过虑特殊字符输入的js代码

<script>
function TextValidate() {
var code;
var character;
var err_msg = "文件夹名不能包含下列字符之一:/n // / : * ? /" < > | & , ";
if (document.all)
{
code = window.event.keyCode;
}
else {
code = arguments.callee.caller.arguments[0].which;
}
var character = String.fromCharCode(code);
var txt = new RegExp("[//*,//&,////,///,//?,//|,//:,//<,//>,/"]");
if (txt.test(character)) {
alert(err_msg);
if (document.all) {
window.event.returnValue = false;
}
else {
arguments.callee.caller.arguments[0].preventDefault();
}
}
}
</script>
