Using a mixin on two components: it calls the method on only the first component

624 views Asked by At

I have two components that need to share a method. I used a mixin for this method and added the mixin to both components. When I click on the second component it fires off the method on the first component instead of the second one - in this case, it opens the top drop down and not the second drop down.

Here is a snippet of my code...

// Mixins

var showDropdownMixin = {
  data() {
    return {
      activeTrigger: false,
      dropdown: false
    }
  },
  methods: {
    showDropdown: function(){
      if(this.dropdown == false){
        this.dropdown = true;
        this.activeTrigger = true;
        TweenMax.fromTo(
          "#dropdown",
          0.55,
          {
            autoAlpha: 0,
            y: -10
          },
          {
            autoAlpha: 1,
            y: 0,
            ease: Power2.easeOut
          }
        );
      }else{
        this.dropdown = false;
        this.activeTrigger = false;
         TweenMax.to(
          "#dropdown",
          0.2,
          {
            autoAlpha: 0,
            y: -10,
            ease: Power2.easeOut
          });
      }

    }
  }
}

You have two elements with the same id: dropdown. It looks like TweenMax queries the built page to find where to attach the menu, and just goes with the first one it finds.

You might make the id for each element unique, and pass the id as a parameter on your showDropdown method.
