javascript - jQuery Ajax Post导致500内部服务器错误(JQuery Ajax Post results in 500 Internal Server Error)

Question

I am trying to perform this AJAX post but for some reason I am getting a server 500 error.

(我正在尝试执行此AJAX帖子，但是由于某些原因，我遇到了服务器500错误。)

I can see it hit break points in the controller.

(我可以看到它在控制器中达到了断点。)

So the problem seems to be on the callback.

(因此问题似乎出在回调上。)

Anyone?

(任何人？)

$.ajax({
    type: "POST",
    url: "InlineNotes/Note.ashx?id=" + noteid,
    data: "{}",
    dataType: "json",

    success: function(data) {
        alert(data[1]);
    },
    error: function(data){
        alert("fail");
    }
});

This is the string that should be returned:

(这是应该返回的字符串：)

{status:'200', text: 'Something'}

Answer 1

I suspect that the server method is throwing an exception after it passes your breakpoint.

(我怀疑服务器方法在通过断点后会引发异常。)

Use Firefox/Firebug or the IE8 developer tools to look at the actual response you are getting from the server.

(使用Firefox / Firebug或IE8开发人员工具查看您从服务器获得的实际响应。)

If there has been an exception you'll get the YSOD html, which should help you figure out where to look.

(如果有异常，您将获得YSOD html，这应该可以帮助您确定要查找的位置。)

One more thing -- your data property should be {} not "{}", the former is an empty object while the latter is a string that is invalid as a query parameter.

(还有一件事-您的数据属性应为{}而不是“ {}”，前者是一个空对象，而后者是一个无效的字符串，不能作为查询参数。)

Better yet, just leave it out if you aren't passing any data.

(更好的是，如果不传递任何数据，则将其删除。)
