Chrome (Blink):

Code review/patch (Blink):

Firefox (Gecko):

https://bugzilla.mozilla.org/show_bug.cgi?id=979692


Please note the following code sample may be outdated. Will check back in a few weeks to see if Blink and Gecko have converged and have an example using a DOM element.


Code sample (from Firefox):

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

var ctx = input.getContext("2d");
ctx.beginPath();
ctx.rect(20, 20, 100, 75);
ctx.fill();
ctx.addHitRegion({id: "a"});


var regionId = "";
input.addEventListener('mousedown', function(evt){
 regionId = evt.region;
});
