XDomain 是 JavaScript CORS 跨域请求的一个替代产品,无需任何服务器端的配置。只需要在同域下放置一个 proxy.html 文件即可。该库利用 XHook 来获取所有 XHR,可以无缝的和其他库协同工作。

示例代码:
//do some vanilla XHR var xhr = new XMLHttpRequest(); xhr.open('GET', 'http://xyz.example.com/secret/file.txt'); xhr.onreadystatechange = function(e) { if(xhr.readyState === 4) alert(xhr.responseText); }; xhr.send(); //or if we are using jQuery... $.get('http://xyz.example.com/secret/file.txt').done(function(data) { console.log("got result: ", data); });
