I am working to add a transparent flash video to a site of a person walking out. The problem is that I don't want the video to play every time the home page is loaded, so I set a 24hr cookie that if detected the div containing the video is set to hide. This works perfectly in Google Chrome and FF, the problem is in IE the div is apparently hidden because you cannot see the video but the audio of the video is still heard. Perhaps there is a different way to do this then the way I am going about it and maybe even a way to do a remove instead of hide? If anyone has any suggestions it would be very much appreciated.

//div that holds the video
<style type="text/css">
#apDiv1 {
position: fixed;
width:560px;
height:314px;
z-index:100;
left: 452px;
top: 316px;
}
</style>

    <script type="text/javascript">
function createC开发者_StackOverflow社区ookie(name,value,days) {
if (days) {
    var date = new Date();
    date.setTime(date.getTime()+(days*24*60*60*1000));
    var expires = "; expires="+date.toGMTString();
}
else var expires = "";
document.cookie = name+"="+value+expires+"; path=/";
}

function readCookie(name) {
var nameEQ = name + "=";
var ca = document.cookie.split(';');
for(var i=0;i < ca.length;i++) {
    var c = ca[i];
    while (c.charAt(0)==' ') c = c.substring(1,c.length);
    if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length,c.length);
}
return null;
}

function eraseCookie(name) {
createCookie(name,"",-1);
}

function setTheDivStyle() {
if(!readCookie('wroteIt')) {
// if cookie not found display the div and create the cookie
document.getElementById("apDiv1").style.display="block";
createCookie('wroteIt', 'wroteIt', 1);  // 1 day = 24 hours persistence
}
else {
// if cookie found hide the div
document.getElementById("apDiv1").style.display="none";
}
}
</script>

</head>
<body onload = "setTheDivStyle()">

<div id="apDiv1"> 
<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" width="560" height="314" id="FLVPlayer">
    <param name="movie" value="FLVPlayer_Progressive.swf" />
    <param name="quality" value="high" />
    <param name="wmode" value="transparent" />
    <param name="scale" value="noscale" />
    <param name="salign" value="lt" />
    <param name="FlashVars" value="&amp;MM_ComponentVersion=1&amp;skinName=Clear_Skin_1&amp;streamName=FL_Spot&amp;autoPlay=true&amp;autoRewind=false" />
    <param name="swfversion" value="8,0,0,0" />
  </object>
</div>

Just write to the div dynamically.

Change the div to be empty

<div id="apDiv1"> </div>

Write the flash from the IF statement. (You could do this using dom)

...
if(!readCookie('wroteIt')) {
// if cookie not found display the div and create the cookie

document.getElementById('apDiv1').innerHTML = '<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" width="560" height="314" id="FLVPlayer">
    <param name="movie" value="FLVPlayer_Progressive.swf" />
    <param name="quality" value="high" />
    <param name="wmode" value="transparent" />
    <param name="scale" value="noscale" />
    <param name="salign" value="lt" />
    <param name="FlashVars" value="&amp;MM_ComponentVersion=1&amp;skinName=Clear_Skin_1&amp;streamName=FL_Spot&amp;autoPlay=true&amp;autoRewind=false" />
    <param name="swfversion" value="8,0,0,0" />
  </object>';
