render()

ILIAS\UI\Implementation\DefaultRenderer::render	(		$component,

Render given component.If an array of components is passed, this method returns a concatenated output of each rendered component, in the same order as given in the array

Parameters

?Renderer	$root of renderers in the chain to be used for rendering sub components.

Returns

string

Same as render, except that this version also returns any javascript code bound to the on load event, wrapped in a script tag.All javascript code stored for rendering will be removed after this output so it will not be rendered twice if render async is called multiple times.

Parameters

Component|Component[]	$component
?Renderer	$root of renderers in the chain to be used for rendering sub components.
