count certain array items 1

[project3]

What I have is a form with select box named in array
name=s_active[]

what I want to do is prevent the form from being submitted if the array has more than 3 values=yes

I know how to work with arrays but am unsure how to count only ones with a certain value.

Thanks in advance!!

Do you mean that you want to check to see how many options in a select are selected?

I have got it almost figured out i can do it with an array i put in the code but Im having trouble pulling an array out of the input boxes in the html

I tried
var arr = document.theform.s_active[].value;

but that doesn't work how do i pull the array values in?

You can't use square brackets like that in Javascript. Try accessing it through an associative array like this:

document.forms['theform'].elements['s_active[]'].value;
