如何将数组数据加载到Vuetify Select输入中

Question

我正在尝试在vuetify select组件中显示“位置”，但是我当前的代码呈现“ [object Object]”而不是位置1，位置2等。

我的选择组件：

<v-select
:items="locations"
v-model="location"
label="Choose Location"
bottom
autocomplete
></v-select>

地点：

locations () {
  return this.$store.getters.getLocationsForEvent(this.event.id)
}

Vuex Getter：

getLocationsForEvent: (state) => (id) => {
  return state.loadedLocations.filter(function (location) { 
    return location.eventId === id; 
  });
}

这是位置数据的屏幕截图：

谢谢！

对于自定义对象，您必须指定item-text。该item-text是每个选项将显示什么。

例如，在您的屏幕截图中，title是一个可能的属性：

<v-select
:items="locations"
v-model="location"
label="Choose Location"
item-text="title"
bottom
autocomplete
></v-select>

下面的演示。

没有item-text：

new Vue({
  el: '#app',
  data () {
    return {
      location: null,
      locations: [
        { id: "1111", manager: 'Alice',  title: 'Water Cart 1' },
        { id: "2222", manager: 'Bob',    title: 'Water Cart 2' },
        { id: "3333", manager: 'Neysa',  title: 'Water Cart 3' }
      ]
    }
  }
})

        bottom
        autocomplete
        >
      </v-select>
    </v-container>
  </v-app>
</div>

与item-text：

new Vue({
  el: '#app',
  data () {
    return {
      location: null,
      locations: [
        { id: "1111", manager: 'Alice',  title: 'Water Cart 1' },
        { id: "2222", manager: 'Bob',    title: 'Water Cart 2' },
        { id: "3333", manager: 'Neysa',  title: 'Water Cart 3' }
      ]
    }
  }
})
