Example of .addBack() in jQuery
February 17, 2013
.addBack() adds DOM element in the stack. In the current set of element .addBack() adds the previous element. Now take the example. We have three p element. Only one p has class attribute. What we are targetting is give a back ground color to all the three p with .addBack().
<p class="a">A</p> <p>B</p> <p>C</p>
$('p.a').nextAll().css('background-color', 'yellow')
$('p.a').nextAll().addBack().css('background-color', 'yellow')
