Hi,

here is a simplistic javascript example to populate a textbox from vars in the script.
I am not sure whether this is what you wanted...

Code:
<script>
var texts = Array('this is first text<br>multiline', 'another text');
function showtext(n)
{       document.forms.form1.ta.innerHTML = texts[n];
}
</script>
<form name=form1>
<textarea name=ta rows=5 cols=50></textarea><br>
<input type=button value=text1 onclick='showtext(0)'>
<input type=button value=text2 onclick='showtext(1)'>
</form>
