How to hide/show a div?

[Miguel Dias Moura]

Hello,

I have an image and a div named "content" in an ASP.Net / VB web page.

I need to create something like an on/off (visible/hidden).

1. When I click the image and the div is visible, the div becomes
hidden.
2. When I click the image and the div is hidden, the div becomes
visible.

So it's only one image controlling the div visibility.

How can I do this?

Thanks,
Miguel

Server side or client side?

On the server, it's easy:
myControl.Visible = true;
myOtherControl.Visible = false;

On the client, it's trickier, but doable:
<script>
// Always test EVERYTHING! Script errors suck.
if (document && document.getElementById)
{
var myControl = document.getElementById("myControl");
var myOtherControl = document.getElementById("myOtherControl");

if (myControl && myOtherControl)
{
myControl.style.visibility = "visible";
myControl.style.position = "relative";

myOtherControl.style.visibility = "hidden";
myOtherControl.style.position = "absolute";
}
}
</script>

Good luck!

Hi,

Thanks for the help.

What are the advantages and disadvantages or each approach?

Is server side code the best way?

Thanks,
Miguel

It depends, server side code will required a round trip back to the server,
slowing your user experience and adding load to the server but will always
work regardless of the client.

Client side will perform better, but you have the problem of testing to
ensure your client side script works on all browsers, and the knowledge that
it won't work at all if the user has scripting turned off.
