Hi,

I'm doing a project which should turn on Netscape 6 and Internet
Explorer 5.

My problem is:

I have different <div> elements and some of them should be hidden
onloading. For example:

<div id="1"> blablabla </div>
<div id="2" style="visibility:hidden"> blablabla </div>
<div id="3"> blablabla </div>
...

When my page is loaded, div id=2 is hidden. Therefore there is a hole
between div 1 and 3.
I would like to move up div id=3.
Thus I need height of div id=2 in order to assign height of div id=3 to
this value.

I don't want to calculate all the different heights (<div>).

I have tried among others this code (onloading and after loading with a
button):

var div = document.getElementsByTagName("div");
alert("Value of height for div[0]:  "+ div[0].getAttribute("height"));

There is no value on the alert window.

This let me suppose that the browser (IE and NN), after calculating the
best position for every element, don't assign the
value of attributes (that are not present in the html file). But I am
not sure.

Does somebody have an answer or alternative to my problem ?

Many thanks.

Véro

use "display:none" instead of "visibility:hidden".

sure. You haven't set an attribute "height" in the DIV tag, have you?
There are ways to get the computed size of elements, but I guess you
don't need them anymore... ;-)

wo.

BTW: Your choice of newsgroups was a bit strange. What about
comp.lang.javascript next time?
