I have a form with 15 Measurement input fields (text) plus a single dropdown Measurement unit (choice) containing measurement units (mm, cm, dm, m etc).
The user first selects the desired Measurement unit value, then inputs a measurement result in a Measurement field. On changing focus to the next field, the currently selected value in the Measurement unit field should be appended to the first field's contents.
How can this be achieved using Javascript?
