Highlighting part of the text in a text box

[Aria]

Hi all,

I've been struggling with this for days. How can I use javascript to
high light a part of the text in a textbox or a textarea?

OR

if the user highlights a part of the text in a textbox or a textarea,
how can I say which part of the text is highlighted? (ie: at what
character the highlight starts and at what character the highlight
ends).

thanks in advance.

function sel(o) {
if (o.selectionStart) {
return o.value.substring(o.selectionStart,o.selectionEnd) ;
} else {
return document.selection.createRange().duplicate().text;
}
}

....
<input type="text" onmouseup="alert(sel(this))" />

thanks. Is o.selectionStart and o.selectionEnd the code to use for
netscape?
