Create two hidden iframes (add "display: none;" to the css style). Make your second iframe point to something on your own domain. Create a hidden form, set its method to "post" with target = your first iframe, and optionally set enctype to "multipart/form-data" (I'm thinking you want to do POST because you want to send multipart data like pictures?) When ready, make the form submit() the POST. If you can get the other domain to return javascript that will do Cross-Domain Communication With Iframes (http://softwareas.com/cross-domain-communication-with-iframes) then you are in luck, and you can capture the response as well.

当然，如果您想使用您的服务器作为代理，您可以避免所有这些。只需将表单提交到您自己的服务器，该服务器将把请求代理到另一个服务器(假设另一个服务器没有设置为注意到IP差异)，获得响应，并返回您想要的任何内容。

如果你想在ASP.net MVC环境下使用JQuery AJAX实现这个功能，请遵循以下步骤: (这是本线程提供的解决方案的总结)

假设"caller.com"(可以是任何网站)需要发布到"server.com"(一个ASP.net MVC应用程序)

On the "server.com" app's Web.config add the following section: <httpProtocol> <customHeaders> <add name="Access-Control-Allow-Origin" value="*" /> <add name="Access-Control-Allow-Headers" value="Content-Type" /> <add name="Access-Control-Allow-Methods" value="POST, GET, OPTIONS" /> </customHeaders> </httpProtocol> On the "server.com", we'll have the following action on the controller(called "Home") to which we will be posting: [HttpPost] public JsonResult Save() { //Handle the post data... return Json( new { IsSuccess = true }); } Then from the "caller.com", post data from a form(with the html id "formId") to "server.com" as follow: $.ajax({ type: "POST", url: "http://www.server.com/home/save", dataType: 'json', crossDomain: true, data: $(formId).serialize(), success: function (jsonResult) { //do what ever with the reply }, error: function (jqXHR, textStatus) { //handle error } });

还有一件重要的事情要注意!! 在上面的例子中描述了如何使用

$.ajax({
    type     : 'POST',
    dataType : 'json', 
    url      : 'another-remote-server',
    ...
});

JQuery 1.6及以下版本在跨域XHR方面有一个bug。 根据Firebug，除了OPTIONS之外，没有其他请求发送。没有职位。在所有。

花了5个小时测试/调优我的代码。在远程服务器(脚本)上添加大量的头文件。没有任何效果。 但后来，我将JQuery lib更新到1.6.4，一切都很顺利。

检查http://taiyolab.com/mbtweet/scripts/twitterapi_call.js中的post_method函数——这是上面描述的iframe方法的一个很好的例子。

保持简单:

跨域: 使用crossDomain: true， 不应该刷新页面: 不，它不会刷新页面，因为当服务器发送回响应时将调用成功或错误异步回调。

示例脚本:

$.ajax({
        type: "POST",
        url: "http://www.yoururl.com/",
        crossDomain: true,
        data: 'param1=value1&param2=value2',
        success: function (data) {
            // do something with server response data
        },
        error: function (err) {
            // handle your error logic here
        }
    });
