本文實例講述了javascript控制層顯示或隱藏的方法。分享給大家供大家參考。具體實現(xiàn)方法如下：
<html><head><title>中國風(fēng)</title><meta http-equiv="Content-Type" content="text/html; charset=gb2312"></head><script language="JavaScript">function showLay1(){ lay1.style.visibility="visible"; lay2.style.visibility="hidden"; lay3.style.visibility="hidden";}function showLay2(){ lay1.style.visibility="visible"; lay2.style.visibility="visible"; lay3.style.visibility="hidden";}function showLay3(){ lay1.style.visibility="visible"; lay2.style.visibility="visible"; lay3.style.visibility="visible";}</script><body><div id="lay1" style="position:absolute; left:60px; top:30px; width:250px; height:200px; index:1; visibility:visible">這是第一層內(nèi)容,它的背景是透明的</div><div id="lay2" style="position:absolute; left:60px; top:30px; width:250px; height:200px; index:2; visibility:hidden; background-color:silver">這是第二層內(nèi)容,它的背景是灰色的</div><div id="lay3" style="position:absolute; left:60px; top:30px; width:250px; height:200px; index:3; visibility:hidden"><br><br><br>這是第三層內(nèi)容,它的背景是透明的</div><form id="form1" style="position:absolute; left:70px; top:250px;"><input type="button" value="第一層" onclick="showLay1()"><input type="button" value="第二層" onclick="showLay2()"><input type="button" value="第三層" onclick="showLay3()"></form></body></html>希望本文所述對大家的javascript程序設(shè)計有所幫助。
