这篇文章主要介绍了Atitit.js的键盘按键事件捆绑and事件调度的相关资料,需要的朋友可以参考下

1. Best的方法还是

objEvtMap[ id+evt ]=function(evt,element)

2. Event bind

function bindEvent_4_dataBlock()

{

var arr=$("#table1 li");

arr.each(function(index, element) {

$(element).keypress(function(){

alert('keypress');

});

var id="data_aid_"+index;

$(element).attr("id","data_aid_"+index);

objEvtMap[ id ]=function(evt,element)

{

if(evt=="down")

key_press_hadler($(element));

if(evt=="up")

key_press_hadler4up($(element));

if(evt=="left")

{};

if(evt=="rit")

{}

};

});

}

3. Event dispatch

document.onkeydown=function(event){

var e = event || window.event || arguments.callee.caller.arguments[0];

alert("keycode:"+e.keyCode);

if(e && e.keyCode==40 ){//下

//alert('40=下键，39=右键');

var now=$(".selected");

var id=$(now).attr("id");

var func=objEvtMap[id ];

func("down",now);

//key_press_hadler(now);

return false;

}

js中获取键盘事件

<script type="text/javascript" language=JavaScript charset="UTF-">

document.onkeydown=function(event){

var e = event || window.event || arguments.callee.caller.arguments[];

if(e && e.keyCode==){ // 按 Esc 

//要做的事情

}

if(e && e.keyCode==){ // 按 F 

//要做的事情

} 

if(e && e.keyCode==){ // enter 键

//要做的事情

}

}; 

</script>

只要你定义了这些键的动作，你在浏览器里按下这些键就会响应，兼容目前所有浏览器。

使用event对象的keyCode属性判断输入的键值

eg：if(event.keyCode==)alert(“enter!”);

键值对应表

A　　X 　U 　　X

B　　X　 V　　 X

C　　X　 W　　 X

D　　X　 X 　　X

E　　X　 Y　　 X

F　　X　 Z　　 X

G　　X　 　　 X

H　　X　 　　 X

I　　X　 　　 X

J　　X　 　　X

K　　X　 　　X

L　　X　 　　X

M　　X　 　　 X

N　　X 　 　　X

O　　X 　 　　X

P　　X 　 　　X

Q　　X　ESC　　XB

R　　X　CTRL 　X

S　　X　SHIFT　X

T　　X　ENTER　XD

如果要使用组合键，则可以判断是否同时按下了这几个键，比如ctrl键、shift键以及alt键的组合使用就可以判断是否多按下了ctrl键、shift键以及alt键
