I have a select list form field on my page, and I would like it to control what is displayed in a text box next to it. In a simple form, it would be something like a list of users, and then upon selection of a user in the dropdown, their email would display in the text box (or div , etc) next to it.
The select list is being generated from a DB table already, and each option has a user_id as the value (ex. 1, 2, 3,e etc..). I also build an array of user data (in PHP) which includes the user_id and user_email that I need to somehow pass on to JS.
I am assuming I need to build some sort of JS array code out of my array data in order for my select list to be able to display a certain array value? What would that look like?
If I had a select list created, and a JS array, how do I link the two together to alter the value of the email textbox upon onchange?
