    Javascript class changing, colspan, firefox

    I am having some issues with firefox, that work fine in IE (go figure)

    The issue is, I have a table with 4 tds on the the title bar (one blank) and three (one displayed at a time) tr's with 1 td and a colspan=4.

    It displays fine at pageload, but when I dynamically change the display from none to block, it resets the colspan to 1 (atleast it displays that way).

    again, this works fine in IE6+, just not firefox.

    thanks in advance.


    Code:
    <script>
    function swapInbox(boxx){
    	switch(boxx){
    		case "1":
    			document.getElementById('trOldMail').style.display = "none";
    			document.getElementById('tdOldMailHeader').className = "mailNotSelected";
    			document.getElementById('trSavedMail').style.display = "none";
    			document.getElementById('tdSavedMailHeader').className = "mailNotSelected";
    			document.getElementById('trNewMail').style.display = "block";
    			document.getElementById('tdNewMailHeader').className = "mailSelected";
    		break;
    		case "2":
    			document.getElementById('trOldMail').style.display = "block";
    			document.getElementById('tdOldMailHeader').className = "mailSelected";
    			document.getElementById('trSavedMail').style.display = "none";
    			document.getElementById('tdSavedMailHeader').className = "mailNotSelected";
    			document.getElementById('trNewMail').style.display = "none";
    			document.getElementById('tdNewMailHeader').className = "mailNotSelected";
    		break;
    		case "3":
    			document.getElementById('trOldMail').style.display = "none";
    			document.getElementById('tdOldMailHeader').className = "mailNotSelected";
    			document.getElementById('trSavedMail').style.display = "block";
    			document.getElementById('tdSavedMailHeader').className = "mailSelected";
    			document.getElementById('trNewMail').style.display = "none";
    			document.getElementById('tdNewMailHeader').className = "mailNotSelected";
    		break;
    	}
    	return true;
    }
    </script>
    <table style="width:550px;" cellspacing="0" cellpadding="5"><tr>
    <td class="mailSelected" id="tdNewMailHeader" onclick="return swapInbox('1');">New Mail</td>
    <td class="mailNotSelected" id="tdOldMailHeader" onclick="return swapInbox('2');">Old Mail</td>
    <td class="mailNotSelected" id="tdSavedMailHeader" onclick="return swapInbox('3');">Saved Mail</td>
    <td class="mailFiller"></td>
    </tr>
    
    <tr id="trNewMail" class="trShowMessages">
    <td id="tdMailNew" class="mailDisplay" colspan="4">ewewew</td>
    </tr>
    
    <tr id="trOldMail" style="display:none;" class="trShowMessages">
    <td id="tdMailOld" class="mailDisplay" colspan="4">sdsdsds</td>
    </tr>
    
    <tr id="trSavedMail" style="display:none;" class="trShowMessages">
    <td id="tdMailSaved" class="mailDisplay" colspan="4">gfgfgf</td>
    </tr>
    
    </table>


    here is the css, incase it has an impact:
    Code:
    /***********************
           MAIL BOX
    ***********************/
    .mailSelected{
    	width:100px;
    	max-width:100px;
    	background-color:#0099CC;
    	color:#FFFFFF;
    	text-align:center;
    	cursor:pointer;
    	font-weight:bold;
    }
    .mailNotSelected{
    	width:100px;
    	max-width:100px;
    	background-color:#DDDDDD;
    	color:#000000;
    	text-align:center;
    	cursor:pointer;
    }
    .mailFiller{
    	background-color:#DDDDDD;
    	width:250px;
    }
    .mailDisplay{
    	border:1px solid;
    	border-color:#0099CC;
    	padding:10px;
    	width:550px;
    }
    .mailMessage{
    	border:1px solid;
    	border-color:#0099CC;
    	padding:10px;
    	
    }
    .trShowMessages{
    	width:550px;
    }

    Use "display:table-row" instead of "display:block"


