AJAX中的成功或错误回叫不起作用

Question

$(document).ready(function () {
$("#loginForm").submit(function (e)
{
    var Data = $(this).serializeArray();
    var formURL = $(this).attr("action");
    var PostData =
    {
        "CompanyName": $(this).serializeArray().CompanyName,
        "Username": $(this).serializeArray().Username,
        "Password": $(this).serializeArray().Password
    }
    $.ajax(
    {
        url: formURL,            
        data: PostData,
        success: function (data, textStatus, jqXHR) {
            alert("Data" + data);
            alert("Jq" + jqXHR);
            alert("textStatus" + textStatus);
        },
        error: function (jqXHR, textStatus, errorThrown) {
            alert("Failed..ajax error response type " + textStatus);
        }
    });
    e.preventDefault(); //STOP default action
})
});

$("#loginForm").submit(); //SUBMIT FORM

This is a simple Ajax request to the C# code,that i have.I know for sure that the C# is giving a correct value(according to the situation).

C# return true or false as per the situation.But in any case this Ajax script neither giving me a alert window which i have coded for.

Instead i get this response from

This XML file does not appear to have any style information associated with it. The document tree is shown below. <boolean xmlns="http://schemas.microsoft.com/2003/10/Serialization/">false</boolean>

When false and just the value in the tag changes when its true. Can anyone tell me why neither success or error is not working.

Answer 1

As you can tell from it's name the .serializeArray() method returns an array -- not an object. The array is of the form:

[
  {
    name: "a",
    value: "1"
  },
  {
    name: "b",
    value: "2"
  },
  {
    name: "c",
    value: "3"
  }
]

• array of objects
• Ref: http://api.jquery.com/serializearray/
• What you need : http://api.jquery.com/serialize/

Therefore to access the third value you would need to supply the index 2 -- ..[2].value ... name ...[2].name . Your code has errors that would prevent the ajax call from being made. Is it possible that error is coming from somewhere else?

Therefore change:

var PostData =
{
    "CompanyName": $(this).serializeArray().CompanyName,
    "Username": $(this).serializeArray().Username,
    "Password": $(this).serializeArray().Password
}

To:

var PostDate = $(this).serialize();

Something that make work better is this:

$("#loginForm").submit(function (event) {
    event.preventDefault();
    $.post($(this).attr("action"), $(this).serialize())
        .done(function (results) {
        alert(results);
    })
        .fail(function (error) {
        alert(error);
    })
        .always(function () {
        alert("AJAX Complete");
    });
});
