一个html5播放视频的video控件只支持android的默认格式mp4和3gp

代码如下:

<!DOCTYPE html> 
<html xmlns="http://www.w3.org/1999/xhtml"> 
<head> 
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> 
<title></title> 
</head> 
<body> 

<div id="divVideo"></div> 

//因js水平有限,不喜勿喷,全当没事看看,video是html5中的新控件,大家可以看看 

<script type="text/javascript"> 

//mp4是ios、android普遍支持的格式 
function playVideo(opt) { 
if (typeof (opt) == "undefined") { 
alert("请传入必要参数!"); 
return; 
} 
if (typeof (opt.elemt) == "undefined") { 
alert("请指定播放器要插入的对象!"); 
return; 
} 
if (typeof (opt.src) == "undefined") { 
alert("请指定要播放视频的路径!"); 
return; 
} 
var _this = this; 
_this.elemt = opt.elemt; //播放器要插入的对象 
_this.src = opt.src; //视频的URL(必设) 
_this.width = opt.width > 0 ? opt.width + "px" : "100%"; //宽度(默认100%) 
_this.height = opt.height > 0 ? opt.height + "px" : "100%"; //高度(默认100%) 
_this.autoplay = opt.autoplay == "true" ? "autoplay" : ""; //自动播放(true为自动播放) 
_this.poster = opt.poster; //视频封面,播放时的封面图片 
_this.preload = opt.preload == "true" ? "preload" : ""; //预加载(true时启动加载) 
_this.loop = opt.loop == "true" ? "loop" : ""; //循环播放(true时循环播放) 
var str = "<video id='playVideo' controls "; //根据设置的属性的值,拼写video控件 
str += " width='" + _this.width + "' height='" + _this.height + "' " + _this.autoplay + " " + _this.preload + " " + _this.loop + " "; 
if (typeof (_this.poster) != "undefined") { 
str += " poster='" + _this.poster + "' >"; 
} else { 
str += " > "; 
} 
str += " <source src='" + _this.src + "' />"; 
str += "</video>"; 
this.elemt.innerHTML = str; //将str放到要插入的对象中 
} 
playVideo({ 
//所有参数,elemt和src为必填其他看需求怎么要求 
//elemt为播放控件要插入的容器,src为视频文件地址,preload为预加载,autoplay是否页面进入就自动播放 
//poster为播放前的遮照图片,loop为是否循环播放,width和heigth默认100% 
elemt: document.getElementById("divVideo"), 
src: "3.mp4", 
preload: "true", 
autoplay: "true", 
poster: "", 
loop: "true", 
width: "", 
heigth:"" 
}); 
</script> 
</body>
