i'm having a form in which a text field has a js function which lists the name of the customer by searching the letters typed in the field.. (like the one on gmail mail to column)

The js funtion is working well and there's no problem until i activated the store data options in the browser.

Once i use the forms the data entered before in the form fields are stored by the browser and they are gets listed over the div that is listed by the invoked js function. i want to restrict the browser not to list the stored form data for that field or even restrict the storage of data for that particular field..

Can anyone help on this?
