I need some help because I want to use some jquery (and css probably) on some custom fields on post edit screen. What I need exactly is to make , and . magically apear when user types a number: types 100, jquery makes it 1,00 and so on. The custom field I created using the plugin Types and it's named wpcf-imovel-preco. I have no clue about using jquery to manipulate elements on backend :(, that alone would be great help, so i know where to start from!
