    [{"fupdz":"36","data":[{"id":"37","fup":"36","name":"\u5546\u5bb6\u70b9\u8bc4","px":"4","icon":"a5\/common_37_icon.png"}]},{"fupdz":"36","data":[{"id":"38","fup":"36","name":"\u623f\u5c4b\u79df\u552e","px":"5","icon":"a5\/common_38_icon.png"}]},


    如何改成
    [
    {"fupdz":"36","data":[
    {"id":"37","fup":"36","name":"\u5546\u5bb6\u70b9\u8bc4","px":"4","icon":"a5\/common_37_icon.png"},
    {"id":"38","fup":"36","name":"\u623f\u5c4b\u79df\u552e","px":"5","icon":"a5\/common_38_icon.png"}
    ]
    },

    的这个形式 前面相同然后合并在一起

    唯一方式:遍历重构

    循环,然后判断 fupdz 一致则放一起

    @qiayue 循环采用的是数据库的 while

    ```javascript
    const sort = (arr) => {
    let hash = {}
    let newArr = []
    let i = 0
    for (let item of foo) {
    if (hash[item.fupdz] == undefined) {
    hash[item.fupdz] = i
    newArr.push(item)
    i++
    } else {
    const idx = hash[item.fupdz]
    const data = item.data
    data.forEach(item => newArr[idx].data.push(item))
    }
    }
    return newArr
    }
    ```
    这样写应该没问题,楼主试试
