How can we know if the removeClass operation is success or Failed ??

<!DOCTYPE html>
<html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
  $("button").click(function(){
  var value =   $("p").removeClass("intro");

  });
});
</script>
<style>
.intro
{
font-size:120%;
color:red;
}
</style>
</head>
<body>

<h1>This is a heading</h1>
<p class="intro">This is a paragraph.</p>
<p class="intro">This is another paragraph.</p>

<button>Remove the "intro" class from all p elements</button>

</body>
</html>

You can verify whether the node still has the class after you've performed .removeClass() on it with the .hasClass() function:

if ($('p').hasClass('intro')) {
   ...
}

You can use .hasClass() to verify that:

$("p").hasClass("intro")
