在本文中 WebGLRenderingContext.deleteProgram()

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.

WebGLRenderingContext.deleteProgram() 用于删除一个 WebGLProgram 对象。如果该WebGLProgram 对象已经被删除，该方法不会产生任何作用

语法 
void gl.deleteProgram(program);
参数
program

需要被删除的 WebGLProgram 对象

返回值

None.

示例 删除一个程序

js

var canvas = document.getElementById("canvas");
var gl = canvas.getContext("webgl");
var program = gl.createProgram();

// ...

gl.deleteProgram(program);
