firefox如何调用document.onclick获取event参数

请在body里加一句

onLoad="document.onclick = function XXX(event)"

 因为准备用document.onclick = function XXX(event)
报错说找不到event,写到body里,省点事好了.

最新的试过了可以用

document.onclick =abcd;
function abcd(event) {
        event = (event == null)?window.event:event;
}

document.onkeydown = function(event){
    event = event? event:window.event;
    if(event.keyCode == 27){
        window.close();
    }
}


event = (event == null)?window.event:event;
srcelement= event.target?event.target:event.srcElement;

 顺便写一下firefox和ie获取srcElement
