问题:未调用 Ajax 回调方法 (get)。

$("input[id*='chkSelect']:checked").each(function (i, v) {

    $.get("AjaxCallHandler.aspx?tc_id=" + tc_id, function (response) {                    
        if (response != null && response != '') {
                //update some labels with the return type
            }
        }
    });
});

服务器端:

protected void Page_Load(object sender, EventArgs e)
{
    var str = Request.QueryString["tc_id"] != null ? Request.QueryString["tc_id"] as string : string.Empty;
    int tc_id;
    if (int.TryParse(str, out tc_id))
    {   
        string response = string.Empty;

        if (tc_id %2 == 0)
        {
            response = "sessionId1,Success";
        }
        else
        {
            response = "sessionId2,Failure";
        }

        Response.Clear();            //clears the existing HTML
        Response.ContentType = "text/plain";  //change content type
        Response.Write(response);
        Response.End();             //end
    }
}

PS在我将不同的母版页应用于页面之前,代码工作得非常好。我尝试了不同的 get 方法重载来检查错误,但这也无济于事。

function (response, textStatus, jqXHR) {                    
        if (response != null && response != '') {
                //update some labels with the return type
            }
        }
    }

正如凯文所建议的那样,我尝试在$.get中添加 failHandler

$.get("AjaxCallHandler.aspx?tc_id=" + tc_id, 
    function (response, textStatus, jqXHR) {                    
        if (response != null && response != '') {
                //update some labels with the return type
            }
        }
    }).fail(failHandler);

    function failHandler(data, textStatus, jqXHR) {
        console.log(data);
        console.log(textStatus);
        console.log(jqXHR);
    };

这是输出 文本状态: parsererror jqXHR: SyntaxError

我从服务器返回的只是"sessionId1,Success"不知道出了什么问题?
