本文實例講述了JavaScript實現多個重疊層點擊切換效果的方法。分享給大家供大家參考。具體如下:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>三個層重疊,點擊可切換</title> <script type="text/javascript"> function $(obj){ return document.getElementById(obj); } function change(n){ for (var i=1;i<4;i++){ if(n==i){ $("a"+i).style.zIndex="100"; }else{ $("a"+i).style.zIndex="0"; } } } </script> </head> <body> <div id="a1" style="position:absolute;left:100px;top:100px;width:100px;height:100px; background-color:#ddeeff;z-index:1" onclick="change('1')" > </div> <div id="a2" style="position:absolute;left:150px;top:130px;width:100px;height:100px; background-color:#eeffdd;z-index:2" onclick="change('2')"> </div> <div id="a3" style="position:absolute;left:200px;top:160px;width:100px;height:100px; background-color:#ffddee;z-index:3" onclick="change('3')"> </div> <div>http://www.jb51.net/</div> </body> </html>
希望本文所述對大家的javascript程序設計有所幫助。
