WebGLRenderingContext.getShaderInfoLog returns the information log for the specified WebGLShader object. It contains warnings, debugging and compile information.

句法

gl.getShaderInfoLog(shader);
					

参数

shader

WebGLShader to query.

返回值

A DOMString that contains diagnostic messages, warning messages, and other information about the last compile operation. When a WebGLShader object is initially created, its information log will be a string of length 0.

范例

Checking compilation messages

/* load shader source code. */
gl.shaderSource(shader, shaderCode);
/* compile shader source code. */
gl.compileShader(shader);
var message = gl.getShaderInfoLog(shader);
if (message.length > 0) {
  /* message may be an error or a warning */
  throw message;
}
