Working with hasClass() attribute in jQuery?

.hasClass() attribute determines whether class is assigned to any particular control or not.It returns true if any class is applied otherwise returns false.
For Example:-

<div id = "div_employee" class="class1 class2"></div>
$("#div_employee").hasClass("class1");
$("#div_employee").hasClass("class2");

Above code will return true as div has applied 2 classes as class1 and class2 in it.

$("#div_employee").hasClass("class3");

Above code will return false as there is no class3 class applied to div.
