Javascript的错误处理
<script language="javascript">
window.onerror = function(){
alert("出错了！");
}
</script>
</head>
<body onload="sdf()">
</body>
当页面中有js错误时就会触发onerror事件！
try
{
alert("this is an example!");
alert(sdf)
}
catch(exception)
{
var sError = "";
for(var i in exception)
{
sError += i + ":"+exception[i]+"\n";
}
alert(sError);
}
</script>
这段代码利用try catch来处理js错误！
