[Vuejs]-Getting target element from method (without event)

You can use $refs like this to to target specific elements

<sidebar-link ref="fancySidebarLink" />

methods: {
   isActive(e) {
      console.log(this.$refs.fancySidebarLink)
   }
}

You could also v-for on all of your sidebar links and call your initial function on each iteration! (isActive)
