Selecting Two Values in a Multiple List Box

[lee2k]

hi,

in a form named "f1" i have a multiple list box named "m1" with ten values such as "one","two","three",...."ten". if i click a button then "three","five" and, "Seven" should be selected.
i want to write such a function in javascript.

hope anyone will help me in this regard..

okay, this is how it works:

you have a form with a select box in it:

<form name=f1>
<select size=7 name=sel multiple>
<option>#1
<option>#2
<option>#3
<option>#4
<option>#5
<option>#6
<option>#7
<option>#8
</select>
</form>

now, think of the select box not only as an html element, but as a js array also.

you can refrence each option by using:

document.f1.sel.options[x]

(where x is some value)

then, each option has its own set of read-write variables:
value, text, selected, and probably some more

so, if you wanted to select option #6, use

document.f1.sel.options[5].selected=true;

that should help, I hope I didnt bore you with a long explanaition theEclipse
