This is an experimental technologyCheck the Browser compatibility table carefully before using this in production.

The WebGL2RenderingContext.getIndexedParameter() method of the WebGL 2 API returns indexed information about a given target.

Syntax

any gl.getIndexedParameter(target, index);

Parameters

target: A Glenum specifying the target for which to return information. Possible values:

gl.TRANSFORM_FEEDBACK_BUFFER_BINDING

Returns a WebGLBuffer.
gl.TRANSFORM_FEEDBACK_BUFFER_SIZE: Returns a GLsizeiptr.
gl.TRANSFORM_FEEDBACK_BUFFER_START: Returns a GLintptr.
gl.UNIFORM_BUFFER_BINDING: Returns a WebGLBuffer.
gl.UNIFORM_BUFFER_SIZE: Returns a GLsizeiptr.
gl.UNIFORM_BUFFER_START: Returns a GLintptr.

index: A GLuint specifying the index of the target that is queried.

Return value

Depends on the requested information (as specified with target).

Examples

var binding = gl.getIndexedParameter(gl.TRANSFORM_FEEDBACK_BUFFER_BINDING, 0);
