Replace Div Content onclick

Question

I know nothing about jQuery but want to achieve something really important.

I want to have a button/link that will replace the div content and if I press that button

Answer 1

A simple addClass and removeClass will do the trick on what you need..

$('#change').on('click', function() { 
  $('div').each(function() { 
    if($(this).hasClass('active')) { 
        $(this).removeClass('active');
    } else { 
        $(this).addClass('active');
    }
});

});

Seee fiddle

I recommend you to learn jquery first before using.
