multiple select boxes

[cajchris]

when I am using a multiple select box it is workin ok for a single selection, but not for many selections.

Here is my code for it:

<select name="searchedDirectoryNames" id="selectedDirectories" size = "2" class="normalSelect" multiple>

<option value="About Us">About Us</option>
<option value="News">News</option>
<option value="Registrants">Registrants</option>

</select>

when i select About US, News, and Registrants in that order using the ctrl key it is being interpreted as only About Us being Selected.

even more strangely when i select News, Registrants and then About Us, it is still being interpreted as About Us. so it seems it is taking the top one only in the multiple select case.

i was told on the html forum that i required javascript. would any1 be able to post some example script that would get these multiple values. I take it the values would be in the form of some comma seperated list.

the variable searchDirectoryNames needs to contain the values selected as this is then interpreted by my search engine to determine which directories to search on

any ideas?

thanks

If you want to pick up on all values server-side (i.e. AFTER the form has been submitted), then you would use whatever server-side language you normally use. No client-side JavaScript is required.

If you want to do somethiing with the values client-side, then you'd need to explain what you want to do with them (or how you want them) before help can be given. Saying "I take it the values would be in the form of some comma seperated list." implies you don't actually know yourself how you want the values... so how about YOU tell US how you want them?

Hope this helps,

I do not have different opinion. But, if you just want to see client-side what server-side would see before submitting, it is very easy.

var s="";
var elem=document.getElementById("selectedDirectories");
for (var i=0;i<elem.length;i++) {
s+=(s=="")?elem.options.value:","+elem.options.value;
}
//alert(s); //to display

If it appears in some kind of handler, elem may be simplified depending on the concrete.
