m.js文件：
var mcontainm=document.getElementById("menu-parent").getElementsByTagName("a");
var mcontains=document.getElementById("sub_box").getElementsByTagName("div");
for(var mi=0;mi mcontainm[mi].onmouseover=function(){mover(this.id.replace("par",""));}
mcontains[mi].onmouseover=function(){mover(this.id.replace("son",""));}
mcontainm[mi].onmouseout=function(){mout(this.id.replace("par",""));}
mcontains[mi].onmouseout=function(){mout(this.id.replace("son",""));}
}
if(def!=null){document.getElementById("par"+def).className="menuA";document.getElementById("son"+def).style.display="block";}


public.js文件很长 就不发了 但应该与它无关。
