本文实例讲述了微信小程序实现多选框全选与取消全选功能。分享给大家供大家参考，具体如下：

js部分：

page({
data: { select_all:false,
listData: [{code: "111",text: "text1",typ: "type1",},
{code: "021",text: "text2",typ: "type2",},
{code: "111",text: "text1",typ: "type3",}]}
selectall: function() {//全选与反全选
var that = this;
for (let i = 0; i < that.data.listData.length; i++) {
that.data.listData[i].checked = (!that.data.select_all)}
that.setData({
listData: that.data.listData,
select_all: (!that.data.select_all)
})}
})

wxml部分：

<view class="scroll">
<scroll-view scroll-x="true">
<checkbox-group class="table" >
<view class="tr">
<view class="th">
<checkbox value="all" bindtap="selectall" />全选
</view>
<view class="th">运号</view>
<view class="th">V号</view>
<view class="th">运商</view>
<view class="th">返单</view>
<view class="th">日期</view>
</view>
<view class="tr" wx:for="{{listData}}" wx:key="">
<view class="td">
<checkbox value="{{item.code}}" checked="{{item.checked}}" />
</view>
<view class="td" value="{{item.text}}">{{item.code}}</view>
<view class="td" value="{{item.text}}">{{item.text}}</view>
<view class="td" value="{{item.typ}}">{{item.typ}}</view>
<view class="td" value="{{item.typ}}">{{item.typ}}</view>
<view class="td" value="{{item.typ}}">{{item.typ}}</view>
</view>
</checkbox-group>
</scroll-view>
</view>
</view>

wxss部分：

.table{
background-color: #fff;
border:1px solid #dadada;
width:1200rpx;
margin-left:0rpx;
}
.tr{
background-color: #dadada;
white-space: nowrap;
width:100%;
display: flex;
text-align: center;
justify-content: center;
}
.th{
background-color: #fff999;
text-align: center;
justify-content: center;
width: 100%;
border-bottom: 1px solid #dadada;
border-right: 1px solid #dadada;
