就是enter键处发windows事件，enter键的ASCII是13。
试着理解下面的一段代码：
- <script language=javascript>
- ie = (document.all)? true:false
- if (ie){
- function ctlent(eventobject){if(event.ctrlKey && window.event.keyCode==13){this.document.form1.submit();}}
- }
- </script>
- <form action="http://www.jluvip.com/index.html" method=POST name=form1>
- <textarea cols=95 name=Content rows=12 wrap=virtual onkeydown=ctlent()>
- Ctrl+Enter提交内容信息
- </textarea>
- <input type=Submit value="Submit" name=Submit>
- </form>
这段代码的目的就是实现通过Ctrl和Enter键的组合也可以发送form信息。
看到网上有些代码有使用Keycode==10，如 if(event.ctrlKey && (event.keyCode==13 || event.keyCode==10)){……}
但一直搜索不到KEYcode为10是什么键，可能使用的也不会很多。
关于如何得到一个键在Javascript中的Keycode值，可以参考：
<body onkeypress=alert(event.keyCode)>请按任意键，你将得到该键的键值！
