// Script starts here.
// View a sample form demo.

/*

This script uses the saveForm() function to save a form's entries for 60 days.
The autoFill() function can enter the saved values on future visits.
Note: These functions apply only to text inputs and single-choice selectors.

Run the save function with the form object to save as its argument.
e.g. onSubmit="saveForm(this);" would save the current form's data at submission.
This function can also save only a form slice.
e.g. "saveForm(document.form_name, 5, 31);" would save the 6th to 32nd fields.

Run autoFill() with the form object to fill-in as its argument.
e.g. onLoad="autoFill(document.form_name);" would fill form form_name.

Important! This entire script must be pasted between script tags in the document head.
