图表的日期范围

Question

我正在尝试从日期时间组件中获取startDate和endDate，并针对图表运行它：以["2018-11-29T20:41:28.449Z","3"]格式保存vuex存储中值数组的数据是返回a的最佳方法计算属性？

  <template>
    <div class="b-container">
        <br />
        <h2>Probe Charts</h2>
        <ul v-for="(photon,key) in this.$store.state.photons">
            <h3>Photon: {{key}}</h3>
            <b-row>
                <b-col>
                    <datetime type='datetime' v-model="photon.startDate" use12-hour auto class="theme-orange">
                        <label for="startDate" slot="before" placeholder="">Start Datetime:</label>
                    </datetime>
                </b-col>
                <b-col>

                    </datetime>

        methods: {

        computed:{
