为什么ajax调用会失败？

我正在 http://www.mywebsite.com 上做跨域Ajax （使用jQuery）调用（http://myownajax.projects.it/folder/mypage.aspx）。

$.ajax({
    url: 'http://myownajax.projects.it/folder/mypage.aspx ',
    success: function(data) {
        console.log(data);
    }
});

可以轻松输出“ Hello”：

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="mypage.aspx.cs" Inherits="folder_mypage" %>

Hello

但老是收到200 OK错误。为什么？ 该如何解决？

You must specify the dataType:"jsonp", and cross domain ajax only support type:"GET". type:"POST" is not allowed.

Cross site scripting (aka XSS) is blocked by browsers as it is a security risk.

If you must retrieve data from another URL, you must use the JSONP format and GET requests only.

Try this:

$.ajax({
    url: 'http://myownajax.projects.it/folder/mypage.aspx',
    type: 'get', // this is optional as 'get' is the default.
    datatype: 'jsonp',
    success: function(data) {
        console.log(data);
    }
});
