    Applying javascript to only one table in a html file

    I have some javascript which applies alternative row colors to a table and also gives you a highlight effect when you mouseover the rows.

    However, the problem I have is that it applies to every table on my page, I only want it to apply to a specific table in the html file (I'm using frontpage), not all of them

    How would I go about doing this? The code is below, it has a bit of styling at the top before the javascript.

    Code:
    <style type="text/css" media="all">
    table.altsrowtable { width: 90%; margin: auto; border-collapse: collapse}
    td { border: 1px solid black; cursor:pointer;text-align:center}
    /* row 1 */
    tr td { background: #edf3fe; }
    tr:hover td, tr.ie td { background: #e1e1ff; }
    /* row 2 */
    tr.bis td { background: #D9ECFF; }
    tr.bis:hover td, tr.bisie td { background: #e1e1ff; }
    /* selected row 1 */
    tr.sel:hover td, tr.selie td { background: #edf3fe; }
    /* selected row 2 */
    tr.selbis:hover td, tr.selbisie td { background: #D9ECFF; }
    </style>
    <script type="text/javascript" span="altsrowtables" div="altsrowtable" id="altsrowtable" class="altsrowtable">
    
    var IE = false; /*@cc_on IE=true; @*/
    
    var r;
    
    function setRows(){
    r = document.getElementsByTagName('TR');
    for(var i=0;i<r.length;i++)
    r[i].className = (i/2 != Math.round(i/2))? '':'bis';
    }
    
    function selectRow(aRow,add){
    var c = aRow.className;
    if(add) setRows();
    var b = aRow.className;
    if(IE)
    aRow.className =
    b==''? 'selie' :
    b=='bis'? 'selbisie' :
    c=='selie'? 'ie' :
    c=='ie'? 'selie' :
    c=='bisie'? 'selbisie' :
    c=='selbisie'? 'bisie' :
    '';
    else
    aRow.className =
    b==''||c==''? 'sel' :
    b=='bis'||c=='bis'? 'selbis' :
    c=='selbis'? 'bis' :
    '';
    }
    // roll-over (only for IE)
    function roll(what) {
    var c = what.className;
    what.className = c==''? 'ie' :
    c=='bis'? 'bisie' :
    c=='bisie'? 'bis' :
    c=='selbis'? 'selbisie' :
    c=='selbisie'? 'selbis' :
    c=='selie'? 'sel' :
    c=='sel'? 'selie' :
    '';
    }
    // fire on loading
    onload= function() {
    setRows();
    for(var i=0;i<r.length;i++) {
    
    if(IE) {
    r[i].onmouseover = function(){ roll(this); }
    r[i].onmouseout = function(){ roll(this); }
    }
    }
    }
    
    </script>
    <style type="text/css">
    table.altrowstable {
    	font-family: calibri;
    	font-size:11px;
    	color:#333333;
    	border-width: 1px;
    	border-color: #C0C0C0;
    	border-collapse: collapse;
    }
    table.altrowstable th {
    	border-width: 1px;
    	"background-image:url('QP Header.png');"
    	border-style: solid;
    	border-color: #C0C0C0;
    	font-size:12px;
    	font-style:bold;
    }
    table.altrowstable td {
    	border-width: 1px;
    	
    	border-style: solid;
    	border-color: #a9c6c9;
    }
    </style>
    Thanks
    Sean

    WOW thats some intense code for just Zebra striping...

    Obviously you've done a chuck of working rigging this up, but you may want to look into this method. it will keep things a lot cleaner for you so down the line changes can be made in no time.
