如何将数组数据加载到 Vuetify Select 输入中

Question

我试图在 vuetify select 组件中显示 "locations"，但我当前的代码呈现“[object Object]”而不是位置 1、位置 2 等

我的select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！

Answer 1

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，根据您的屏幕截图，title 是可能的属性:

<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>

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' }
      ]
    }
  }
})

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

实现了具有低级对象数组的手表

watch: {
    groupInfo: function(groupInfo) {
      if (groupInfo.teams !== undefined) {
        var newArray = [];
        for (var key in groupInfo.teams) {
          var obj = groupInfo.teams[key];
          newArray.push(obj);
        }
        console.log("wagwan" newArray)
        this.teams = newArray;
      }
    }
  },
