在asp.net中调用Ajax

Question

I am making JQuery Ajax call in asp.net, I am returning String with my WebMethod, But on success of ajax call I am getting complete HTML of page in result.I also used type: "get" but no luck, below is my code for ajax call

$.ajax({
    type: "POST",
    url: "MyPage.aspx/GetData", //url to point your webmethod          
    success: function (Result) {
        if (Result != "")
            alert( Result);
        },
    error: function () { alert('error'); }
});

---

[System.Web.Services.WebMethod()]
public string GetData()
{
    //getting value from Database and returning
}

I am calling this Ajax in MyPage.aspx

Try it like this. With the contentType: "application/json; charset=utf-8"

$.ajax({
    type: "POST",
    url: "MyPage.aspx/GetData", //url to point your webmethod          
    contentType: "application/json; charset=utf-8",
    success: function (Result) {
        if (Result != "")
            alert( Result);
        },
    error: function () { alert('error'); }
});
