这篇文章主要介绍了微信小程序全选多选效果实现代码解析,文中通过示例代码介绍的非常详细，对大家的学习或者工作具有一定的参考学习价值,需要的朋友可以参考下
效果图：
wxml代码：
<view> <view bindtap='selectAll'> <checkbox checked="{{selectilall}}"/> <text>全选</text> </view> <view wx:for="{{list}}"> <view data-index="{{index}}" data-name="{{item.id}}" bindtap='select'> <checkbox checked="{{item.checked}}"/> <image src="" mode="widthFix"></image> <view> <view>汪小涵 <text>管理员</text> </view> <view>总监</view> </view> </view> </view> </view>
wxss代码：
.memberList{ background:#fff; padding:0 35rpx 0 28rpx; } .allSelect_box{ line-height:90rpx; border-bottom:1rpx solid #F5F5F5; } .checkbox{ transform: scale(0.7,0.7); } .member_box .checkbox{ margin-top: 15rpx; } checkbox .wx-checkbox-input.wx-checkbox-input-checked { color:#fff; background: #6669e3; border-color:#6669e3; } .allSelect{ margin-left:15rpx; vertical-align:middle; } .member_box{ padding-bottom:30rpx; display: flex; border-bottom:2rpx solid #EBEBEB; padding:20rpx 0 20rpx 0; } .avatar{ width:100rpx; border-radius:50%; margin-left:15rpx; } .applicant_name{ font-size:34rpx; padding:0 0 15rpx 30rpx; } .applicant_name text{ color:#fff; background:#6669e3; font-size:28rpx; padding:5rpx 10rpx; border-radius:10rpx; margin-left:15rpx; } .approval_state{ color:#8D8D8D; font-size:28rpx; padding-left: 30rpx; }
js代码：
data: { list: [ { id: 1, name: 1, checked: false }, { id: 2, name: 2, checked: false }, { id: 3, name: 3, checked: false }, { id: 4, name: 4, checked: false }, ], selectilall: false },
//单选 select: function (e) { let selectValue = e.currentTarget.dataset.name let index = e.currentTarget.dataset.index; let list = this.data.list let newli = 'list[' + index + '].checked'; this.setData({ [newli]: !this.data.list[index].checked }) let num = 0; for(var i=0;i<this.data.list.length;i++){ if(this.data.list[i].checked){ num++; } } if(num == this.data.list.length){ this.setData({ selectilall: true }) }else{ this.setData({ selectilall: false }) } }, //全选，取消全选 selectAll: function (e) { let list = this.data.list; let selectilall = this.data.selectilall; if (selectilall == false) { for (let i = 0; i < list.length; i++) { let newli = 'list[' + i + '].checked'; this.setData({ [newli]: true, selectilall: true }) } } else { for (let i = 0; i < list.length; i++) { let newli = 'list[' + i + '].checked'; this.setData({ [newli]: false, selectilall: false }) } } }
