vuejs 배열에서 항목삭제하기

Posted at

기존방식같기는 하지만 부모컴포넌트에서 자식컴포넌트에 이벤트를 전달하는 방식

HomeVue.vue
<template>
  <v-container>
    <v-col>
      <ListView
        :todolist="todolist"
        @statusControl="statusControl"
        @deleteItem="deleteItem"
        @editItem="editItem"
      />
    </v-col>
    <v-col>
      <ListAdd @listAdd="listAdd" />
    </v-col>
  </v-container>
</template>

<script>
import ListAdd from '@/components/ListAdd.vue';
import ListView from '@/components/ListView.vue';
export default({
  name: 'HomeView',
  components: {
    ListAdd,
    ListView

  },
  data() {
    return {
      todolist : [],
    }
  },
  methods : {
    deleteItem(index){
      this.todolist.splice(index,1)
    },
  }
});
</script>

Vuex store 를 활용해서 배열삭제하기

  1. 삭제할 배열을 담을 items[]선언한다.
  2. mutation 에서 delItem(state, index) 함수를 만든다,.
  3. mutation 에서 만든 함수를 action 애서 불러온다.
import Vue from "vue";
import Vuex from "vuex";

Vue.use(Vuex);
Vue.config.devtools = true;
export default new Vuex.Store({
  namespaced: true,
  state: {
    //data 삭제할 아이템을 담는 배열 선언
    items: [],
  },
  mutations: {
    delItem(state, index) {
      state.items.splice(index, 1);
    },
  },
  actions: {
    delItem({ commit }, id) {
      commit("delItem", id);
    },
  },
});

실제 장바구니에 담긴 상품을 삭제하는 component

CartList.vue
<template>
  <div>
    <div class="header-cart header-dropdown">
      <ul class="header-cart-wrapitem">
        <template v-for="(item, index) in items">
          <li :key="index" class="header-cart-item">
            <div class="header-cart-item-img" @click="delItem(index)">
              <img :src="item.image" alt="IMG" />
            </div>
          </li>
        </template>
      </ul>     
    </div>
  </div>
</template>

<script>
import { mapState, mapGetters } from "vuex";

export default {
  computed: {
    ...mapState(["items"]),
    ...mapGetters(["totalPrice", "totalQty"]),
  },
  created() {},
  methods: {
//스토어에 접근해서 dispatch를 통해서 스토어에 있는 함수 delItem을 불러온다.
    delItem(index) {
      this.$store.dispatch("delItem", index);
    },
  },
};
</script>
