Menu
I have an HTML table containing a few rows (this is built dynamically). All <tr>s have one <td> inside.
If one <td> doesn’t have HTML content inside, I would like it to be invisible.
How can this be done? (Not that the HTML inside is rendered dynamically and I do not want to use display:none or any other property on the <td> or <tr>).
Code sample:
<html>
<body bgcolor="#E6E6FA">
<table cellSpacing="0" cellPadding="0">
<tr>
<td>one cell</td>
</tr>
<tr>
<td bgcolor="#FF0000"></td>
</tr>
<tr>
<td>two cell</td>
</tr>
</table>
</body>
</html>
In Firefox the empty TD is invisible. However, in IE the TD takes up 1 pixel in height:
Looking with DOM Inspector I see that it takes 1 pixel:
How can I set the TD not to be visible? Any scripts I can execute inside the TD?

You can use the CSS pseudo selector :empty:
#myDynamicTable td:empty
{
display: none;
}

And if you want to support IE<9:
var ieVer = getInternetExplorerVersion();
if (ieVer != -1 && ieVer < 9.0) {
// for IE<9 support
var dynamicTable = document.getElementById("myDynamicTable");
var TDs = dynamicTable.getElementsByTagName("td");
for (var i = 0; i < TDs.length; i++) {
if (TDs[i].innerHTML == "") {
TDs[i].style.display = "none";
}
}
}

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;
}
