    <div style="background-color:yellow;margin-top:10px" v-for="(el,index) in getArrary" :key="index" @click="sendId(el.id)">{{el.id}}</div>
    <Good :send='data'></Good>
    </div>
</template>
<script>
import Good from './good'
export default {
  name: 'helloworld',
  components: { Good },
  data () {
    return {
      getList: {
        data: 'ok'
      },
      data:'',
      getArrary:[
        {
           id:
        },
        {
           id:
        },
        {
           id:

        },
        {

  methods: {
    sendId:function(item){
      this.data=item
    }
