I want to remove the css class of an element when a method is called. but I want to do this using $refs.

template:

  <div class="modal"  ref="myModal"></div>

method:

      closeDropdown: function() {
            this.$refs.myModal.$el.removeClass("open");
      }

CodePudding user response：

this.$refs.myModal.classList.remove("open");

Two steps:

1. const modalElement = this.$refs.myModal; // reference to the DOM element
2. modalElement.classList.toggle("custom"); // use classList API of DOM element

classList API reference: https://developer.mozilla.org/en-US/docs/Web/API/Element/classList, you can use this API to modify its classes using the add(), remove(), replace(), and toggle() methods.
