視頻不會在mediaelement.js上更改

我正在嘗試使用javascript更改mediaelement.js中的視頻。視頻不會在mediaelement.js上更改

我的功能在首次啓動選擇視頻時完美運行。但是，如果我再次調用該函數，它似乎忽略該調用，但新路徑是正確的。當我直接使用HTML5時，會重新加載視頻（請參閱評論的player1.src等），但這不會使用mediaelement.js的優點來實現回退和格式設置。

我忘了什麼？我需要清除以前的實例嗎？如果是這樣的話？

謝謝

<script type='text/javascript'> 

function playVideo(videopath) 
{ 
    var myVideo = document.getElementById(videopath).value; 
    var myVideopath = 「/Library/"+encodeURIComponent(myVideo); 
    // player1.src = myVidiopath; 
    // player1.load(); 
    // player1.play(); 


     var v = document.getElementsByTagName("video")[0]; 
    var player2 = new MediaElementPlayer 
    (v, 
     { 
     success: function(media, domObject)

你應該重用player2對象不能創造新的每次...

<script type='text/javascript'> 
var player2=false; 
    function playVideo(videopath) 
    { 
     var myVideo = document.getElementById(videopath).value; 
     var myVideopath = 「/Library/"+encodeURIComponent(myVideo); 

     var v = document.getElementsByTagName("video")[0]; 
     if (typeof(player2)!='object') 
     { 
     player2 = new MediaElementPlayer(v, { 
      success: function(media, domObject) 
      { 
       media.setSrc(myVidiopath); 
        media.load(); 
        media.play(); 
      } 
     }); 
     } 
     else 
     { 
      player2.setSrc(myVidiopath); 
      player2.load(); 
      player2.play(); 
     } 
    } 
</script>
