javascript實(shí)現(xiàn)浮動(dòng)窗口的方法：首先創(chuàng)建HTML文件；然后通過“function showFAd(){…}”方法打開浮動(dòng)廣告；最后通過“function showFloat(){…}”方法實(shí)現(xiàn)打開浮動(dòng)窗口即可。
本文操作環(huán)境：windows7系統(tǒng)、javascript1.8.5版、Dell G3電腦。
javascript怎么實(shí)現(xiàn)浮動(dòng)窗口？
具體如下：
HTML部分：
<!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(biāo)題文檔</title> <style type="text/css"> *{ margin:0; padding:0;} a img{ border:0;} </style> </head> <body> <div style="height:2000px; background:#ccc; display:none;"> </div> <!--div id="floatAd" style=" position:fixed !important; position:absolute; _top:expression(eval(document.documentElement.scrollTop+document.documentElement.clientHeight-this.offsetHeight)); z-index: 2147483647; left: 50%; margin-left: -240px !important; top: 50%; margin-top: -210px !important; background:url(images/onlineSay.jpg) no-repeat; width:487px; height:350px; cursor:pointer;"> <div onclick="closeFAd();" style=" width:26px; height:26px; float:right;"></div> <div style="width:487px; height:320px; float:right;" onclick="open_online();"></div> </div> <div id="floatSide" style=" width:141px; height:579px; position:fixed !important; position:absolute; _top:expression(eval(document.documentElement.scrollTop+document.documentElement.clientHeight-this.offsetHeight)); z-index: 99999; right:0; top:6%; background:url(images/onlineTel.gif);cursor:pointer;" onclick="open_online();></div--> </body> </html> <script type="text/javascript" src="online.js"></script>
JS部分：
// JavaScript Document //浮動(dòng)廣告圖片 var floatAdImg = "images/onlineSay.jpg"; //浮動(dòng)側(cè)欄圖片 var floatSideImg = "images/onlineTel.gif"; //打開在線溝通 function open_online() { window.open('http://p.qiao.baidu.com//im/index?siteid=7342332&ucid=7601325'); } //浮動(dòng)廣告 document.writeln("<div id="floatAd" style=" position:fixed !important; position:absolute; _top:expression(eval(document.documentElement.scrollTop+document.documentElement.clientHeight-this.offsetHeight)); z-index: 2147483647; left: 50%; margin-left: -240px !important; top: 50%; margin-top: -210px !important; background:url("+floatAdImg+") no-repeat; width:487px; height:350px; cursor:pointer; display:none; ">"); document.writeln("<div onclick="closeFAd();" style=" width:26px; height:26px; float:right;"></div>"); document.writeln("<div style="width:487px; height:320px; float:right;" onclick="open_online();"></div>"); document.writeln("</div>"); //浮動(dòng)側(cè)欄 document.writeln("<div style=" width:141px; height:579px; position:fixed !important; position:absolute; _top:expression(eval(document.documentElement.scrollTop+document.documentElement.clientHeight-this.offsetHeight)); z-index: 99999; right:0; top:6%; background:url("+floatSideImg+");cursor:pointer;" onclick="open_online();"></div>"); //關(guān)閉浮動(dòng)廣告 function closeFAd() { document.getElementById('floatAd').style.display = 'none'; } //打開浮動(dòng)廣告 function showFAd() { document.getElementById('floatAd').style.display = 'block'; } //打開浮動(dòng)窗口 function showFloat() { document.getElementById('floatAd').style.display = 'block'; } //打開窗口 20 秒僅執(zhí)行一次 setTimeout(showFAd,20000); //每個(gè) 30 秒執(zhí)行一次 setInterval(showFloat,30000);
效果圖如下：
