function ContextMenu(id)
{
this.id = id;
ContextMenu.doc = document;
this.Objects = new Array();

ContextMenu.current = ContextMenu.doc.createElement("div");
ContextMenu.current.id = this.id;
ContextMenu.current.className ="MenuDiv";
ContextMenu.current.style.display = "none";
ContextMenu.current.style.position = "absolute";
this.table = ContextMenu.doc.createElement("table");
this.table.cellpadding = "0";
this.table.cellspacing = "0";
this.table.className="MenuTable";
ContextMenu.current.appendChild(this.table);
ContextMenu.doc.body.appendChild(ContextMenu.current);

ContextMenu.doc.attachEvent("onmousedown",
function(ev){
if(ev.button == 2){
ContextMenu.show(event.clientX,event.clientY);
}
}
);
ContextMenu.doc.oncontextmenu = function() { return false;}

this.table.onmouseover = function()
{
//在這裡怎麼樣調用ContextMenu的show方法呢，謝謝？
}
}

ContextMenu.prototype.show()
{

}
