Javascript code that automatically fills in the address in all places needed on the page after just once entering it and selecting the check box.
Introduction:
I ran across this code when working on a registration product site. The goal is to save the user’s time by not having them fill in the same address over and over, if the address for there billing is the same as the mailing address.

The sample source code has a slight error. Copy from the source code of the example page instead and it'll work fine!
to_el = f['bill' fld_name[i ]]; // on this page
to_el = f['bill' + fld_name[i++]]; // on working example page

You wrote productivaty
Also, make sure that ‘bill’ (or whatever you change it to) is the prefix to the names of your 2nd set of boxes.
to_el = f['bill' fld_name[i ]];
if first set of boxes are named ‘city’ and ’state’
so 2nd set would be called ‘billcity’ and ‘billstate’
also, make sure you put in your input names in here where ‘city’ and ’state’ are:
var fld_name = new Array(‘city’ , ’state’);
thanks for the code so i didnt have to write it myself!
