购物车页面的设计图
商品的列表

全选的复选框
全选的代码:
<div class="footerflex"> <van-checkbox v-model="AllChecked" @click="checkAll" >全选</van-checkbox> <span class="management" v-if="managementShow" @click="management()" >管理</span> <span class="finish" v-if="finishShow" @click="management()" >完成</span> <van-button type="default" class='delete' @click="sureDel()" v-if="finishShow">删除</van-button> <div v-if="managementShow"> <span class="summation">合计</span> <i>{{ totalPrice }}</i> <van-button type="default" class="pay" @click="closeAnAccount()">结算</van-button> </div> </div>
单选的change事件
代码:
// 单选的change事件 chooseChange(id) { if (this.selectedData.indexOf(id) > -1) { this.remove(this.selectedData, id); } else { this.selectedData.push(id); } if (this.selectedData.length < this.shoppingListData.total) { this.AllChecked = false; } else { this.AllChecked = true; } console.log(this.selectedData); }
全选的JS
全选的代码:
// 全选和反选 checkAll() { let list = this.shoppingListData.rows; if (this.AllChecked) { list.forEach(element => { element.isChecked = false; }); this.selectedData = []; } else { list.forEach(element => { element.isChecked = true; if (this.selectedData.indexOf(element.goods_id) < 0) { this.selectedData.push(element.goods_id); } }); console.log(this.selectedData); } },
数组删除
