數(shù)組格式

我目前用這個(gè)插件可以拿到數(shù)組的值，但是后臺(tái)需要我把數(shù)組的索引傳上去，搞了很久都不知道這個(gè)組件如何傳索引，當(dāng)change的時(shí)候，如何把值跟索引對(duì)應(yīng)上，下面是代碼

<mt-picker :slots="pickerSlots" @change="valuesChange"></mt-picker>

<script>
let pickerArray = {};

export default {

data() {
  return {
    showPicker: false,
    pickerSlots: [
      {
        flex: 1,
        values: Object.keys(pickerArray),
        className: 'slot1',
        textAlign: 'center'
      }
    ],
  };
},
methods: {

// 獲取pickerArray

  clickPicker: function (url) {
    this.showPicker = true;
    this.$http.get('http://59.110.236.64/' + url + '').then((response) => {
      response = response.body.data;
      pickerArray = response;
      this.pickerSlots[0].values = pickerArray;
    });
  },
  valuesChange: function (picker, values) {
    this.completeValue = values[0];
  },
}

};
</script>

萬(wàn)分感謝
