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(&#39;ok&#39;)){this.form.submit();}">

即可。
