使用

<script language="javascript">

     function keyevent(){

     if(event.keyCode==13)

     alert("#$%#%#^^%");

     }

     document.onkeydown = keyevent;

< /script>

event.keyCode值為37﹐38﹐39﹐40對應按下的方向鍵分別是 左﹐上﹐右﹐下

"javascript:if (event.keyCode < 45 || event.keyCode > 57) event.returnValue = false;");

if(event.keycode==13)就代表按下的是回车键盘

"javascript:if (event.keyCode > 45 && event.keyCode < 57) event.returnValue = false;");

使用javascript在WEB页面中截获键盘输入

使用event对象的keyCode属性判断输入的键值

eg：if(event.keyCode==13)alert(“enter!”);

键值对应表
