replace image with a video embeded

问题:

Hi I'm trying to modify a web page so that it loads faster. Since I have some videos embeded (blip.tv but can change it to youtube if it helps) I was wondering if you could load an image where the video should be and on click replace the image with the video and start playing (without reloading the whole page). I think I've seen this before, but can't find it anywhere anymore! right now the code to embed I use is:

<object data="http://blip.tv/play/gYMo_vAmAA" type="application/x-shockwave-flash" height="500" width="600"><param name="src" value="http://blip.tv/play/gYMo_vAmAA"><param name="allowfullscreen" value="true"></object>

Thanks

Quick and dirty: you could just set the embed code as a global variable somewhere:

<script type="text/javascript">
    var embedCode = '<object data="http://blip.tv/play/gYMo_vAmAA" type="application/x-shockwave-flash" height="500" width="600"><param name="src" value="http://blip.tv/play/gYMo_vAmAA"><param name="allowfullscreen" value="true"></object>'
</script>

Then put the image in a container div and replace the container's innerHTML onclick:

<div id="videocontainer">
    <img src="yourimage.jpg" onclick="document.getElementById('videocontainer').innerHTML = embedCode;" height="500" width="600" />
</div>

There's a Google code project called SWFObject, which is perfect for what you need. It's a cross-browser javascript library for loading flash - and you could use it to replace your image with the flash video when someone clicks on the image, for example.
