In order to change the CSS class applied to an element using jQuery we can use methods like
addClass() and .removeClass()

$("#divId").addClass("classname");

$("#divId").removeClass("classname");

But if we want to change or toggle CSS class between two classes during some events like button click we can use method toggleClass() like below.

Say on click we need to change class from "btn_submit" and "btn_submit_active" or vise versa
if element has class "btn_submit_active" toggle to use "btn_submit". here we use toggleClass() method twise.

  $("#divId").toggleClass("btn_submit");
  $("#divId").toggleClass("btn_submit_active");
