Place Autocomplete Data Predictions | Maps JavaScript API

Stay organized with collections Save and categorize content based on your preferences.

This example demonstrates calling fetchAutocompleteSuggestions() for the input "Tadi", then calling toPlace() on the first prediction result, followed by a call to fetchFields() to get place details.

Read the documentation.
