Use Address Autofill for Online Checkout (Javascript)

Additional Developer Resources

This example combines several Mapbox Search JS elements together to simulate an online checkout experience. It includes form filling from autofill, a visual reference Minimap, and an address confirmation step.

Fill out the form below. Try one of the following user flows, or experiment on your own.

Scenario 1: Search for Address and Autofill form

  1. Start typing an address into the address field
  2. Choose a suggested address
  3. Confirm the address' location on the minimap
  4. Click the Continue button
  5. Confirm the final address, or go back and change it

Scenario 2: Manually fill form and confirm address

  1. Manually enter an incomplete or inaccurate address into the form fields
  2. Click the Continue button
  3. If the address is not an exact match for a known address, the address confirmation dialog will open
  4. Choose whether to use the suggested address or to continue with the one you entered
  5. Confirm the final address, or go back and change it
