请问在onclick(event,display)中display的值究竟是如何被传递进去的？

代码如下：
btnBu.addEventListener(LMouseEvent.MOUSE_UP,onclick);
function onclick(event,display){
var selfValue,enemyValue;
if(display.name == "shitou"){
selfValue = 0;
}else if(display.name == "jiandao"){
selfValue = 1;
}else if(display.name == "bu"){
selfValue = 2;
}
enemyValue = Math.floor(Math.random() * 3);
selfBitmap.bitmapData = showList[selfValue];
enemyBitmap.bitmapData = showList[enemyValue];
var result = checkList[selfValue][enemyValue];
if(result == -1){
loss += 1;
}else if(result == 1){
win += 1;
}else{
draw += 1;
}
console.log(win + loss + draw);
selfTextWin.text = "胜利次数：" + win;
selfTextLoss.text = "失败次数：" + loss;
selfTextDraw.text = "平局次数：" + draw;
selfTextAll.text = "猜拳次数：" + (win + loss + draw);
}

这个display是当前空间自身，相当于thisonclick可以动态传参Html代码 复制代码代码如下:<body> <input id="certid" type="text" value="123456" > <input id="btn" type="button" value="button" onclick=""> </body>Javascript代码 复制代码代码如下:<script> function show(value1,value2) { alert(value1+","+value2); }var i = 10; btn.onclick = function(){ show(certid.value,i); }; <script>这样就实现了动态给onclick事件句柄赋值,并支持参数的传递.
