WebGLRenderingContext.validateProgram() - Web API | MDN

Baseline Widely available

WebGLRenderingContext.validateProgram() 是一种 WebGL API ，主要是用来验证 WebGLProgram。它在检查 WebGLProgram 程序是否链接成功的同时还会检查其是否能在当前的 WebGL 中使用。

void gl.validateProgram(program);

None.

var program = gl.createProgram();

// Attach pre-existing shaders
gl.attachShader(program, vertexShader);
gl.attachShader(program, fragmentShader);

gl.linkProgram(program);
gl.validateProgram(program);

if (!gl.getProgramParameter(program, gl.LINK_STATUS)) {
  var info = gl.getProgramInfoLog(program);
  throw "不能编译 WebGL 程序。\n\n" + info;
}

gl.useProgram(program);
