Autofill Textbox from Dropdown values without page reload !! HELP !!

[shrike202]

This is what I want to do...

I have a user registration page and I'd like to pass the values of 3 drop down menus into a text box field on the same page.

When they finish the form and hit submit the value in the text box field is used to populate the user record and the text box data is discarded.

 

In addition, the user could override this by typing in the box or deleting some or all of the text generated by the drop down selections.

 

What I don't get is how to pass the values from the dropdown to the text field without a page reload.

I am a noooooooooooob and I'm sorry if this is obvious but I would really appreciate a push in the right direction. Thanks
