太值得收藏了！！
表单相关收集
只能是写限定的东西
-----------------------------------------------------------------------------------
ENTER键可以让光标移到下一个输入框
<input onkeydown="if(event.keyCode==13)event.keyCode=9" >
只能是中文<input onkeyup="value=value.replace(/[ -~]/g,'')" onkeydown="if(event.keyCode==13)event.keyCode=9">
只能是英文和数字.屏蔽了输入法<input style="ime-mode:disabled" onkeydown="if(event.keyCode==13)event.keyCode=9">
只能输入英文和数字<input onkeyup="value=value.replace(/[\W]/g,'') "onbeforepaste="clipboardData.setData('text',clipboardData.getData('text').replace(/[^\d]/g,''))" onkeydown="if(event.keyCode==13)event.keyCode=9">
只能是数字<input onkeyup="value=value.replace(/[^\d]/g,'') "onbeforepaste="clipboardData.setData('text',clipboardData.getData('text').replace(/[^\d]/g,''))">
只能显示，不能修改的文本框<input readOnly value="只能显示，不能修改">
-----------------------------------------------------------------------------------
只能是数字,判断按键
-----------------------------------------------------------------------------------
<script language=javascript>
function onlyNum()
{
if(!((event.keyCode>=48&&event.keyCode<=57)||(event.keyCode>=96&&event.keyCode<=105)||(event.keyCode==8)))
event.returnValue=false;
}
</script>
<input onkeydown="onlyNum();">
-----------------------------------------------------------------------------------
附：获取键盘的KeyCode
-----------------------------------------------------------------------------------

if(event.keyCode==32){realkey='\' 空格\''}

限制网页用键盘
-----------------------------------------------------------------------------------
<body onkeydown="alert('禁用');return false;">
限制键盘的某个键：body onkeydown="if(event.keyCode==num){alert('禁用');return false;}

再加个找按键的值