    Code:
    <script>
    function swapInbox(boxx){
    	switch(boxx){
    		case "1":
    			document.getElementById('trOldMail').style.display = "none";
    			document.getElementById('tdOldMailHeader').className = "mailNotSelected";
    			document.getElementById('trSavedMail').style.display = "none";
    			document.getElementById('tdSavedMailHeader').className = "mailNotSelected";
    			document.getElementById('trNewMail').style.display = "table-row";
    			document.getElementById('tdNewMailHeader').className = "mailSelected";
    		break;
    		case "2":
    			document.getElementById('trOldMail').style.display = "table-row";
    			document.getElementById('tdOldMailHeader').className = "mailSelected";
    			document.getElementById('trSavedMail').style.display = "none";
    			document.getElementById('tdSavedMailHeader').className = "mailNotSelected";
    			document.getElementById('trNewMail').style.display = "none";
    			document.getElementById('tdNewMailHeader').className = "mailNotSelected";
    		break;
    		case "3":
    			document.getElementById('trOldMail').style.display = "none";
    			document.getElementById('tdOldMailHeader').className = "mailNotSelected";
    			document.getElementById('trSavedMail').style.display = "table-row";
    			document.getElementById('tdSavedMailHeader').className = "mailSelected";
    			document.getElementById('trNewMail').style.display = "none";
    			document.getElementById('tdNewMailHeader').className = "mailNotSelected";
    		break;
    	}
    	return true;
    }
    </script>

    this works in both:
    Code:
    <script>
    function swapInbox(boxx){
    	switch(boxx){
    		case "1": 
    			document.getElementById('trOldMail').style.display = "none";
    			document.getElementById('tdOldMailHeader').className = "mailNotSelected";
    			document.getElementById('trSavedMail').style.display = "none";
    			document.getElementById('tdSavedMailHeader').className = "mailNotSelected";
    			document.getElementById('trNewMail').style.display = "";
    			document.getElementById('tdNewMailHeader').className = "mailSelected";
    		break;
    		case "2":
    			document.getElementById('trOldMail').style.display = "";
    			document.getElementById('tdOldMailHeader').className = "mailSelected";
    			document.getElementById('trSavedMail').style.display = "none";
    			document.getElementById('tdSavedMailHeader').className = "mailNotSelected";
    			document.getElementById('trNewMail').style.display = "none";
    			document.getElementById('tdNewMailHeader').className = "mailNotSelected";
    		break;
    		case "3":
    			document.getElementById('trOldMail').style.display = "none";
    			document.getElementById('tdOldMailHeader').className = "mailNotSelected";
    			document.getElementById('trSavedMail').style.display = "";
    			document.getElementById('tdSavedMailHeader').className = "mailSelected";
    			document.getElementById('trNewMail').style.display = "none";
    			document.getElementById('tdNewMailHeader').className = "mailNotSelected";
    		break;
    	}
    	return true;
    }
    </script>

    Not sure if Safari or Chrome supports too.
    Anyway here is one another working version too.

    Code:
    <script>
    function getInternetExplorerVersion()
    // Returns the version of Internet Explorer or a -1
    // (indicating the use of another browser).
    {
      var rv = -1; // Return value assumes failure.
      if (navigator.appName == 'Microsoft Internet Explorer')
      {
        var ua = navigator.userAgent;
        var re  = new RegExp("MSIE ([0-9]{1,}[\.0-9]{0,})");
        if (re.exec(ua) != null)
          rv = parseFloat( RegExp.$1 );
      }
      return rv;
    }
    
    function swapInbox(boxx){
    	var display = ((getInternetExplorerVersion()>=5)&&(getInternetExplorerVersion()<8))?"block":"table-row";
    	switch(boxx){
    		case "1":
    			document.getElementById('trOldMail').style.display = "none";
    			document.getElementById('tdOldMailHeader').className = "mailNotSelected";
    			document.getElementById('trSavedMail').style.display = "none";
    			document.getElementById('tdSavedMailHeader').className = "mailNotSelected";
    			document.getElementById('trNewMail').style.display = display;
    			document.getElementById('tdNewMailHeader').className = "mailSelected";
    		break;
    		case "2":
    			document.getElementById('trOldMail').style.display = display;
    			document.getElementById('tdOldMailHeader').className = "mailSelected";
    			document.getElementById('trSavedMail').style.display = "none";
    			document.getElementById('tdSavedMailHeader').className = "mailNotSelected";
    			document.getElementById('trNewMail').style.display = "none";
    			document.getElementById('tdNewMailHeader').className = "mailNotSelected";
    		break;
    		case "3":
    			document.getElementById('trOldMail').style.display = "none";
    			document.getElementById('tdOldMailHeader').className = "mailNotSelected";
    			document.getElementById('trSavedMail').style.display = display;
    			document.getElementById('tdSavedMailHeader').className = "mailSelected";
    			document.getElementById('trNewMail').style.display = "none";
    			document.getElementById('tdNewMailHeader').className = "mailNotSelected";
    		break;
    	}
    	return true;
    }
    </script>
