Selections Chosen For a Multi Select Combo Box

Copy linkTweet thisAlerts:

Hi,
If I have a multi select combo box, that is with the ability to chose more than one option how in Javascript can I get a handle on the values selected by the user?

If the user chose the first three options from the following combo box I know that:

document.form1.ProductGroup.options[document.form1.ProductGroup.selectedIndex].value

would return 11, but how can I get a handle on what was really selected eg(11,4, and 9)?

Does anyone know?

<select MULTIPLE size=”3″ name=”ProductGroup” class=”TextFields” onchange=”” disabled>
<option value=”11″>Esignal</option>
<option value=”4″>FoxTrader </option>
<option value=”9″>General</option>
<option value=”6″>Hubb</option>
<option value=”10″>Optionetics</option>
<option value=”12″>Publications</option>
<option value=”7″>Safety in the Market</option>
<option value=”5″>ShareAnalyser</option>
<option value=”8″>Sherpa</option>
</select>

Thanks
Andrew
