以下是几种常用的方法，当然取数据的后缀名可以为.asp,.jsp等等的带参数url.
1.
<script language="javascript">
function loadxml(url){
var loxml = new activexobject("msxml.domdocument");
loxml.async = false;
loxml.load(url);
return loxml.xml;
}
</script>
<input type="button" value="loadxml方法" onclick="alert(loadxml('data.txt'))">
-- data.xml --- //数据是xml格式
<xml/>
2.
<input type="button" value="loadjs方法" onclick="loadjs('data.js')">
<script id="getnewtext"></script>
<script language="javascript">
function loadjs(url){
getnewtext.src = url;
}
function setdata(s){
alert(s)
}
</script>
-- data.js --- //数据是js脚本赋的变量或直接执行得到结果
setdata("abc");
3.
<input type="button" value="loadframe方法" onclick="loadframe('data.html')">
<script language="javascript">
function loadframe(url){
document.all.getdata.src = url;
}
function setdata(s){
alert(s)
}
</script>
<iframe id="getdata" style='display:none;'></iframe>
-- data.html --
<script>
parent.setdata("abc")
</script>
