WebGLRenderingContext.getError()

The WebGLRenderingContext.getError() method of the WebGL API returns error information.

Syntax

GLenum gl.getError();

Parameters

None.

Return value

Constant Description
gl.NO_ERROR No error has been recorded. The value of this constant is 0.
gl.INVALID_ENUM An unacceptable value has been specified for an enumerated argument. The command is ignored and the error flag is set.
gl.INVALID_VALUE A numeric argument is out of range. The command is ignored and the error flag is set.
gl.INVALID_OPERATION The specified command is not allowed for the current state. The command is ignored and the error flag is set.
gl.INVALID_FRAMEBUFFER_OPERATION The currently bound framebuffer is not framebuffer complete when trying to render to or to read from it.
gl.OUT_OF_MEMORY Not enough memory is left to execute the command.
gl.CONTEXT_LOST_WEBGL If the WebGL context is lost, this error is returned on the first call to getError. Afterwards and until the context has been restored, it returns gl.NO_ERROR.

Examples

gl.getError(); // gl.NO_ERROR (0)

gl.enable(gl.FOOBAR);
gl.getError(); // gl.INVALID_ENUM;
