</style>

<p class="my_text-class">This text is class='my_text-class'</p>

Reading adding and removing text classes

Based on the requirement ( or condition ) we can change the text class associated with the DIV or P tag or H 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('text-warning').addClass( 'text-info' );

Removing present class and adding a new class.

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