JQuery键盘处理

一、首先需要知道的是：

1、keydown()

keydown事件会在键盘按下时触发.

2、keyup()

keyup事件会在按键释放时触发,也就是你按下键盘起来后的事件

3、keypress()

keypress事件会在敲击按键时触发,我们可以理解为按下并抬起同一个按键

二、获得键盘上对应的ascII码：

      $(document).keydown(function(event){
              alert(event.keyCode);
      });

$tips: 上面例子中,event.keyCode就可以帮助我们获取到我们按下了键盘上的什么按键,他返回的是ascII码,比如说上下左右键,分别是38,40,37,39；

三、实例（当按下键盘上的左右方面键时）

$(document).keydown(function(event){

//判断当event.keyCode 为37时（即左方面键），执行函数to_left();

//判断当event.keyCode 为39时（即右方面键），执行函数to_right();

if(event.keyCode == 37){

             to_left();
          }else if (event.keyCode == 39){
             to_right();
          }
      });

小实例：

1、

   <title>无标题页</title>
    <script type="text/javascript" src="jQuery.js"></script>
    <script type="text/javascript">
         $(document).keydown(function(event){
                alert(event.keyCode);
         });

</script>

2、

<html >
<head runat="server">
    <title>无标题页</title>
    <script type="text/javascript">
        function GetImages(){
           if(event.keyCode==40) {
               alert("下键");
        }
         else if(event.keyCode==38) {
               alert("上键");
         }
         else if(event.keyCode==37) {
                alert("左键");
         }
         else if(event.keyCode==39) {
                 alert("右键");
         }
     }
    </script>
</head>
<body onkeydown="GetImages();" >
    <form id="form1" runat="server">
       <div>

        </div>
    </form>
