可能有人請告訴如何修改示例中的xml-grid.js文件

Answer 1

首先;請求XML文件需要與您的JavaScript文件位於同一個Web服務器中（否則瀏覽器將無法加載XML文件）。

要將XML文件加載到JavaScript，您需要使用XMLHttpRequest object，但如果您需要在IE5和IE6中支持，則需要執行一些ActiveX控件魔術。這裏是一個如何使用XMLHttpRequest實現的例子：

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 

}
