VUE 笔记 ilovecoding 216~217 购物车商品列表 item 及其是否选中

一. 增加组件 CheckButton.vue 及其需要的图片

<template>
  <div class="check-button" :class="{check: isChecked}">
    <img src="~assets/img/cart/tick.svg" alt="">
  </div>
</template>

<script>
  export default {
    name: 'CheckButton',
    props: {
      isChecked: {
        type: Boolean,
        default: false
      }
    }
  }
</script>

<style scoped>
  .check-button {
    border-radius: 50%;
    border: 2px solid #aaa;
  }

  .check {
    border-color: red;
    background-color: red;
  }
</style>

二. 调整 CartListItem.vue

<template>
  <div id="shop-item">
    <div class="item-selector">
      <CheckButton :is-checked="itemInfo.checked" @click="checkClick"/>
    </div>
    <div class="item-img">
      <img :src="itemInfo.image" alt="商品图片"/>
    </div>
    <div class="item-info">
      <div class="item-title">{{itemInfo.title}}</div>
      <div class="item-desc">{{itemInfo.desc}}</div>
      <div class="info-bottom">
        <div class="item-price left">￥{{itemInfo.price}}</div>
        <div class="item-count right">X{{itemInfo.count}}</div>
      </div>
    </div>
  </div>
</template>

<script>

  import CheckButton from 'components/content/checkButton/CheckButton'

  export default {
    name: 'CartListItem',
    components: {
      CheckButton
    },
    props: {
      itemInfo: {
        type: Object,
        default() {
          return {}
        }
      }
    },
    methods: {
      checkClick() {
        this.itemInfo.checked = !this.itemInfo.checked;
      }
    }
  }
</script>

<style scoped>
  #shop-item {
    width: 100%;
    display: flex;
    font-size: 0;
    padding: 5px;
    border-bottom: 1px solid #ccc;
  }

  .item-selector {
    width: 20px;
    display: flex;
    justify-content: center;
    align-items: center;
  }

  .item-title, .item-desc {
    overflow: hidden;
    white-space: nowrap;
    text-overflow: ellipsis;
  }

  .item-img {
    padding: 5px;
  }

  .item-img img {
    width: 80px;
    height: 100px;
    display: block;
    border-radius: 5px;
  }

  .item-info {
    font-size: 17px;
    color: #333;
    padding: 5px 10px;
    position: relative;
    overflow: hidden;
  }

  .item-info .item-desc {
    font-size: 14px;
    color: #666;
    margin-top: 15px;
  }

  .info-bottom {
    margin-top: 10px;
    position: absolute;
    bottom: 10px;
    left: 10px;
    right: 10px;
  }

  .info-bottom .item-price {
    color: orangered;
  }
</style>

三. 调整 CartList.vue

<template>
  <div class="cart-list">
    <scroll class="cart-list-scroll-content"
      ref="scroll"
      :probe-type="3">
      <cart-list-item v-for="(item, index) in cartList" 
        :key="index" 
        :item-info="item"/>
    </scroll>
  </div>
</template>

<script>

  import Scroll from 'components/common/scroll/Scroll'
  import CartListItem from './CartListItem'

  import { mapGetters } from 'vuex'

  export default {
    name: 'CartList',
    components: {
      Scroll,
      CartListItem
    },
    computed: {
      ...mapGetters(['cartList'])
    },
    activated() {
      this.$refs.scroll.refresh()
    }
  }
</script>

<style scoped>
  .cart-list {
    height: calc(100% - 44px - 49px);
  }
  .cart-list-scroll-content {
    height: 100%;
    overflow: hidden;
  }
</style>

四. 调整 mutations.js

import {
  ADD_COUNTER,
  ADD_TO_CART
} from './mutation-types'

export default {
  [ADD_COUNTER](state, payload) {
    payload.count++;
  },
  [ADD_TO_CART](state, payload) {
    payload.checked = true;
    state.cartList.push(payload);
  }
}
