浏览器-点击预览视频文件（自动播放、循环播放）
点击预览按钮，弹出窗口自动播放视频文件，并伴有遮罩层
从网上自行下载jquery-1.11.2.min.js（版本自己选择）和flvplayer.swf文件。需要注意的是网上一般有两个版本的flvplayer.swf。
1、第一种flvplayer.swf（将下面的代码嵌套到demo.html中）
<p id="player1">
<script type="text/javascript">
var s1 = new SWFObject("flvplayer.swf","single","1000","600","10");
s1.addParam("allowfullscreen","true");
//文件引用为file
s1.addVariable("file","test1.mp4");
//是否自动播放，true：是，false：否
s1.addVariable("autostart","true");
//是否循环播放，true：是，false：否
s1.addVariable("repeat","true");
s1.addVariable("image","preview.png")
s1.addParam("width","1000");
s1.addParam("height","600");
s1.write("player1");
script>
P>生成的代码为：
<embed type="application/x-shockwave-flash" src="flvplayer.swf" width="1000" height="600" style="undefined" id="single" name="single" quality="high" allowfullscreen="true" flashvars="file=test1.mp4&autostart=true&repeat=true&image=preview.png">embed>效果：
2、第二种flvplayer.swf（将下面的代码嵌套到demo.html中）
<p id="player1">
<script type="text/javascript">
var s1 = new SWFObject("flvplayer.swf","single","1000","600","10");
s1.addParam("allowfullscreen","true");
//文件引用为vcastr_file
s1.addVariable("vcastr_file","test1.mp4");
s1.addVariable("image","preview.png")
//是否自动播放，1：是，0：否
s1.addVariable("IsAutoPlay","1");
//是否循环播放，1：是，0：否
s1.addVariable("IsContinue","1");
s1.addParam("width","1000");
s1.addParam("height","600");
s1.write("player1");
script>
P>生成的代码为：
<embed type="application/x-shockwave-flash" src="flvplayer.swf" width="1000" height="600" style="undefined" id="single" name="single" quality="high" allowfullscreen="true" flashvars="vcastr_file=test1.mp4&IsAutoPlay=1&IsContinue=1&image=preview.png">embed>效果：
需要根据自己所下载的flvplayer.swf判断使用哪种，并注意区别。
