Jquery.Ajax（）成功后无法获取数据/响应

Question

Hi people, I am craving myself from past 3 days and I just couldn't find the way to access json response seen on my browser

Here is my Ajax code :

$("[id*=btnModalPopup]").live("click", function () {

    $("#tblCustomers tbody tr").remove();

    $.ajax({
        type: "POST",
        url: "CallDataThroughJquery.aspx/GetLeadDetails",
        data: '{}',
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        success: function (data) {
        alert("Hi Json");
        alert(data.Leadno);  // **Says data.leadno is undefined**

        response($.map(data.d, function (item) {  // **here I am going some where wrong**
         //**cannot catch response. Help!**

        }))

        },
        failure: function (response) {
            alert(response.d);
        }
    });
});

Please help me on this.. Thanks in Advance!

Answer 1

I see that your JSON is an array with an object. Try data[0].Leadno

Answer 2

$.ajax({
    type: "POST",
    url: "CallDataThroughJquery.aspx/GetLeadDetails",
    data: '{}',
    contentType: "application/json; charset=utf-8",
    dataType: "json",
    success: function (data) {
    alert("Hi Json");
    alert(data.d[0]['Leadno']);  // **Says data.leadno is undefined**

    response($.map(data.d, function (item) {  // **here I am going some where wrong**
     //**cannot catch response. Help!**

    }))

    },
    failure: function (response) {
        alert(response.d);
    }
});

Try your alert with 'data.d[0]['Leadno']'.
