一旦我选择了多个服务，这就是 serviceValues 数组的样子服务值：[0,2,3,4,5,.....]

如何在 vue select 上仅显示键（youtube、facebook、whatsapp 等），然后当用户选择多个服务时，这些值应存储在 serviceValues 数组中。像 serviceValues=[0,1,2,ect...]

Answer 1

创建一个计算属性，将您的对象转换为对象列表中的对象，例如 {text: 'something', value: 2}，这在 v-select 中是必需的。

这样做：

computed: {
   options() {
      return Object.entries(this.serviceOptions)
                .map(([key, value]) => ({text: key, value: value}));
   },
},

Answer 2

创建一个将对象转换为数组的 computed 属性。

data(){
 return {
  serviceOptions:{
    "youtube":0,
    "facebook":1,
     ....
  }
 }
},
computed: {
   options() {
      return Object.entries(this.serviceOptions)
              .map(([key, value]) => ({text: key, value: value}));
   },
},

并将其绑定到 items 道具，不要忘记将 text 属性绑定到 item-text 道具。

<v-select v-model="serviceValues" :items="options" item-text="text" clearable multiple>
</v-select>
