javascript - 如何在模态中显示v-for中点击元素的vue数据

Question

这就是我的 json 的样子。我以 v-for 格式显示其中一堆，并且可以单击其中一个。我想显示我在模式中单击的元素中的数据。

[{
        "id": 1,
        "companyName": "test",
        "image": "https://mmelektronik.com.pl/wp-content/uploads/2017/10/Insert-logo.jpg.png",
        "location": "Warsaw",
        "salary": "10000",
        "skill": "Junior",
        "tags": "test",
        "jobDescription": "test",
        "title": "UI Designer"
    }

]    

Now I want to access only jobDescription and display it in the modal.

b-modal(hide-footer="", :id="id")
      template(#modal-title="")
        | Information
      .d-block.text-center
        p {{ want the jobDescription here }}
        b-button(variant="primary") Apply

这就是我打开模式的方式。

  openModal(item) {
      this.offer = item;
      this.$bvModal.show(this.id);
    }

组件

  b-container
    b-card.joblist__post.mt-2(
      v-for="offer in filteredOffers",
      :id="id"
      :key="offer.id",
      @click="openModal"
    )
      .d-flex
        .joblist.d-flex.w-100
          .joblist__info.d-flex.align-items-center
            .company-logo.d-flex.align-items-center.mr-3
              b-img.logo(:src="offer.image")
            .joblist-name.d-flex.flex-column.text-left
              h5.mb-0.font-weight-bold {{ offer.title }}
              .located.d-flex.align-items-center.mt-2.justify-content-start
                b-icon.mr-2(icon="geo-alt-fill")
                p.m-0.text-secondary.joblist-span {{ offer.location }}
                b-icon.mx-2(icon="person-fill")
                p.m-0.text-secondary.joblist-span {{ offer.companyName }}
                b-icon.mx-2(icon="bar-chart-fill")
     

    b-modal(hide-footer="", :id="id")
      template(#modal-title="")
        | Information 
      .d-block.text-center
        p {{offer.jobDescription}}
      b-button(variant="primary") Ok


export default {
  data() {
    return {
      search: "",
    };
  },
  computed: {
    ...mapState({
      offers: (state) => state.offer.offers,
      loading: (state) => state.offer.loading
    }),
 
    filteredOffers(){
      return this.offers.filter((offer) => {
        return offer.title.match(this.search);
      })
      
    },

  },
  methods: {
    ...mapActions({
      fetchOffers: "fetch",
    }),
    openModal(item) {
      this.offer = item;
      this.$bvModal.show(this.id);
    }
  },
  mounted() {
    this.fetchOffers();
    this.id = this._uid;
},
  
};

Answer 1

这是您可以采用的简单方法。在数据中有一个 selectedItem 属性，如下所示:

data: {
   return {
      selectedItem: {}
   }
}

并在元素上添加单击，如下所示，将单击的对象分配给 selectedItem:

<button v-for="(e, i) in whateverDataArray" :key="i" @click="selectedItem=e">
    {{ e.companyName }}
</button>

然后只需将 selectedItem 作为 props 传递给模态框，这样当模态框出现时，它将显示单击的 selectedItem 的 props!

编辑:在您的情况下，您也应该从 for 循环中删除模式。此外，您不需要将 selectedItem 作为属性传递给模式，因为您可以访问 selectedItem。
