我有FF,Chrome,IE,Opera和Safari的5个插件/扩展.

如何识别用户浏览器并重定向(单击安装按钮后)以下载相应的插件？

我正在尝试让视频像YouTube一样播放和暂停(使用播放和暂停按钮,然后单击视频本身.)

<video width="600" height="409" id="videoPlayer" controls="controls">
 <!-- MP4 Video -->
 <source src="video.mp4" type="video/mp4">
</video>


<script>
    var videoPlayer = document.getElementById('videoPlayer');

    // Auto play, half volume.
    videoPlayer.play()
    videoPlayer.volume = 0.5;

    // Play / pause.
    videoPlayer.addEventListener('click', function () {
        if (videoPlayer.paused == false) {
            videoPlayer.pause();
            videoPlayer.firstChild.nodeValue = 'Play';
        } else {
            videoPlayer.play();
            videoPlayer.firstChild.nodeValue = 'Pause';
        }
    });
</script>

你有什么想法会破坏播放和暂停控制按钮吗？

,嗨,

    <!DOCTYPE html> 
<html> 
<body> 

<div style="text-align:center"> 
  <button onclick="playPause()">Play/Pause</button>

  <video id="video1" width="420">

    Your browser does not support HTML5 video.
  </video>
</div> 

<script> 
var myVideo=document.getElementById("video1"); 

function playPause()
{ 
if (myVideo.paused) 
  myVideo.play(); 
else 
  myVideo.pause(); 
} 

function makeBig()
{ 
myVideo.width=560; 
} 

function makeSmall()
{ 
myVideo.width=320; 
} 

function makeNormal()
{ 
myVideo.width=420;

任何帮助将不胜感激.
