bad87fee1348bd9aed918626	Elimina clases de un elemento con jQuery	6	18264	link https://cdnjs.cloudflare.com/ajax/libs/animate.css/3.2.0/animate.css	remove-classes-from-an-element-with-jquery

--description--

De la misma manera en que puedes agregar clases a un elemento con la función addClass() de jQuery, puedes eliminarlos con la función removeClass() de jQuery.

Así es como lo harías para un botón específico:

$("#target2").removeClass("btn-default");

Eliminemos la clase btn-default de todos nuestros elementos button.

--hints--

La clase btn-default debe ser eliminada de todos los elementos button.

assert($('.btn-default').length === 0);

Solo debes usar jQuery para eliminar esta clase del elemento.

assert(code.match(/btn btn-default/g));

Solo debes eliminar la clase btn-default.

assert(
  code.match(
    /\.[\v\s]*removeClass[\s\v]*\([\s\v]*('|")\s*btn-default\s*('|")[\s\v]*\)/gm
  )
);
