Flash视频广告的定位兼容性问题

来源：互联网发布：手机热点软件编辑：程序博客网时间：2024/05/21 06:00

在项目中，用到了一个Flash视频广告，但是该视频广告在Firefox中显示实在是差强人意，居然漂浮在了网站的左上角，该怎么解决这个问题呢？

调用代码如下：
<!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>无标题文档</title>
<script language="javascript" type="text/javascript" src="flash.js"></script>
<style type="text/css">
body { height:1000px;width:100%}
.zhans_ship{ width:250px; height:200px; Z-INDEX:99999; right: 0px; VISIBILITY:hidden; BORDER-BOTTOM: #000 2px solid; POSITION: absolute;BACKGROUND-COLOR: #000;top:378px;}
.top_ship { width:250px; height:26px; background-image:url(kkkk/msgTopBg.gif);font-family:"宋体"; font-size:12px; color:#FFFFFF;}
.top_ship div { width:150px; height:auto; float:left; line-height:20px;}
.bfq_a{font-size: 12px; background-image: url('kkkk/bomBg.gif');height:15px;line-height:15px; color: #ffffff;padding-top:2px; text-align:center;}
.bfq_a a:link { font-family:"宋体"; font-size:12px; text-decoration:none; color:#FFFFFF;}
.bfq_a a:visited { font-family:"宋体"; font-size:12px; text-decoration:none; color:#FFFFFF;}
.bfq_a a:active { font-family:"宋体"; font-size:12px; text-decoration:none; color:#FFFFFF;}
.bfq_a a:hover { font-family:"宋体"; font-size:12px; text-decoration:none; color:#FFFFFF;}
</style>
</head>

<body>
<div class="zhans_ship" id="eMeng">
<divclass="top_ship"><div>视频广告：</div><span title=关闭style="CURSOR:hand;color:white;font-size:12px;font-weight:bold;margin-right:4px;float:right; width:auto; height:auto; margin-top:3px;"onclick=closeDiv() >×</span></div>

<div class="mid_ship">
<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,29,0" width="250" height="150">

</object>
</div>

<div class="bfq_a"><a href="#" target="_blank">大型XX活动</a></div>
</div>
</body>
</html>

flash.js代码（修改后的）如下：

if(document.all){
window.attachEvent('onload',getMsg);
}else{
window.addEventListener('load',getMsg,false);
}
window.onresize = resizeDiv;
window.onerror = function(){}

var divTop,divLeft,divWidth,divHeight,docHeight,docWidth,objTimer,i = 0;

}

function closeDiv()
{
    var eMeng = document.getElementById("eMeng");
    eMeng.innerHTML='';
    eMeng.style.visibility='hidden';
    if(objTimer) window.clearInterval(objTimer);
}

/**
* 获取屏幕宽度的函数，在非xhtml标准页面下有可能有问题
*/
function getWidth()
{
var winWidth = '';
if (window.innerWidth)//for Firefox
{
      winWidth = window.innerWidth;
}
else if((document.body) && (document.body.clientWidth))
{
      winWidth = document.body.clientWidth;
}
if (document.documentElement && document.documentElement.clientWidth)
{
      winWidth = document.documentElement.clientWidth;
}
return winWidth;
}

/**
* 获取屏幕高度的函数
* html,body高度属性必须设值为height:100%否则在火狐浏览器下获取不到真实高度
*/
function getHeight()
{
var winHeight = '';
if (window.innerHeight)//for Firefox
{
      winHeight = window.innerHeight;
}
else if((document.body) && (document.body.clientHeight))
{
      winHeight = document.body.clientHeight;
}

if (document.documentElement && document.documentElement.clientHeight)
{
winHeight = document.documentElement.clientHeight;
}
return winHeight;
}

*:红色部分为修改的位置或添加的代码
修改部分:
1.增强型的获取窗口长度和宽度的函数;
2.在style.top,style.left等处在Firefox下必须使用单位px;
3.调整 Flash参数之wmodel，即window model，详情请自己搜索;

修改以上几处，就可以实现IE，Firefox的准确定位和相同的显示效果。
