WebGLContextEvent.statusMessage

The read-only WebGLContextEvent.statusMessage property contains additional event status information, or is an empty string if no additional information is available.

The statusMessage property can contain a platform dependent string with details of an event. This can occur, for example, if the webglcontextcreationerror event is fired.

var canvas = document.getElementById('canvas');
var gl = canvas.getContext('webgl');

canvas.addEventListener('webglcontextcreationerror', function(e) {
  console.log('WebGL context creation failed:' +
              e.statusMessage || 'Unknown error');
}, false);
