Html Code: Rescue text and textarea values

It is a useful script for developers and in the online filling forms.
Sometimes during filling a online form, you may loss the entered data in the text box or text area ( due to error or connection lost) and you must fill those again.
But by this script, the entered data will be saved and by returning to page, the last entered data will be shown.
