Expand/Collapse DIVS

[James Hurrell]

Hi,

I'm using the following javascript function to expand and collapse portions
of text in a web page (targeted at IE5.5 and above):

function doExpand(paraNu m,arrowNum) {
if (paraNum.style. display=="none" ) {
paraNum.style.d isplay="";
arrowNum.src="c ollapse.gif";
}
else {
paraNum.style.d isplay="none";
arrowNum.src="e xpand.gif";
}
}

Implemented as follows:

<p><a href="JavaScrip t:doExpand(exp1 ,ar1)"><img src="expand.gif " id="ar1"
border="0" width="9" height="9"></a>
Title Text</p>
<div id="exp1" style="display: none" onclick="doExpa nd(exp1,ar1)">
<p>Drop down text here</p>
</div>

And repeated when required in the same page after changing the paraNum and
arrowNum parameters.

Does anyone know how I could adapt the script to enable more than one set of
DIVs to be expanded at the same time... i.e.: with a link that says "Show
All" and when clicked, all collapsed text on the page is then exapnded...?

Thanks in advance for any clues...

function doExpandAll( objImage ) {
var boolExpandAll = (objImage.src == 'expand.gif'); // Sets boolean
to true when expand image is clicked
for ( var intArg = 1; intArg < arguments.lengt h; intArg++ ) { // Loop
through all the arguments (ignoring first one, which is the image)
var objDiv = arguments[intArg]; // Create a reference to each
div object in turn
objDiv.style.di splay = (boolExpandAll) ? 'block' : 'none'; // If
expanding set to visible, else set to hidden
}
objImage.src = (boolExpandAll) ? 'collapse.gif' : 'expand.gif'; // If
expanding set to collapse-image, else set to expand-image
}

<p><a href="JavaScrip t:doExpand(ar1, exp1,exp2,exp3) "><img
src="expand.gif " id="ar1" border="0" width="9" height="9"></a> Title
Text</p>
<div id="exp1" style="display: none">
<p>Drop down text here</p>
</div>
<div id="exp2" style="display: none">
<p>Drop down text here</p>
</div>
<div id="exp3" style="display: none">
<p>Drop down text here</p>
</div>
