Change contents of textareawhen pressing a button.

Say I have three buttons and a textarea, when I press a button, I want all the text in the text area replaced by a preset JavaScript variable (so if the variable = "hello", all the text in the textarea will be replaced by "hello" on buton press.) If possible, I would like a confirmation box to appear first (e.g: "Are you sure"? - if you press yes it replaces the ext, if you press no, it doesn't).

I need this done for three different buttons.

My current HTML:

<textarea name="code" class="mainscript" cols="100" rows="50">
<input name="butt1" type="button" value="Button1"><input name="butt2" type="button" value="Button1"><input name="butt3" type="button" value="Button1">

Code (markup):

Cheers,

add id="code" to the textarea:
<textarea name="code" id="code" class="mainscript" cols="100" rows="50">

<input name="butt1" type="button" value="Button1" onclick="document.getElementById('code').value = 'hello';">


you should be able to change the literal "hello" to a variable.

 

Thanks you alot
