Examples
With the help of the WEBGL_lose_context
extension, you can simulate the webglcontextlost
and webglcontextrestored
events:
var canvas = document.getElementById('canvas');
var gl = canvas.getContext('webgl');
canvas.addEventListener('webglcontextlost', function(e) {
console.log(e);
}, false);
gl.getExtension('WEBGL_lose_context').loseContext();
// WebGLContextEvent event with type "webglcontextlost" is logged.
