Javascript Forms Select Selectedindex

Question

Having problems with the following - Not working as expected, getting JS doc errors as well.

JSFiddle Nota Worka.

Answer 1

try this fiddle: http://jsfiddle.net/maniator/egjF4/6/

and change the if line to:

if (document.forms['myform'].selectbox1.selectedIndex == 2)

you need the == to check values

UPDATE

Based on your comments below here is the jQuery for the same thing:

$(function(){
    $('#selectbox1').change(function(){
        if(this.selectedIndex == 2){
            $('#input1, #input2, #asterisk').css('visibility', 'visible');
            $('#input2').addClass('required');
        }
        else {
            $('input, #asterisk').css('visibility', 'hidden');
            $('#input2').removeClass('required');
        }
    })
})
