模拟JS的CONFIRM问题
代码是这样的，
//oo
function oo(obj){
return typeof(obj)== "string "?document.getElementById(obj):obj;
}
function ofocu(obj){
window.tmpObj=oo(obj);
window.setTimeout( "window.tmpObj.focus() ",100);
}

function ShowConfirm(caption){
var l,w,h,x,y,i,n,bg,o;
w=284;
h=194;
x=(document.body.clientWidth-w)/2;
y=(document.body.clientHeight-h)/2+document.body.scrollTop;
o=document.createElement( "div ");
o.style.cssText= "display:none;z-index:99;position:absolute;left:0;top:0;width:100%;height: "+document.body.scrollHeight+ ";background:url(blank.gif) ";
o.id= "conMsg ";
document.body.appendChild(o);
l= " <div style=cursor:default;position:absolute;left: "+x+ ";top: "+y+ ";width: "+w+ ";height: "+h+ "> ";

}

function Del(){
ShowConfirm();
//请问在这里怎么判断ShowConfirm()之后，用户点的是什么，才能往下执行？？？如果用户点击取消，只隐藏divConfrim就行了，如果是确定那么就往下执行。
alert( "往下执行的代码！ ");//这里是一定要等用户点确定后才能执行的代码
}


到底应该怎么做呢？？？？？？？？？？？？？？？？？？？？？？？？？？？？
