据说这是JS读取远程的文件.但是我没有测试过,贴于此仅供参考
<script type="text/javascript"><!--
//页面级XMLHttp对象
var xmlhttp;
//向服务器发送信息函数
function getPage(pageURL) {
xmlhttp = createXMLHttp();
if (xmlhttp)
{
xmlhttp.onreadystatechange = setPageData;
xmlhttp.open('GET', pageURL);
xmlhttp.send(null);
}else{
alert("XMLHttpRequest对象为空");
}
}
//回调函数，获得从服务器回发的文档信息并显示在disp层中
function setPageData(){
if (xmlhttp.readyState == 4 && xmlhttp.status == 200){
var word = bytes2BSTR(xmlhttp.responseBody);
document.getElementById("disp").innerHTML = word ;
}
}
//创建XMLHttp对象，用于读取远程文档
function createXMLHttp(){
try {
return new ActiveXObject ("Microsoft.XMLHTTP");
}catch(e){
try {
return new XMLHttpRequest();
}catch(e) {
return null;
}
}
return null;
}
