Trying to get value of a radio button in JavaScript

[Mufasa]

I have a couple of radio buttons that make various things appear/disappear
on the screen through JavaScript. All works great. Problem is I'll click a
radio button, something will appear, I reload the page for other reasons and
the item disappears. The reason it disappears is I have to set the state
initially to invisible so it doesn't show up initially.

The radio buttons are html radio buttons not aspx radio buttons so I can
have the javascript react to it.

I'm also using master pages just to complicate life.

So how do I check the value of the radio button in javascript so I can then
make the item appear depending on which button was selected.

TIA - Jeff.

Hi Jeff,

You can use Request.Form("checkboxname") in ASP.net to do some logic
to change the initial visibility on postback.

I think you can use something like this

document.getElementById('ID').checked = true;

where ID is the id of your radio-button
