Function: labelledBy(domElementOrCSSSelector, target-domElementOrCSSSelector)

Description: Specifies that the accessible name for an element is to be set using one or more other elements.

Returns: Original Object, or $A object if chained.

Note: The labelledBy() function will automatically set the accessible name for an element, even if the target elements do not include an id. It will automatically manage the aria-labelledby attribute accordingly.

Example:

$A.labelledBy(domElement, domElementLabel);

$A.labelledBy("#listbox-id", ".label-country, .label-state");

// Or the same using chaining

$A(domElement).labelledBy(domElementLabel);

$A("#listbox-id").labelledBy(".label-country, .label-state");
