saucer(思归) ：问题是如果 src="http://abc.com/aaa.js" 而 abc.com 机器繁忙或有问题，那只能等待超时了,这个时间可能会很久.

my code checks for generic scripting error too, if you just want to check if a js file is loaded, try this

<script language="javascript">
var bLoaded = false;
function window.onload()
{
if (bLoaded)
alert("loaded");
else
alert("not loaded");
}
</script>
<script language="javascript" src="wwww.js" onload="bLoaded=true;"></script>

or you can always call some function which is supposed to be in the included js file in window.onload event handler, for example:

<script language="javascript">
function window.onload()
{
try
{
func();
alert("loaded");
}
catch (e)
{
alert("not loaded");
}
}
</script>

思归那个的确没看出来什么效果。

还有顶楼那个，最好不要用xmlhttp吧，万一我没有这个组件呢？

SO EASY在script src=""那个ASP文件里写这么一个东西

function testlink(){}

然后
<script src="***.asp"></script>
<script>
try
{
var tmp = new testlink();
}
catch(e)
{
alert("错误");
}
</script>

saucer(思归) 的方法有用吗？
我做了一个实验：那个<script>的src是我乱写的。<a>的href也是我乱写的。我用ie5看了，好象没有任何作用呀？？！！！！

<html>
<head>
<SCRIPT>
function fnErrorTrap(sMsg,sUrl,sLine){
var s= "An error was thrown and caught.\n";
s += "Error: " + sMsg + "\n";
s += "Line: " + sLine + "\n";
s += "URL: " + sUrl + "\n";
alert(s);
return true;
}
window.onerror=fnErrorTrap;
</SCRIPT>
</head>
<body>
<script src='http://www.chasrmusic.com/cousdfsfdsfefefsnts/scounter.asp?user=Nizvoo'></script>
<a href='sdfsefsfsefes.html'>sssssssssssss</a>
</body>
</html>
