This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes.

The CanvasRenderingContext2D method clearHitRegions() removes all hit regions from the canvas.


void ctx.clearHitRegions();


Using the clearHitRegions method

This example demonstrates the clearHitRegions() method.


<canvas id="canvas"></canvas>


const canvas = document.getElementById('canvas');
const ctx = canvas.getContext('2d');

// Set some hit regions
ctx.addHitRegion({id: 'eyes'});
ctx.addHitRegion({id: 'nose'});
ctx.addHitRegion({id: 'mouth'});

// Remove them altogether from the canvas


Canvas hit regions have been removed from the WHATWG Living Standard, although discussions about future standardization are ongoing. See for more information.
