Some HTML and Javascript Help

[AustinJ]

This is hard to describe, but I am going to try.

Three Selects:

Option 1
Option 2



Option 3
Option 4

Events I want to occur:

When 'select_1' changes the currently select option, I want the first option of 'select_3' to change to the id and label of the currently selected option of 'select_1'.

When 'select_2' changes the currently select option, I want the second option of 'select_3' to change to the id and label of the currently selected option of 'select_2'.

This will give you a push in the right direction:

$(document).ready(function() {

$('#select_1').change(function() {

   alert('select_1 has changed');

});

});

You'll need jQuery, it makes all the Javascript code as small as it gets, like shown above.

That code will show an alert when you change an option.

Replace the alert with some 'document.GetElementById("select_3")' code, and you're done. :)

If you aren't familiar with the that function, read this:

Or this:

You can do lot's of stuff with it.

Welcome to Javascript. ;)
