show/hide Layers modification

Hi all,

Since I recently modifies the MM_showHideLayers() function and it worked just
fine, I want to share it so people with the same problem as mine could rely on
it.

Enough said, the problem I encountered is that despite the "visible/hidden"
properties on the Layers, they still [i]ocuppy[/i] space on the page. BE if I
tried to put some resultSet into a table and hidding in from the user until a
mouseOver or mouseClick behavior, the <td> were populated and the table
displayed in a way that I didn?t want.

I found out that modifiying the function with the "inline/none" properties for
the layers the trick was done and the tables were displayed as if no data
populated the <td>'s.

Here is the code:

function DM_displayLayers() { //v1.0
var i,p,v,obj,args=DM_displayLayers.arguments;
for (i=0; i<(args.length-2); i+=3) if ((obj=MM_findObj(args[i]))!=null) {
v=args[i+2];
if (obj.style) { obj=obj.style; v=(v=='on')?'inline':(v='off')?'none':v; }
obj.display=v; }
}

It works very similar to the MM_showhideLayer() function but accepts the "on"
/ "off" parameters instead of "show" /"hide". And requires MM_findObj.

Also found that the two fuctions can be applied to almost any object in an
html.

Greetings,

Jerry

Shouldn't it be display:block and display:none?

depends on if your target element is a block or inline element, eg img
->> display:none p --> display:block

In the case of the modifications posted, the only choices are inline and
none, meaning that it can only 'properly' be applied to inline elements -
that was my point.

To do it for divisions only, the 'inline' would have to be changed to
'block'.

Hi, I am a newbie to all this and would like to know more about the script you
taking about?

It seems to do, what I am trying to achieve? Could you point me in the
direction of a tutorial which explains what all the code does?

Thanks
