vue.js - 如何将数组数据加载到 Vuetify 选择输入

Question

我试图在 vuetify 选择组件中显示“位置”，但我当前的代码呈现“[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 setter/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。 item-text 是每个选项将显示的内容。

例如，从您的屏幕截图来看，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' }
      ]
    }
  }
})

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

使用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' }
      ]
    }
  }
})

        item-text="title"
        bottom
        autocomplete
        >
      </v-select>

  </v-app>
