这个代码是写在了JS里面。
以下是页面的调用
<div style="height:450px;">
<input type="hidden" id="ctl00_ContentPlaceHolder1_ctl00_ContentPlaceHolder1_videourl" runat="server" value="" checktag="ctl00_ContentPlaceHolder1_videourl" />
<script type="text/javascript">
var url = $("input[checktag='ctl00_ContentPlaceHolder1_videourl']").val();
mediaPlayer(url,560,420);
</script>
</div>
现在只能播放FLV格式的视频。请问我该怎么解决。。在线坐等答案。
[解决办法]
测试了一下，播放器代码是正常的。不能播放有几个原因：
1.客户没有安装浏览器所需的播放插件。注意：因为不同浏览器的插件机制不同，即使安装了播放软件，如果它只支持IE而不支持FF,CHROME，也无法调用播放。这个需要提示用户去安装插件，在网站里提供下载。
2.客户的浏览器设置禁止或限制了视频播放。这个需要告诉用户怎么去检查和解除禁制。
另外可以试试换用百度影音的播放代码，现在它的装机量不少，而且它本身已经支持多种视频格式的插件，所以几乎可以把上面的播放代码合并成只用一种百度影音就可以了。
3. 广告过滤。
另外HTML5对视频也简化成了：
<embed src="" id="theforever_csdn"></embed>
用JS只要
document.getElementById('theforever').src="新视频地址";
就可以了。
