MomentJS - Subtrair

Assim como o método add, subtract permite subtrair dias, meses, horas, minutos, segundos, etc., de uma determinada data.

Sintaxe

moment().subtract(Number, String);
moment().subtract(Duration);
moment().subtract(Object);

Observe o seguinte exemplo que mostra como usar o método de subtração -

Exemplo

         var changeddate = moment().subtract(5, 'days').subtract(2, 'months');
         document.getElementById("changeddate").innerHTML = "Subtracting 5 days and 2 month using chaining method: " + changeddate._d;
         var changeddate1 = moment().subtract({ days: 5, months: 2 });
         document.getElementById("changeddate1").innerHTML = "Subtracting 5 days and 2 month using object method: " + changeddate1._d;
         var duration = moment.duration({ 'days': 10 });
         var changeddate2 = moment([2017, 10, 15]).subtract(duration);
         document.getElementById("changeddate2").innerHTML = "Subtracting 10 days from given date using duration method: " + changeddate2._d;
      </script>
   </body>
</html>

Resultado

Para subtrair dias, meses da data que fizemos a seguir -

//chaining subtract method
var changeddate = moment().subtract(5, 'days').subtract(2, 'months');

// subtract object method
var changeddate1 = moment().subtract({ days: 5, months: 2 });

//using duration in subract method
var duration = moment.duration({ 'days': 10 });
var changeddate2 = moment([2017, 10, 15]).subtract(duration);

A saída para o mesmo é mostrada no exemplo acima.
