How to copy value from one field to another in a Apex Form

Question

Hello guys,
There are 2 addresses one is shipping and other is billing. I do not want the customer to re-enter all the details if it is the same address. So based upon an action, it should take the live values from one address field and populate the other address field. I know in JS you can do it, but how to implement that in Apex?
I guess using Dynamic Actions to achieve this in Version 4 but do not know how. Read quite some info but no luck.
Thanks in advance!

Hi,
I have assumed that you have your shipping address at the top of the page, and then further down the page you have your billing address that you want to enable the users to copy (if this is in reverese, you will need to switch the js variables in the code following).
I would create a Select List item above the 'Billing Address' details, called PX_SAME_ADDRESSThis select list would be static, with the options Null.
I also assume you would have pairs of address page items such as:
PX_SHIPPING_ADDRESS_L1
PX_BILLING_ADDRESS_L1
PX_SHIPPING_ADDRESS_L2
PX_BILLING_ADDRESS_L2
PX_SHIPPING_POST_CODE
PX_BILLING_POST_CODEThen copy the following code into the HTML Header of the page definition:
<script language="JavaScript" type="text/javascript">
function copyAddress()
   if( $x('PX_SAME_ADDRESS').value == 'YES')
     $x('PX_BILLING_ADDRESS_L1').value = $x('PX_SHIPPING_ADDRESS_L1').value;
     $x('PX_BILLING_ADDRESS_L2').value = $x('PX_SHIPPING_ADDRESS_L2').value;
     $x('PX_BILLING_POST_CODE').value = $x('PX_SHIPPING_POST_CODE').value;
   else //Clear Address Fields
     $x('PX_BILLING_ADDRESS_L1').value = " ";
     $x('PX_BILLING_ADDRESS_L2').value = " ";
     $x('PX_BILLING_POST_CODE').value = " ";
</script>Then, in your PX_SAME_ADDRESS item, copy the code below into the Element > HTML Form Element Attributes field.
onChange="copyAddress();"Hopefully this works for you too, and should give you some basis to play around with.
