Confirmation when user leaving the form

[Phu Hiep DUONG]

Hello,

How can we implement this feature in Polymer?

(example from github wiki page editing)

I suppose we have an application based on Polymer Starter Kit (so with page.js as router engine)

- this application uses a product-editor element which contains a textbox + save button. 

- User is editing a product at the route localhost/#!/product/127/edit

- and "accidently" click on the Back button or other links on the page

I'd like to display the above confirmation dialog: "Are you sure you want to leave this page?"

How can we do this?

Thank you
