WEBGL_lose_context.loseContext()
The WEBGL_lose_context.loseContext() method is part of the WebGL API and allows you to simulate losing
the context of a WebGLRenderingContext context.
It triggers the steps described in the WebGL specification for handling context lost.
The context will remain lost until WEBGL_lose_context.restoreContext() is
called.
Syntax
loseContext()
Parameters
None.
Return value
None (undefined).
Examples
With this method, you can simulate the
webglcontextlost
event:
const canvas = document.getElementById('canvas');
const gl = canvas.getContext('webgl');
canvas.addEventListener('webglcontextlost', (e) => {
console.log(e);
}, false);
gl.getExtension('WEBGL_lose_context').loseContext();
// WebGLContextEvent event with type "webglcontextlost" is logged.
