GetElementByID nog working for DIVs in Firefox?

Jan Doggen · Jul 19, 2006

Hello,

The following code displays the name for all three elements in IE, but fails
for the1st and 3rd in Firefox.
What could be going on?
I tried SPAN instead of DIV doesn;t work either.
(What I finally want is to set style.invisibility for the text in that DIV)

TIA
Jan

<HTML>
<BODY onload="Init()">

<script type="text/javascript">
function Init()
{
if (document.all)
var msg = 'document.all OK'
else
var msg = 'document.all N/A';

if (document.getElementById)
alert(msg + '\ndocument.getElementById OK')
else
alert(msg + '\ndocument.getElementById N/A');

var divm = document.getElementById("menu");
if (divm)
msg = 'getelementbyid(menu): ' + divm.name
else
msg = 'getelementbyid(menu): N/A';

var ff = document.getElementById("varProfBevoegdheden");
if (ff)
msg = msg + '\ngetelementbyid(varprofbevoegdheden): ' + ff.name
else
msg = msg + '\ngetelementbyid(varprofbevoegdheden): N/A';

var divi = document.getElementById("bvtext");
if (divi)
msg = msg + '\ngetelementbyid(bvtext): ' + divi.name
else
msg = msg + '\ngetelementbyid(bvtext): N/A';

alert(msg);
}
</script>

<div id="menu" name="menu">
<table>
<tr><td>Zoeken 1</td></tr>
<tr><td>Zoeken 2</td></tr>
</table>
</div>

<table>
<tr>
<td>
<div id="bvtext" name="bvtext">Bevoegdheid:</div>
</td>
<td>
<select id="varProfBevoegdheden" name="varProfBevoegdheden" size="4">
<OPTION VALUE="1">Geen voorkeur\n.v.t.
<OPTION VALUE="2">1e graads
<OPTION VALUE="4">2e graads
</select>
</td>
</tr>
</table>

</BODY>

The first and third elements are DIV elements and DIV elements do not
have NAME attributes in HTML. Firefox is representing this truth by not
creating non-standard properties of these element for any NAME
attributes included in the mark-up for those elements (and any other for
which NAME attributes are not defined), while IE transfer just about any
attribute's value defined in the HTML onto a property of the
corresponding element.

(What I finally want is to set style.invisibility for the
text in that DIV)

You have successfully retrieved references to the elements using their
ID attributes so setting properties of their - style - objects should
not be a problem.
