MDN’s new design is in Beta! A sneak peek: https://blog.mozilla.org/opendesign/mdns-new-design-beta/

webglcontextcreationerror

The webglcontextcreationerror event of the WebGL API is fired if the user agent is unable to create a WebGLRenderingContext context.

This event has a WebGLContextEvent.statusMessage property, which can contain a platform dependent string with more information about the failure.

Bubbles Yes
Cancelable Yes
Target objects HTMLCanvasElement
Interface WebGLContextEvent

Example

var canvas = document.getElementById('canvas');

canvas.addEventListener('webglcontextcreationerror', function(e) {
  console.log(e.statusMessage || 'Unknown error'); 
}, false);

var gl = canvas.getContext('webgl');
// logs statusMessage or "Unknown error" if unable to create WebGL context

Inheritance

The webglcontextcreationerror event implements the WebGLContextEvent interface, which inherits from Event. You can use the properties and methods defined on these interfaces.
