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。

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。

如果您可以访问所有相关的服务器，请在另一个域请求的页面的回复标题中放入以下内容:

PHP:

header('Access-Control-Allow-Origin: *');

例如，在Drupal的xmlrpc.php代码中，你会这样做:

function xmlrpc_server_output($xml) {
    $xml = '<?xml version="1.0"?>'."\n". $xml;
    header('Connection: close');
    header('Content-Length: '. strlen($xml));
    header('Access-Control-Allow-Origin: *');
    header('Content-Type: application/x-www-form-urlencoded');
    header('Date: '. date('r'));
    // $xml = str_replace("\n", " ", $xml); 

    echo $xml;
    exit;
}

这可能会产生安全问题，您应该确保采取了适当的措施来验证请求。

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
        }
    });

创建一个iFrame， 在里面放入一个隐藏输入的表单， 将表单的动作设置为URL， 向文档中添加iframe 提交表格

伪代码

 var ifr = document.createElement('iframe');
 var frm = document.createElement('form');
 frm.setAttribute("action", "yoururl");
 frm.setAttribute("method", "post");

 // create hidden inputs, add them
 // not shown, but similar (create, setAttribute, appendChild)

 ifr.appendChild(frm);
 document.body.appendChild(ifr);
 frm.submit();

你可能想样式iframe，隐藏和绝对定位。不确定跨站点发布将被浏览器允许，但如果是这样，这是如何做到的。
