使用示例：

$(window).keydown(function(event){ switch(event.keyCode) { // ... // 不同的按键可以做不同的事情 // 不同的浏览器的keycode不同 // 更多详细信息: http://unixpapa.com/js/key.html }});

针对特定表单元素：

$('#Post_tags').keydown(function(event){ switch(event.keyCode){case 13: alert(this.value); break; }});

在此之前，需要将绑定在表单submit按钮上的onKeyDown事件去除才可以正常使用，否则会执行该js代码后提交表单：

将

<input type=submit>

改为

<input type=button onclick='javascript:if(confirm(’ok’)){this.form.submit();}'>

即可。
