js tab效果的實(shí)現(xiàn)代碼

更新時(shí)間：2009年12月26日 02:40:32 作者：

js之類似tab的實(shí)現(xiàn)，之前已經(jīng)發(fā)布了很多，需要的朋友多看看。

預(yù)實(shí)現(xiàn)效果:(點(diǎn)擊不同的tab顯示不同面板內(nèi)容)

一:用到的js函數(shù):

<script language="javascript" type="text/javascript" > 
//變換tab函數(shù) 
//原則,外層div里含有內(nèi)層多個(gè)div 
function tabPanelEx(trThis,urlImgNormal,urlImgPoint,tabs,tabid){ 
var tds=trThis.parentNode.children; 
for(var i=0;i<tds.length;i++) 
{ 
if(tds[i].attributes["ex"]) 
{ 
tds[i].style.backgroundImage="url("+urlImgNormal+")"; 
} 
} 
trThis.style.backgroundImage="url("+urlImgPoint+")"; 
//div control 
var vtabs=document.getElementById(tabs).children; 
for(var j=0;j<vtabs.length;j++) 
{ 
vtabs[j].style.display="none"; 
} 
document.getElementById(tabid).style.display="block"; 
} 
</script> 

二:頁面調(diào)用代碼;
代碼

復(fù)制代碼代碼如下:

 
<table width="768" border="0" cellspacing="0" cellpadding="0"> 
<!-- tab上方按鈕行 --> 
<tr valign="bottom"> 
<td height="37" background="../images/a_06.jpg"> 
<table border="0" cellspacing="0" cellpadding="0"> 
<tr> 
<td width="16" height="32" valign="bottom"></td> 
<td ex="true" width="94" height="32" align="right" valign="middle" background="../images/an_01.jpg" style="cursor:pointer" 
onClick="tabPanelEx(this,'../images/an_02.jpg','../images/an_01.jpg','newTabs','newsTab1')"> 
<div style="width:72px;height:28px;line-height:28px;text-align:left;" class="bllb14">全員教育 </div></td> 
<td width="7" height="32"></td> 
<td ex="true" width="94" height="32" align="right" valign="middle" background="../images/an_02.jpg" style="cursor:pointer" 
onClick="tabPanelEx(this,'../images/an_02.jpg','../images/an_01.jpg','newTabs','newsTab2')" > 
<div style="width:72px;height:28px;line-height:28px;text-align:left;" class="bllb14">醫(yī)界動(dòng)態(tài) </div></td> 
</tr> 
</table> 
</td> 
</tr> 
<!-- 間隙 --> 
<tr> 
<td height="5" align="center"></td> 
</tr> 
<!-- 對(duì)應(yīng)內(nèi)容 --> 
<tr> 
<td align="center"> 
<div id="newTabs"> 
<div id="newsTab1"> 
<table width="768" border="0" cellspacing="0" cellpadding="0"> 
<tr> 
<td width="384" height="240" align="left" valign="top"><p>全員教育</p> 
</td> 
<td width="1" height="240" background="../images/a_07.jpg"></td> 
<td width="384" height="240" align="right" valign="top">全員教育</td> 
</tr> 
</table> 
</div> 
<div id="newsTab2" style="display:none"> 
<table width="768" border="0" cellspacing="0" cellpadding="0"> 
<tr> 
<td width="384" height="240" align="left" valign="top">醫(yī)界動(dòng)態(tài)</td> 
<td width="1" height="240" background="../images/a_07.jpg"></td> 
<td width="384" height="240" align="right" valign="top">醫(yī)界動(dòng)態(tài)</td> 
</tr> 
</table> 
</div> 
</div> 
</td> 
</tr> 
</table> 

調(diào)用解釋:
(1)使用的為table,table結(jié)構(gòu)為:

復(fù)制代碼代碼如下:

<table border="0" cellspacing="0" cellpadding="0"> 
<tr> 
<td 調(diào)用onClick="tabPanelEx(this,'../images/an_02.jpg','../images/an_01.jpg','newTabs','newsTab1')" 顯示newTabs內(nèi)的newsTab1> 
<div style="width:72px;height:28px;line-height:28px;text-align:left;" class="bllb14">全員教育 </div></td> 
<td 調(diào)用onClick="tabPanelEx(this,'../images/an_02.jpg','../images/an_01.jpg','newTabs','newsTab2')" 顯示newTabs內(nèi)的newsTab2> 
<div style="width:72px;height:28px;line-height:28px;text-align:left;" class="bllb14">醫(yī)界動(dòng)態(tài) </div></td>
