无聊中还看到学校的论坛有人问怎么下载校园网的电影，以前有个小宏下载是用图片地址弄出电影地址的，但是没有图片的电影呢，下不了了，今天刚好研究ajax技术，拿就用它吧。代码如下：

<script language=”JavaScript”>
function requestUrl(pageText){
var moviestart = 0;
var result=””;
var XMLHTTP = new ActiveXObject(“Microsoft.XMLHTTP”);
moviestart = pageText.indexOf(“,’MOVIE-“,moviestart)+2;
while (moviestart>2){
serverIDstart = pageText.indexOf(“Player(“,moviestart – 30);
serverIDover = pageText.indexOf(“,”,serverIDstart);
serverID = pageText.substring(serverIDstart + 7, serverIDover);
movieover = pageText.indexOf(“‘)”,moviestart);
movietext = pageText.substring(moviestart, movieover);
movieIDover = pageText.indexOf(“,”,serverIDover + 1)
movieID = pageText.substring(serverIDover + 1, movieIDover);
adressMovie = “http://bbs.smu.edu.cn/Campus/movie/show.aspx?” + “ServerID=” + serverID + “&MovieID=” + movieID + “&FileName=” + movietext;
XMLHTTP .open(“get”,adressMovie,false);
XMLHTTP .send();
result+=”<p><a href=\””+XMLHTTP .responseText+”\”>”+XMLHTTP .responseText+”</a></p>”;
moviestart+=240
moviestart = pageText.indexOf(“,’MOVIE-“,moviestart)+2;
}
document.getElementById(“result”).innerHTML=result;
}
function get(url)
{
if (url.search(“http://bbs.smu.edu.cn/”)==0){
var XMLHTTP = new ActiveXObject(“Microsoft.XMLHTTP”);
XMLHTTP .open(“get”,url,false);
XMLHTTP .send();
requestUrl(XMLHTTP .responseText);
}
else{
alert(“输入的网址错误！”);
return false;
}
}
