如果不加载，则替代WebGL

Question

I have some WebGL stuff in an iframe. On some web browsers or old computers, the iframe isn't loading. When this happens I'd like to load an image instead. Is it possible and if yes how to do it ?

Thanks

Wether or not WebGL is supported is probably best checked the same way you do in Javascript

WebGLRenderingContext gl = canvas.getContext("experimental-webgl")

if(!gl)
{
    $("#image").show()
}
