/**
 * Vuetify Confirm Dialog component
 *
 * Insert component where you want to use it:
 * <confirm ref="confirm"></confirm>
 *
 * Call it:
 * this.$refs.confirm.open('Delete', 'Are you sure?', { color: 'red' }).then((confirm) => {})
 * Or use await:
 * if (await this.$refs.confirm.open('Delete', 'Are you sure?', { color: 'red' })) {
 *   // yes
 * }
 * else {
 *   // cancel
 * }
 *
 * Alternatively you can place it in main App component and access it globally via this.$root.$confirm
 * <template>
 *   <v-app>
 *     ...
 *     <confirm ref="confirm"></confirm>
 *   </v-app>
 * </template>
 *
 * mounted() {
 *   this.$root.$confirm = this.$refs.confirm.open
 * }

      this.title = title
      this.message = message
      this.options = Object.assign(this.options, options)
      return new Promise((resolve, reject) => {
        this.resolve = resolve
        this.reject = reject
      })
    },
    agree() {
      this.resolve(true)
      this.dialog = false
    },
    cancel() {
      this.resolve(false)
      this.dialog = false
    }
  }
}
</script>

If using in multiple places then confirmDialog component can be placed in root #app component like this

<div id='#app'>
  <confirmDialog :ref='store.setConfirmDialogRef' />
</div>

then in pinia store or any shared state

state: () => ({
  confirmDialogRef: null,
}),
actions: {
  setConfirmDialogRef(val) {
    this.confirmDialogRef = val;
  },
}

The store.setConfirmDialogRef method will update ref in store.
then in any function

async function submit() {
  if (!await store.confirmDialogRef.open(
    "You sure?",
    "Positive?",
  )) {
    return;
  }
  // axios.post
}
