jjjjjjj"} ]; $.each(data.result, function(i, item) { alert(data.result[i].PageName); });

EDIT:

try with this and describes what the result

$.get('/Cms/GetPages/123', function(data) { alert(data); });

FOR EDIT 3:

this corrects the problem, but not the idea to use "eval", you should see how are the response in '/Cms/GetPages/123'.

$.get('/Cms/GetPages/123', function(data) { $.each(eval(data.replace(/[\r\n]/, "")), function(i, item) { alert(item.PageName); }); });
