JavaScript to get and update the 'value' of a text field?

[Toni Howlett]

<input type="text" name="orderNum" readonly="readonly" value="1" size="1" />

I plan to have multiple instances of the code above, and next to each, a button that says up, and another that says down. My goal is to have it when these are clicked, it will change the order in an array I have, but I need the value of the textfield to change as well so the user knows what order they are in.

With that said, all I need to know is that is there a simple way to get it and change it?

Give the element an id, then:

document.getElementById('whatever').value = 213;

You can get the reference other ways, but getting it by id is the least fragile and surest way.

Awesome, thanks!
Simple and just what I needed.
