    asx playlist loaded dynamically, but links won't work.

    I currently found a script that dynamically loads an ASX playlist, allowing the user to choose the item that he wants to watch in Windows media player embedded.
    The trouble is that once the user click on the link in the playlist it wont work.
    Take a look here http://tv.mghospedagem.com/wmp-pl3.html

    Works only on IE.


    Code:
    <head>
<script language="javascript1.2">

playListLoaded=false;


function loadPlayItems() {
        df=document.getElementById("playItem");
        dp=document.getElementById("playlist");
        WMP9=document.getElementById("MediaPlayer1");

WMP9.url="http://tv.mghospedagem.com/play.asx";
        WMP9.controls.play();

}

function showPlayItems() {
        WMP9=document.getElementById("MediaPlayer1");
        playlistItems=WMP9.currentPlaylist.count;
        for (i=0; i<playlistItems; i++) {
                playitem=document.createElement("a");
                playnext=document.createElement("br");
                playitem.setAttribute("href","#");
                playitem.setAttribute("onclick","playItem("+i+")");
                playitem.innerText=WMP9.currentPlaylist.item(i).name;
                dp.appendChild(playitem);
                dp.appendChild(playnext);
        }
        playListLoaded=true;
        WMP9.controls.play();

}



function setPlayItem(index) {
        WMP9=document.getElementById("MediaPlayer1");
        playlistItems=WMP9.currentPlaylist.count;
        if (playlistItems > 0) {

WMP9.controls.currentItem=WMP9.currentPlaylist.item(index);
                WMP9.controls.play();
        }
}

</script></head>

<body onLoad="loadPlayItems()">
<object id="MediaPlayer1"
classid="clsid:6BF52A52-394A-11D3-B153-00C04F79FAA6"

</object>

<div id="playlist" style="position: absolute; top: 10px; left:
640px; visibility: visible; z-index: 999999999999999;">
<h2>Playlist</h2></div>

<script language="javascript1.2" for="MediaPlayer1"
event="playStateChange">
WMP9=document.getElementById("MediaPlayer1");
if (WMP9.playState==3 && ! playListLoaded) {
        showPlayItems();
}

      That's the first time that anyone help me here. That script problem must be a really hard issue to solve.

          So, how can I use this information to help on my issue?

          The following text is from another source:



          Hi Chopz,

          That's an interesting hack, but it relies on browser sniffing, which is best avoided if possible. There are a couple of other solutions to this problem, the simplest is to add event.returnVal ue = false to make it work in IE:
          Code:
          <a href="#" onclick="doSomething(); event.returnValue = false; return false;">click me</a>
          And then there is the much more convoluted but more OOP method of attaching events at onLoad (which of course requires harvesting the element/s to change and using different methods for IE and everyone else):

          Code:
          function preventDefaultAction(evt) {
   if (evt) {
      if (typeof evt.preventDefault!= 'undefined') {
         evt.preventDefault(); // W3C
      } else {
         evt.returnValue = false; // IE
      }
   }
   // safey for handling DOM Level 0
   return false;
}

function doSomething(evt) {
   alert('do something cool');
   return preventDefaultAction(evt);
}
function init() {
   var target = document.getElementById('target');
    if (target.addEventListener) { // use addEventListener for DOM
       target.addEventListener('click', doSomething, false);
    } else if (target.attachEvent) { // use attachEvent for IE
       target.attachEvent('onclick', doSomething);
    }
}

          and the HTML


          Code:
          <body onLoad="init()">
   <div id="scrollbox"></div>
   <p>If you have JS enabled, the page should not scroll to the top when you <a id="target" href="#">click this link</a>.</p>
</body>
          HTH, Scott

                  playItem() needs to be a function and I don't see it anywhere. Also, I would avoid naming elements and functions with the same name.

                  PS. merged threads.

                      Hi sir, what do you mean with "playItem() needs to be a function and I don't see it anywhere"?

                      U mean that the funcition is not being used by Internet Explorer anymore?

                      ----- EDITING ----

                      I'm sorry, I've read "anymore", instead of "anywhere".

                          The line which is causing problems:
                          Code:
                          playitem.setAttribute("onclick","playItem("+i+")");
                          translates as onclick="playIt em(0)", onclick="playIt em(1)" and so on depending on the number of items in the play list.

                                  So it will be like this?

                                  Code:
                                  function showPlayItems() {
        WMP9=document.getElementById("MediaPlayer1");
        playlistItems=WMP9.currentPlaylist.count;
        for (i=0; i<playlistItems; i++) {
                playitem=document.createElement("a");
                playnext=document.createElement("br");
                playitem.setAttribute("href","javascript:void(0)");
                onclick="playItem("+i+")";
                playitem.innerText=WMP9.currentPlaylist.item(i).name;
                dp.appendChild(playitem);
                dp.appendChild(playnext);
        }
        playListLoaded=true;
        WMP9.controls.play();
 
}

                                          No, it can't be like that. If anything, it'd be something like:
                                          Code:
                                          playitem.onclick = function() { playItem(i) };
                                          This will still not work because you haven't defined the function playItem().

                                          You mention about not being able to use numbers. Well, then you need to tell us exactly what you can use.

                                              I mentioned number because there is an +i+, I didnt see any zero, or one, 2, 3. So I thought the developer used that to show that the script will play only what is loaded dynamicaly from the P LIst.

                                                  If you follow the code, you'll see that i is in fact a variable counter holding a number - see this line:
                                                  Code:
                                                  for (i=0; i<playlistItems; i++) {
                                                  It starts at 0 until the number of play list items.

                                                  Anyway, until you don't define playItems as a function, it's simply not going to work and you should see errors in your error console.

                                                          OK, that's not correct. Before we proceed any further, where did you get the original code from or did you write it yourself?
