javascript仿qq介面的折疊選單實現程式碼_導航選單

最近一直在研究網頁特效,看到qq界面的折疊菜單,於是冒出個想法,自己寫一個類似的,上網查了一下,發現已經有不少類似的菜單效果,不管那麼多,先寫著再說吧.

以下是html結構:

sdfds

dsfdsfsdfsd

dsf

dsfdsfsdf

.................. .....

id為a裡的便是你要加入的選單的標題與內容.

下面是javascript程式碼:

複製程式碼 程式碼如下:

sx.activex.packmenu={
create:function(t) {
var a=document.createElement("div");
var _t=t;
a.style.height="300px";
a.style.width="150px";
a.style.border="1px red solid";
a.style.overflow="hidden";
for(var i=0;i var h=document.createElement("div");
var b=document.createElement("div");;
h.style.backgroundColor="blue";
h.style.height= "10%";
b.style.padding="5px";
b.style.textAlign="center";
b.style.border="1px green solid";
h .innerHTML=t[i][0];
b.innerHTML=t[i][1];
b.style.overflow="hidden";
b.style.height="0px ";
b.style.display="none";
h.onclick=function(){
if(this.nextSibling.style.display=="none"){
this. nextSibling.style.height="1px";
this.nextSibling.style.display="block";
this.h=window.setInterval(function(t,t1){
return function() {
if(!t1) return;
//alert(t.nextSibling.offsetHeight);
if(parseInt(t.nextSibling.style.height)t.nextSibling.style.height=parseInt(t.nextSibling.style.height) 3 "%";
t1.style.height=parseInt (t1.style.height)-3 "%";
}
else{
t.nextSibling.style.height=100-_t.length*parseInt(a.all[0].style. height) "%";;
t1.style.display="none";
t1.style.height="0px";
window.clearInterval(t.h);
}
}
}(this,(function(){
for(var ii=0;iiif(parseInt(a.all[ii].style. height)>10)
return a.all[ii];
}
})()),10);
}
else{
if(this!=this .parentNode.firstChild){
this.previousSibling.style.height="1px";
this.previousSibling.style.display="block";
}
else{
this. parentNode.lastChild.style.display="block";
this.parentNode.lastChild.style.height="1px";
}
this.h=window.setInterval(function(t,t1) {
return function(){
if(!t1) return;
if(parseInt(t.nextSibling.style.height)>3){
if(t!=t.parentNode. firstChild)
t.previousSibling.style.height=parseInt(t.previousSibling.style.height) 3 "%";
else
t.parentNode.lastChild.style.height=parseInt(t.parentNodeInt(t. .lastChild.style.height) 3 "%";
t1.style.height=parseInt(t1.style.height)-3 "%";


}
else{
if(t!=t.parentNode.firstChild)
t.previousSibling.style.height=100-_t.length*parseInt(a.all[0].style.height) "%";
else
t.parentNode.lastChild.style.height=100-_t.length*parseInt(a.all[0].style.height) "%";
t.nextSibling.style.display=" none";
t.nextSibling.style.height="0px";
window.clearInterval(t.h);
}
}
}(this,(function(){
for(var ii=0;iiif(parseInt(a.all[ii].style.height)>10)
return a.all[ii] ;
}
})()),1);
}
}
a.appendChild(h);
a.appendChild(b);
a. all[1].style.display="block";
a.all[1].style.height=100-t.length*parseInt(a.all[0].style.height) "%";
}
return a;
}
}

入口參數t是你要傳遞的二維陣列,以一個標題加上內容為一個陣列項目的形式:
下面是呼叫程式碼:






<script> <BR>var a=sx.activex.packmenu.create([["asd","sadsadas"],["sd"," sadsaas"],["w","waedqwdq"],["e","efwefw"]]); <BR>//a.contentEditable=true; <BR>document.body.appendChild(a); <BR></script>


搞定,有興趣的朋友可以看下效果.
