Parse JSON from JQuery.ajax success data

I am having trouble getting the contents of JSON object from a JQery.ajax call. My call:

$('#Search').click(function () {
    var query = $('#query').valueOf();
    $.ajax({
        url: '/Products/Search',
        type: "POST",
        data: query,
        dataType: 'application/json; charset=utf-8',
        success: function (data) {
            alert(data);
            for (var x = 0; x < data.length; x++) {
                content = data[x].Id;
                content += "<br>";
                content += data[x].Name;
                content += "<br>";
                $(content).appendTo("#ProductList");
               // updateListing(data[x]);
            }
        }
    });
});

It seems that the JSON object is being returned correctly because "alert(data)" displays the following

[{"Id": "1", "Name": "Shirt"}, {"Id": "2", "Name":"Pants"}]

but when I try displaying the Id or Name to the page using:

content = data[x].Id;
content += "<br>";
content += data[x].Name;
content += "<br>";

it returns "undefined" to the page. What am I doing wrong?

Thanks for the help.

Solution 1:

The data is coming back as the string representation of the JSON and you aren't converting it back to a JavaScript object. Set the dataType to just 'json' to have it converted automatically.

Solution 2:

I recommend you use:

var returnedData = JSON.parse(response);

to convert the JSON string (if it is just text) to a JavaScript object.
