就是把一个数组中相同类别数据，组成新的数组

效果图如上，就是把一个数组中相同类别数据，组成新的数组，每个数组最后加一个空对象，对象对应的格式要做些许改变

分店 品牌 业绩(元) 订单个数 单值(元) { {item.shopname}} { {item.shopname}} { {item.shopname}} { {item.shopname}} { {item.shopname}}

  <view class="td" style="width: 55%;" wx:if="{
   
   {item.shopname == '国安居南山店'}}">{
   
   {item.brandname}}</view>

合计 销售业绩： { {totalmoneys}} 订单个数： { {totalsnum}}

后台返回的数据结构是这样的，单这样的
我们需要对数组进行改造，把店铺名字相同的放到同一个数组，然后在每个店铺后面push一个空对象，
改造完成的数组是这样的

/js代码
///核心代码
const curData = [
{userName: ‘123’},
{userName: ‘111’},
{userName: ‘334’},
{userName: ‘222’},
{userName: ‘123’},
{userName: ‘111’},
{userName: ‘123’}
];

let dataDeal = (data) => {
let listArr = [];
data.forEach(function(value,index){
let obj = [];
for(let i=0;i<listArr.length;i++){
// 对比相同的字段key，相同放入对应的数组
if(listArr[i][0].userName == value.userName){
listArr[i].push(value);
return;
}
}
// 第一次对比没有参照，放入参照
obj.push(value);
listArr.push(obj);

});
return listArr;

};

let resultDataDeal = dataDeal(curData);
console.log(‘resultDataDeal===’+JSON.stringify(resultDataDeal));

//具体代码
let dataDeal = (data) => {
let listArr = [];
data.forEach(function (value, index) {
let obj = [];
for (let i = 0; i < listArr.length; i++) {
// 对比相同的字段key，相同放入对应的数组
if (listArr[i][0].shopname == value.shopname) {
listArr[i].push(value);
return;
}
}
// 第一次对比没有参照，放入参照
obj.push(value);
listArr.push(obj);
});
return listArr;
};
let resultDataDeal = dataDeal(res.data.data.yejilist);
let obj = {}
for (let i = 0; i < resultDataDeal.length; i++) {
obj.brandid = ‘’
obj.brandname=‘’
obj.id = i+‘’
obj.shopid = ‘’
obj.shopname =‘’
obj.tdanprice = ‘a’ //这里赋值a是因为，金额可能为0 ，可能为负数，我判断金额不等于a，就可以取反
obj.tmoneys = ‘a’
obj.tsnum = ‘a’
resultDataDeal[i].push(obj)
}
that.setData({
dataList:resultDataDeal,
totalmoneys: res.data.data.totalmoneys,
totalsnum: res.data.data.totalsnum,
})
