当我通过ajax使用跨域调用泛型处理程序时，ajax成功时数据未定义

Question

When I call generic handler using cross domain by ajax then data is undefined on success of ajax.

    function loadUser() {
        currentUser = null;

            $.ajax({
                type: 'GET',
                url: 'http://ips.rhinodev1.edge360.dev/EventVelocity/AsyncHandlers/GetCurrentUser.ashx?',
                dataType: 'script',
                crossDomain: true,
                encode: true
            }).done(loadUser_Done).fail(loadUser_Fail);
        }

function loadUser_Done(data, txtStatus, jqXHR) {
    if (txtStatus == "success") {
        try { TestWildCard(); } catch (e) { currentUser_UseWildCardDNS = false;    }
        loadDevices();
    }
    else {
        // Redirect To Login
        window.location.href = "Login.aspx";
    }
}

When calling loadUser() function its call generic handler, and go to loadUser_Done() function, in that I have got 'txtStatus' - "success" , but 'data' is undefined.

So, basically I didn't get my response, so how to solve this issue? Please give answer.

basically you can just declare success property in the ajax syntax:

function loadUser() {
        currentUser = null;

            $.ajax({
                type: 'GET',
                url: 'http://ips.rhinodev1.edge360.dev/EventVelocity/AsyncHandlers/GetCurrentUser.ashx?',
                dataType: 'script',
                crossDomain: true,
                encode: true,
                success: loadUser_Done(data, txtStatus, jqXHR)
                error: function(error){
                    console.log(error);
                }
            })
        }

function loadUser_Done(data, txtStatus, jqXHR) {
    if (txtStatus == "success") {
        try { TestWildCard(); } catch (e) { currentUser_UseWildCardDNS = false;    }
        loadDevices();
    }
    else {
        // Redirect To Login
        window.location.href = "Login.aspx";
    }
}
