javascript - component.query versus component.getcomponent in performance -
is component.query() faster component.getcomponent() ?
what pros , cons of using component.query ?
while ext.componentquery queries underlying components (you may define traversing start second param after query string) allow query various set of params, attributes, pseudo classes, functions, etc. full reference , result in set (array) compinstance.getcomponent('itemid') queries direct childs of calling component itemid property , return 1 reference or null. note itemid need unique it's siblings.
so yes getcomponent() bit faster.
i don't think there huge pros , cons. getcomponent() cannot used because may not looking in level. take menu groups the buttons, getcomponent() find group not within it. don't care it.
