jQuery – Empty selector example
In jQuery, the “empty” selector is used to select all elements that have no children (including any text inside).
Examples
<div class="div-class1">
This is div-class1
</div>
<div class="div-class2" />
$(‘:empty’) – The “div-class2” is matched, while the “div-class1” is not.
