最近一直在研究网页特效,看到qq界面的折叠菜单,于是冒出个想法,自己写一个类似的,上网查了一下,发现已经有不少类似的菜单效果,不管那么多,先写着再说吧.
以下是html结构:
<div id="a"><div id="h1">sdfds</div><div id="b1">dsfdsfsdfsd</div><div id="h2">dsf</div><div id="b2">dsfdsfsdf</div>.......................</div>
id为a里的便是你要添加的菜单的标题和内容.
下面是javascript代码:
复制代码 代码如下:
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<t.length;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)<100-_t.length*parseInt(a.all[0].style.height)-3){
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;ii<a.all.length;ii++){
if(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.parentNode.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;ii<a.all.length;ii++){
if(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;
}
}
入口参数t是你要传递的二维数组,以一个标题加内容为一个数组项的形式:
下面是调用代码:
<html>
<head>
<title>Untitled Document</title>
</head>
<body>
<script src="kongjian.js" ></script>
<script>
var a=sx.activex.packmenu.create([["asd","sadsadas"],["sd","sadsaas"],["w","waedqwdq"],["e","efwefw"]]);
//a.contentEditable=true;
document.body.appendChild(a);
</script>
</body>
</html>
搞定,有兴趣的朋友可以看下效果. |
