HTML DOM TouchEvent touches Property

HTML Web Development Front End Technology

The HTML DOM TouchEvent touches property returns a TouchList object corresponding to a list of all contact points triggered on a touch surface.

NOTE: If a touch is triggered on the specified node or any of its child nodes then the following touches will count even if they are not triggered on the same node.

Following is the syntax −

Returning TouchList object

event.touches

Note: We ran Touch event examples on Online HTML Editors accessed on Mobile or systems with touch access. This is done so that we can perform touch operations like touch the screen for 2 seconds.

Let us see an example of TouchEvent touches property −
