有人能告诉如何修改示例中的xml-grid.js文件

首先;要请求XML文件，它需要与你的javascript文件在同一个web服务器上(否则浏览器将无法加载XML文件)。

加载XML文件到javascript你需要使用XMLHttpRequest对象，虽然如果你想在IE5和IE6中支持你需要做一些ActiveX控制魔术。下面是如何使用XMLHttpRequest的示例:

var request = new XMLHttpRequest();
  // create the request object
request.open('GET', '/xml-grid.js', false);
  // open http session to the file
request.send(null);
  // Send the request (with nothing)
if (request.status == 200) {
  // if request was okay
    console.log(request.responseText);
      // write to console the response in text
}
