Are you sure this is an APEX question?
If LOGRADOURO, BAIRRO, etc are APEX items it may be best to use the built in $v to get their value. $v takes into account the different type of APEX items. The counter part is $s to set values
var b = $v("BAIRRO");
Now... because I don't see a page number on your items... are these Application Items? If so, what you're doing will not work like this because Application Items are not part of the client side page (the page HTML) only on session state.
Perhaps we need some more clarifications...
thank you for your help
I have 1 imput item
and 4 itens to get the returned values from url :
like this example
you can type 13280000 and see the returned values
I am trying this using apex.
I fixed the problem,
the correct way to call this jvascript is:
onblur="atualizacep(this.value)" ( on P1_CEP )
and now the itens are populated automatic after P1_CEP is entered.
