本文实例讲述了Javascript实现div层渐隐效果的方法。分享给大家供大家参考。具体实现方法如下:
<!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>Test Alpha</title><style type="text/css">#show {background:#ffff66;font-size:12px;height:200px;width:300px;left:300px;position:absolute;text-align:center;filter:alpha(opacity=0);}</style></head><body onload={document.getElementById("show").style.opacity=0;}><div id="show"></div><button onclick=fun()>button</button></body><script>function fun(){var div=document.getElementById("show"); div.style.opacity=1; hidden(document.getElementById("show"),1,-0.01);}function hidden(o,i,s){t=setInterval(function(){i+=s;o.style.opacity=i;if(i<0)window.clearInterval(t); },1);};</script></html>希望本文所述对大家的javascript程序设计有所帮助。
