I want to change the value of a field when another field is updated.
Specifically, I want my e mail field to get it's data from the username,
the domain always being the same, so username is say johndoe, e mail
address will be joh...@wherever.com
my fields look like this:
<p><h3><label class="field" for="username">Username:</label></h3>
<%= f.text_field :username, :style => "width: 250px" %></p>
<p><h3><label class="field" for="email">Email Address:</label></h3>
<%= f.text_field :email, :style => "width: 250px" %></p>
Very much a beginner with JavaScript incidentally so be gentle
Do you really need to do this with Javascript?
As someone else has said, if the domain is always the same then you only really need to ask for the username. If you want to store the full email address in your database you could add it on server-side in your ruby code (if you're using Rails then as a before_save callback on the model)
Help is very much appreciated.
