Reading adding and removing bg classes from Div

We often use the same Div box to communicate different type of messages. Based on the requirement ( or condition ) we can change the class associated with the DIV or P tag.
Here d1 is the id of our alert message box.

Reading the present associated class

var presentClassName = $('#d1').attr('class');

Removing one class and adding another.

$('#d1').removeClass('bg-warning').addClass( 'bg-info' );

Removing present class and adding a new class.

var presentClassName = $('#d1').attr('class');
$('#d1').removeClass( presentClassName).addClass( "bg-success" );

Here is a DEMO script to apply all classes to one DIV tag by using different buttons.
