A way to "bulk clear existing data fields" when cloning a page?

A way to "bulk clear existing data fields" when cloning a page?

Is there an implementation option where I can easily clear the data in a page when the user presses on the "Clone" button on a page? My current thought is to implement a Client Script that gets triggered by onLoad event for Clone Page and call 
  1. ZDK.Page.getField(<field API name>).setValue("");
But I have many fields in this record layout, so does anyone have a suggestion for a less tedious way to clear data of all the fields in a record when a record is being cloned?
