javascript 簡單抽屜效果的實現(xiàn)代碼，需要的朋友可以參考下，大家自行測試。

css

 
<style type="text/css"> 
#bodycontainer 
{ 
height: 66px; 
} 
#leftcontainer 
{ 
background-color: #C5C5C5; 
float: left; 
border: 1px solid #C5C5C5; 
} 
</style> 

aspx:

復(fù)制代碼代碼如下:

 
<div id="bodycontainer"> 
<div id="leftcontainer+<%#Container.ItemIndex+1 %>" style="display:none;"> 
<%#hiSoft.AMS.BLL.BAssetAlteration.getActionLinksString(Eval("ID"), g_Sites, g_Permission)%> 
</div> 
<div> 
<img title="show" alt="open" src="Images/x16.gif" id="showleft+<%#Container.ItemIndex+1 %>" onclick="var leftslider = new slider(this,1,50,85,20,1,20);leftslider.show();this.style.display='none';Show(this);"/> 
<script type="text/javascript"> 
function Show(a) { 
//a.style.display = 'none'; 
document.getElementById(a.parentElement.children[2].id).style.display = ''; 
} 
</script> 
<img title="hidden" alt="close" src="Images/x16.gif" id="hideleft+<%#Container.ItemIndex+1 %>" onclick="var leftslider = new slider(this,1,50,85,20,1,20);leftslider.hide();this.style.display='none';document.getElementById(this.parentElement.children[0].id).style.display='';" style="display:none " /> 
</div> 
</div> 
&nbsp; 

slider.js:

復(fù)制代碼代碼如下:

 
slider.names = new Array(); 
function slider() 
{ 
this.id = slider.names.length; 
slider.names[this.id] = this; 
this.target = document.getElementById(arguments[0].parentElement.parentElement.children[0].id); //第一個參數(shù)：被操作div的id 
this.direction = arguments[1];//第二個參數(shù)：div彈出的方向 
this.height = arguments[2];//第三個參數(shù)：div的高度 
this.width = arguments[3];//第四個參數(shù)：div的寬度 
this.step = arguments[4];//第五個參數(shù)：希望動作分解為幾步完成 
this.timer = 10 * arguments[5];//第六個參數(shù)：每個動作的間隔時間，10ms為一個單位 
this.startopa = arguments[6];//第七個參數(shù)：div開始的透明度 
this.sparent = this.target.parentNode;//獲取操作div的父容器 
this.intervalid = null;//循環(huán)定時的id 
this.i = 0;//循環(huán)的計數(shù)器 
this.status = 0;//slider層的狀態(tài)：0-可以展開；1-不可以展開 
this.target.style.display = "none";//先將div隱去 
return this; 
}
