简单的Ajax不工作 [英] Simple AJAX not working

问题描述

我有这样的AJAX code，但它似乎并没有抛出警告的方法。相反，没有任何反应。我看着它的提琴手和得到这个错误信息： {消息：有一个错误处理请求，堆栈跟踪：，ExceptionType：}

I have this AJAX code, but it doesn't seem to throw the 'alert' method. Instead, nothing happens. I looked at it with Fiddler and got this error message: {"Message":"There was an error processing the request.","StackTrace":"","ExceptionType":""}

我想打电话给在code-后面称为Web方法 MyWebMethod ：

I'm trying to call a web method in the code-behind called MyWebMethod:

 $.ajax({   type: "POST",
            url: "Test.aspx/MyWebMethod",
            data: "{" + username + "}",
            contentType: "application/json; charset=utf-8",
            dataType: "json",

            success: function() {
                alert("success");
            },

            fail: function() {
                alert("Fail");
            }
 });

Web方法工作得很好，当我有在页面上的脚本经理，但我想删除脚本经理，认为使用AJAX将是最好的方式。

The web method worked fine when I had a script manager on the page, but I want to remove the script manager and thought that using AJAX would be the best way.

感谢

推荐答案

我认为，如果你改变失败到错误，你会得到第二次警告框。

I think if you change fail to error, you'll get the second alert box.

我想，如果你再改

data: "{" + username + "}"

到

data: "{ 'username': '" + username + "' }"

你会得到第一个警报，但很难​​知道，没有看到该服务你打电话。

you'll get the first alert, although it's hard to know that without seeing the service you're calling.
