HTML DOM TouchEvent metaKey Property

The HTML DOM TouchEvent metaKey property returns a Boolean value corresponding to the state if meta was pressed when a touch event was fired.

Following is the syntax −

Returning boolean value - true/false

touchEvent.metaKey

Here, “booleanValue” can be the following −

booleanValue	Details
true	It defines that meta key waspressed when touch event occurred
false	It defines that meta key wasnot pressed when touch event occurred

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 metaKey property −
