数组遍历完成设置data总是空 - WXOPEN Club

打印squareLists是空

getSquareList是个异步操作哦。你把 that.setData写到 squareItem[item.square_id] = res 的后面一排

你需要这样写

async function yourHandleDataFunction() {

if (res.statusCode == 200) {

...

const squareItems = {}

await Promise.all(res.data.map((item, index) => async () {

const data = await that.getSquareList(item.square_id)

squareItems[item.square_id] = data

})

that.setData(...)

}
