输入时屏蔽特殊字符

<script language="javascript" type="text/javascript">


var arr=new Array();
arr[0]=/[\`\~\!\@\#\$\%\^\&\*\(\)\+\\\]\[\}\{\'\;\:\"\/\.\,\>\<\]\s\|\=\-\?]/g;
arr[1]=/[^\d]/g;


//屏蔽输入的特殊字符

function filtecharacter(obj, index) {
	obj.value = obj.value.replace(arr[index], "");
}


</script>
<input type="text" name="name" maxlength="19" class="text"   onkeyup="filtecharacter(this,0)" />
