You do not want to use a hidden field.
You need to use a regular text box with style="visibility:hidden"
when you want to show it
document.getElementById("ElementName").visibility="visible";

You can't really change a field type. If you just need to display text in a field when a button is pressed, you can use the onClick event to place the text into the text field.

In the code, you'll notice I had to replace onClick with onKlick to post it to the list. Change it back to onClick to run it.

Eric, it's six of one or half a dozen of the other. Use JavaScript to change the visibility, or use JavaScript to add the value to a previously empty text box. It's exactly the same amount of code give or take a few characters.

--OR--

Tom: That's not the same thing at all.

If someone used your method, then when the form is submitted, any 'hidden' values are sent as empty string, when it in fact they should contain some value. We want to hide the value from a user, not null it.

The requirement of the original poster is fuzzy, and its unclear if a value should be submitted for 'hidden' fields or not. But I thought i'd point out that Erics method and your method do NOT produce the same results server-side.

You are right Mike. I didn't think about if he needed the value in the hidden element. I assumed it was something like an online practice test where the button was "check you answer".
That's what I get for assuming
