/*CNLTreeMenu Start*/
.CNLTreeMenu img.s {cursor:pointer;vertical-align:middle;}
.CNLTreeMenu ul {padding:0;}
.CNLTreeMenu li {list-style:none;padding:0;}
.Closed ul {display:none;}

#CNLTreeMenu1 ul {margin:0 0 0 17px;}
#CNLTreeMenu1 img.s {width:20px;height:15px;}
#CNLTreeMenu1 .Opened img.s {background:url(skin1/opened.gif) no-repeat 0 0;}

#CNLTreeMenu2 ul {margin:0 0 0 17px;}
#CNLTreeMenu2 img.s {width:17px;height:15px;}
#CNLTreeMenu2 .Opened img.s {background:url(skin2/opened.gif) no-repeat 4px 6px;}
#CNLTreeMenu2 .Closed img.s {background:url(skin2/closed.gif) no-repeat 3px 6px;}
#CNLTreeMenu2 .Child img.s {background:url(skin2/child.gif) no-repeat 3px 5px;}
#CNLTreeMenu3 ul {margin:0 0 0 17px;}
#CNLTreeMenu3 img.s {width:34px;height:18px;}
#CNLTreeMenu3 .Opened img.s {background:url(skin3/opened.gif) no-repeat 0 1px;}
#CNLTreeMenu3 .Closed img.s {background:url(skin3/closed.gif) no-repeat 0 1px;}
#CNLTreeMenu3 .Child img.s {background:url(skin3/child.gif) no-repeat 13px 2px;}
/*CNLTreeMenu End*/
/*Temp CSS for View Demo*/
#CNLTreeMenu1,#CNLTreeMenu2,#CNLTreeMenu3 {float:left;width:249px;border:1px solid #99BEEF;background:#D2E4FC;color:inherit;margin:3px;padding:3px;}

.ViewCode {
 clear:both;
 border:1px solid #FFB900;background:#FFFFCC;color:inherit;margin:3px;padding:3px;
}
.ViewCode h6 {color:#00f;}

JavaScript代码:

function Ob(o){
 var o=document.getElementById(o)?document.getElementById(o):o;
 return o;
}
function Hd(o) {
 Ob(o).style.display="none";
}
function Sw(o) {
 Ob(o).style.display="";
}
function ExCls(o,a,b,n){
 var o=Ob(o);
 for(i=0;i";
 this.ImgBlankB ="JavaScript+CSS无限极分类效果完整实现方法_javascript技巧";
 for (i=0;i
