JavaScript 接收键盘指令示例_javascript技巧

请按下键盘上的A键，会跳转到脚本之家的首页

<script language="JavaScript"> <!-- var hotkey=97 var destination="http://www.jb51.net" if (document.layers) document.captureEvents(Event.KEYPRESS) function backhome(e){ if (document.layers){ if (e.which==hotkey) window.location=destination } else if (document.all){ if (event.keyCode==hotkey) window.location=destination } } document.onkeypress=backhome onkeydown="javascript:onenter();" function onenter(){ if(event.keyCode==13){ alert("回车"); } } --> </script>
[Ctrl+A 全选 注:如需引入外部Js需刷新才能执行]
