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
