html - Check if parent element contains certain child element using jQuery

Question

<div id="example">
  <div id="test"></div>
</div>

<div id="another">Blah</div>

I want to set $('#another').hide() but only if #example contains a child element called#test, is this possible? It seems like it would be.

Answer 1

Use length

if ($('#example').find('#test').length) {
    // found!
}
