Usage example:

$(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
  }
});

For specific form elements:

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

Before this, you need to remove the onKeyDown event bound to the form submit button before it can be used normally, otherwise the js code will be executed and submitted. Form:

Change

<input type=submit>

to

<input type=button onclick="javascript:if(confirm(&#39;ok&#39;)){this.form.submit();}">
