¿Cómo habilitar/deshabilitar un botón usando jQuery?
Habilitar/deshabilitar un botón usando jQuery implica alterar su funcionalidad para aceptar o no la entrada del usuario. Esto generalmente se hace manipulando su propiedad o atributo 'deshabilitado' a través de métodos jQuery como `.prop()` o `.attr()`.
Para habilitar/deshabilitar un botón usando jQuery, necesitará una estructura HTML básica junto con JavaScript/jQuery. A continuación se muestra una estructura de código simple para comenzar
