為窗口添加滾動條事件其實非常的簡單， window.onscroll=function(){}; 註意在獲取滾動條距離的時候 谷歌不識別document.documentElement.scrollTop，必須要加上document.body.scrollTop；即 var scrolltop=document.documentElement.scrollTop||document.body.scrollTop; 這樣才能兼容各個瀏覽器！ <!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>無標題文檔</title> <style type="text/css"> #box{ height:50px; width:200px; background:#666; position:absolute; left:0px; top:0px;} </style> </head> <body style="height:9000px;"> <div id="box"></div> <script language="javascript"> window.onscroll = function(e){ var e =e || window.event; var scrolltop=document.documentElement.scrollTop||document.body.scrollTop; var box = document.getElementById(‘box‘); box.style.top= scrolltop+‘px‘; //console.log(scrolltop); } </script> </body> </html>
