    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;
}

    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>
