代碼如下:
//一個快捷鍵對象
function KeyOne(id, keys, dom, isfun, fun,iskeydown) {
this.id = id;
this.keys = keys;
this.dom = dom;
this.isfun = isfun;
this.fun = fun;
this.isKeydown = iskeydown;
}
//快捷鍵管理類
var KeyConlor = {};
KeyConlor.list = new Array();
//添加一個快捷鍵綁定焦點（當快捷鍵被激發時讓焦點落在指定id對象上）
//使用說明key的值如果是“c,50”則表示“ctrl”和鍵碼為50的組合鍵
// "a,50" 則表示“alt”和鍵碼為50的組合鍵
// "s,50" 則表示“shift”和鍵碼為50的組合鍵
// "50" 則表示鍵碼為50的單鍵（建議使用組合鍵alt）
//id指的是快捷鍵對應的焦點對象。
//dom指的是id對象所在的document對象
KeyConlor.addkeyfouse = function(id, key, dom, iskyedown) {
var keyone = new KeyOne(id, key, dom, false, null, iskyedown);
if (KeyConlor.KeyIsOK(keyone)) {
KeyConlor.list.push(keyone);
} else {
alert("快捷鍵"+keyone.keys+"已經被注冊 不能重復注冊了");
return false;
}
};

} else {

return false;
}
};
//--刪除一個快捷鍵
//KeyConlor.removeFouseKey = function(id) {

//--判斷快捷鍵是不是重復注冊
