Cooperative Gesture Handling

Spark icon

Page Summary

This sample demonstrates how to implement "cooperative" gesture handling on Google Maps for mobile devices.
Cooperative gesture handling requires users to use one finger to scroll the webpage and two fingers to pan the map.
The sample utilizes the gestureHandling option set to "cooperative" within the Map instantiation.
The provided code snippets showcase the implementation in TypeScript, JavaScript, CSS, and HTML.
Users can try the sample live using provided links to JSFiddle and Google Cloud Shell, or clone and run it locally.

This example uses the cooperative value for the gestureHandling option to control the panning and scrolling behavior of a map when viewed on a mobile device.

Read the documentation.

TypeScript

/**
 * This sample sets the gesture handling mode to 'cooperative',
 * which means that on a mobile device, the user must swipe with one
 * finger to scroll the page and two fingers to pan the map.
 */
functioninitMap():void{
constcenter={lat:-25.363,lng:131.044};
constzoom=4;
newgoogle.maps.Map(document.getElementById("map")!,{

JavaScript

/**

CSS

/* 
 * Always set the map height explicitly to define the size of the div element
 * that contains the map.
