can't get height of table in ie5

[pigsie]

Hi

I'm trying to get the size of a table. I have a table called grid (id="grid") but ...

getElementById('grid').getAttribute('height');

returns blank. I can get the width but not the height and I'm wondering if its because the table width is specified but not the height. Unfortunately due to a number of reasons this has to work/is not working on ie5. Does anyone know if this is a bug?

Thanks

Hello pigsie,

If the height and/or width are not explicitly set as table tag's attributes, getAttribute("height") or same "width" would return empty. In that case, I would suggest you retieve instead using properties clientHeight and clientWidth: (alert say)
[tt]
alert(getElementById('grid').clientHeight);
[/tt]
If there is border setting, say border=n (n some number), total height would be adding twice the border setting:
[tt]
totalHeight = clientHeight + 2 * bordersetting [green](this is not code)[/green]
[/tt]

Correction:

I meant sure
[tt] [blue]document.[/blue]getElementById('grid').clientHeight
[/tt]

I guessed as much however the above code returns blank for the height in ie5, in the end I had to use a combination of different methods:

alert(document.getElementById('grid').getAttribute('width'));
alert(window.document.all.grid.clientHeight);

Which is the only combination which seemed to work for both height and width in ie5 and ie6.

Thanks

alert(document.getElementById('grid').offsetHeight)
alert(document.getElementById('grid').offsetWidth)

vbkris,

Thanks for the suggestions, unfortunately I just tested it in ie5 and

alert(document.getElementById('grid').offsetHeight)
alert(document.getElementById('grid').offsetWidth)

will return 0 for the height even if a height has been specified. It does however work in ie6.

Thanks
