    Question (**SOLVED**) Why am i getting errors???

    ok i have a code that pulls data out from a xml file, once pulled i have the javascript parse it to the page, that all works, now i need it to have add a link to refer to another javascript function.

    The problem is this.

    My code works fine like this:
    Code:
    <script type="text/javascript">
    function changemusic(id) {
    
    xmlDoc=loadXMLDoc('changemusic.php?id='+id);
    var playlist_div=document.getElementById("playlist");
    playlist_div.innerHTML='';
    
    
    var x=xmlDoc.getElementsByTagName('artist');
    var k=xmlDoc.getElementsByTagName('title');
    var j=xmlDoc.getElementsByTagName('java');
    for (i=0;i<x.length;i++)
      {
    var artist=(x[i].childNodes[0].nodeValue)
    var title=(k[i].childNodes[0].nodeValue) 
    var java=(j[i].childNodes[0].nodeValue)
    
     
    document.getElementById("playlist").innerHTML +=artist+' - '+title+'<input type=button  value=play><br>';
     }
    
    }
    </script>
    Butonce i add the onclick command to the button i recieve errors
    Code:
    <script type="text/javascript">
    function changemusic(id) {
    
    xmlDoc=loadXMLDoc('changemusic.php?id='+id);
    var playlist_div=document.getElementById("playlist");
    playlist_div.innerHTML='';
    
    
    var x=xmlDoc.getElementsByTagName('artist');
    var k=xmlDoc.getElementsByTagName('title');
    var j=xmlDoc.getElementsByTagName('java');
    for (i=0;i<x.length;i++)
      {
    var artist=(x[i].childNodes[0].nodeValue)
    var title=(k[i].childNodes[0].nodeValue) 
    var java=(j[i].childNodes[0].nodeValue)
    
     
    document.getElementById("playlist").innerHTML +=artist+' - '+title+'<input type=button value onclick='+java+'><br>';
     }
    
    }
    </script>
    Here is all related code:

    here is a link to my page

    http://www.music.friendshideout.com/desktopplayer.php

    you will need to register in order to view, the register page will open in a seperate window, once registered you can exit and login, you will see my picture as i am an instant friend, click on it and a list of songs will be displayed, when i click play is when i recieve the errors.


    it comes up with errors only when i add onclick="somefunction();"

    i have even tried making up a basic function to display data in a div and i still recieve errors. Here is the whole code

    desktopplayer.php:
    Code:
    
    
    <html>
    <head>
    
    
    
    
    <script type="text/javascript" src="loadxmldoc.js"> 
    <script type="text/javascript">
    
    function song(what,who){
    document.getElementById("music1").innerHTML='<object id="mediaplayer1" width="200" height="45" classid="CLSID:6BF52A52-394A-11d3-B153-00C04F79FAA6" type="application/x-oleobject"><param name="URL" value="'+what+'"><param name="AutoStart" VALUE="True"><param name="uiMode" value="full"><embed type="application/x-mplayer2" src="'+what+'" ShowControls="1" AutoStart="1" width="200" height="45"></embed></object>';
    nowplaying(who);
    return false;
    }
    
    function nowplaying(who)
    {
    document.getElementById("playing").innerHTML='<font color="blue"><h4>Now Playing '+who;
    		
    	
    }
    
    
    
    function changemusic(id) {
    
    xmlDoc=loadXMLDoc('changemusic.php?id='+id);
    var playlist_div=document.getElementById("playlist");
    playlist_div.innerHTML='';
    
    
    var x=xmlDoc.getElementsByTagName('artist');
    var k=xmlDoc.getElementsByTagName('title');
    var j=xmlDoc.getElementsByTagName('java');
    var playlist = document.getElementById("playlist");
    for (i=0;i<x.length;i++)
      {
    var artist=(x[i].childNodes[0].nodeValue);
    var title=(k[i].childNodes[0].nodeValue) ;
    var java=(j[i].childNodes[0].nodeValue);
    
    
    
    
     
    document.getElementById("playlist").innerHTML +=artist+' - '+title+'<input type="button" value="Play" onclick="'+java'+"><br>';
    
     }
    
    }
    </script>
    
    
    
    
    
    
    
    
    
    
    
    
    </head>
    <body>
    <?
    
    
    
    
    echo"<center>Welcome $displayname";
    
    
    
    
    
    echo"<table><tr><td width='500' colspan=2><br><div id='playing'></div>";
    
    echo"

    echo"<table><tr><td colspan=10>Listen To Friends Music</td></tr>";
    
    
    
    
    
    
    
    
    $data1 = mysql_query("SELECT * FROM friends WHERE user_id='$id' LIMIT 10") 
    or die(mysql_error()); 
    while($info1 = mysql_fetch_array( $data1 )) { 
    
    
    $friendid=$info1['friend_id'];
    
    $data = mysql_query("SELECT * FROM users WHERE user_id='$friendid'") 
    or die(mysql_error()); 
    while($info = mysql_fetch_array( $data )) {
    
     
     $display=$info['display_name'];
     $photo=$info['default_photo'];
     $online=$info['online'];
    
    
    
    
    ?><td valign=top><center><a href='#' style="text-decoration:none;" onclick="changemusic('<? echo"$friendid";?>');">
    <?
    echo "<font color='blue'>$display<br>";
    
    Print "<img src='$photo' height='75' width='75' border='0'></a>"; 
    //display if user is online
    if ($online=='0') {
    echo"</font></td>";
    }
    else
    {
    echo "<br><img src='http://www.friendshideout.com/images/online.gif'></font></td>";
    }
    }
    
    }
    here is loadxmldoc.js
    Code:
    function loadXMLDoc(dname)
    {
    var xmlDoc;
    // code for IE
    if (window.ActiveXObject)
    {
    xmlDoc=new ActiveXObject("Microsoft.XMLDOM");
    }
    // code for Mozilla, Firefox, Opera, etc.
    else if (document.implementation && document.implementation.createDocument)
    {
    xmlDoc=document.implementation.createDocument("","",null);
    }
    else
    {
    alert('Your browser cannot handle this script');
    }
    xmlDoc.async=false;
    xmlDoc.load(dname);
    return(xmlDoc);
    }
    and changemusic.php:

    (this is where the value for java comes from)
    Code:
    $xml = '<?xml version="1.0" ?><root>';
    $data2 = mysql_query("SELECT * FROM music WHERE user_id='$userid' ORDER BY artist ASC") 
    or die(mysql_error()); 
    while($info2 = mysql_fetch_array( $data2 )) {
    
    
    
    
    //Pull data from database about that user
    
    $songid="".$info2['song_id'] . "";
    $source="".$info2['source'] . "";
    $artist="".$info2['artist'] . "";
    $title="".$info2['title'] . "";
    
    
    
    //Display 5 most recent blogs
    
    $xml .= '<song id="' . $songid . '">';
    $xml .= "<artist>" . $artist . "</artist>";
    $xml .= "<java>song('" . $source . "','" . $artist . " - " . $title . "')</java>";
    $xml .= '<title>' . $title . '</title>';
    $xml .= '<source>' . $source . '</source>';
    $xml .= '</song>';
    
    
    }
    $xml .= '</root>';
    echo $xml;
    That is all code related to that page. Hope this helps

    innerHTML is not a standard method. It is a crossbrowser one, it is true, but it is useful only in case you want simply to change the layout. If you need to really create/append/remove dynamically new elements and to attach events to them, you should use DOM standard methods createElement(), appendChild().... and so on.

    On the other hand, to create an event handler for an element, you may use DOM 0 level syntax and an anonymous

    element.onclick=function(){myFunction(arguments)}
