用javascript限制文本框中的字符输入,屏蔽一些特殊字符

<script language="javascript" src="Comm.js"></script>
<script language="javascript">
	function CheckUser()
	{
		if(!checkLength("UserName" , "用户名称" , 3 , 16 , "~!@#$%^&*+=\\\'\"\<\>"))
			return false;
		window.showModalDialog("Person_CheckUser.asp?UserName=" + RegForm.UserName.value ,"Person_CheckUser","");
	}
</script>
<table width="966" border="0" align="center" cellpadding="0" cellspacing="0">

	<tr>
		<td height="350" valign="top" bgcolor="#F9F9F9"><form id="RegForm" name="RegForm" method="post" style="margin:0" onSubmit="return CheckForm();">
			<table width="700" border="0" align="center" cellpadding="0" cellspacing="0">
