descendantOf

descendantOf(element, ancestor) -> Boolean 

Checks if element is a descendant of ancestor.

As Element.descendantOf internally applies $() to ancestor, it accepts indifferently an element or an element’s id as its second argument.

Examples


<div id="australopithecus">
  <div id="homo-herectus">
    <div id="homo-sapiens"></div>
  </div>
</div>

$('homo-sapiens').descendantOf('australopithecus');
// -> true

$('homo-herectus').descendantOf('homo-sapiens');
// -> false
