flashing tbale border in FileFox

[Lazer]

Hi.
I tried to get a flashing table bordr, it worked OK in IE 6 but NOT if FF.
I found the the problem is:
FF can WRITE getElementById but it CAN NOT READ IT
so I found an "Elegant" way to bypass it by creating a dummy color variable: col
the table is:
<table border="0" id="table" style="border: 4px blue solid;">
.....
</table>

<script language="javascript">
var col = 'blue'
function flasher() {
if(col == 'blue') {
document.getElementById('table').style.borderColor = 'red'
col = 'red'
} else {
document.getElementById('table').style.borderColor = 'blue'
col = 'blue'
}
setTimeout("flasher()" , 1000)
}
</script>
<script language="javascript">flasher();</script>

It works in both IE6 and FF 3.

Firstly, that's got nothing to do with FF's use of getElementById, it's because first time FF calls that function the style is not stored on the element, it's in a style attribute, which for some reason it treats differently. Where you have:

[code]col = blue;[/col]

Do:

document.getElementById('table').style.borderColor = 'blue'

Then your original IE code should work on FF too. Or, better yet, do:

var elStyle = document.getElementById('table').style;
elStyle.borderColor = 'blue';

Saves a lot of time in subsequent uses if you use that variable instead.
