javascript实现树形菜单的方法_javascript技巧

本文实例讲述了javascript实现树形菜单的方法。分享给大家供大家参考。具体如下：

var ME={
  ini:{i:true,d:{},d1:{},h:0,h1:0,h2:0},
  html:function(da,f){
    var s='

'; for(var i=0,l=da.length;i'+da[i].ming+''; this.ini.i=false; s+=this.html(da[i].pid,(i+1==l)); }else{ s+='
• '+da[i].ming+''; } s+='
'; } s+='

'; return s; }, st:function(id,da){ document.getElementById(id).innerHTML=this.html(da); }, yc:function(a){ var s=a.className.substr(1); if(s%2){ this.ini.d=a.parentNode.children[2]; this.ini.h1=this.hei(this.ini.d); this.ini.h3=this.ini.h1/10; this.yc1(1); a.className='s'+(parseInt(s)+1); a.parentNode.children[1].children[0].className='r2'; var ol=a.parentNode.parentNode._; if(typeof(ol)=='object'){ this.ini.d1=ol; this.ini.h=ol.offsetHeight; this.ini.h2=this.ini.h/10; this.yc2(1); ol.parentNode.children[0].className='s'+(parseInt(ol.parentNode.children[0].className.substr(1))-1); ol.parentNode.children[1].children[0].className='r1'; } a.parentNode.parentNode._=a.parentNode.children[2]; }else{ this.ini.d1=a.parentNode.children[2]; this.ini.h=this.ini.d1.offsetHeight; this.ini.h2=this.ini.h/10; this.yc2(1); a.className='s'+(parseInt(s)-1); a.parentNode.children[1].children[0].className='r1'; a.parentNode.parentNode._=''; } }, yc1:function(b){ var h1=ME.ini.h1-(11/(b+1)-1)*ME.ini.h3; with(ME.ini.d.style){ height=h1+'px'; display='block'; } if(b
