后臺給了我一個數(shù)據(jù)結(jié)構(gòu)作為表頭，我感覺不太好用，想修改一下格式。 var dateInfo = { week1_end: "2018-09-09", week1_start: "2018-09-03", week2_end: "2018-09-16", week2_start: "2018-09-10", week3_end: "2018-09-23", week3_start: "2018-09-17", week4_end: "2018-09-30", week4_start: "2018-09-24", week5_end: "2018-10-07", week5_start: "2018-10-01"};這些不太好直接循環(huán)渲染到頁面上。我想大概修改成這樣的結(jié)構(gòu)好處理了dateInfo = [ {week1_start:"2018-09-03",week1_end:"week1_end"}, {week2_start:"2018-09-03",week2_end:"week1_end"} ]一開始的思路是獲取下滑杠前面一樣的做成一個對象最后放到數(shù)組里。但是每次打印發(fā)現(xiàn)都不是想象的那樣var new_arr = []for(item in dateInfo){ // console.log(item) var str1 = item.match(/(\S*)_/)[1]; if (item.includes(str1)) { var obj = { item : dateInfo[item] } } new_arr.push(obj) }為什么會這樣啊？？？？難道是我的思路錯了嗎

代碼確實有點問題,我寫了一個

const temp = {};for (item in dateInfo) {    const val = dateInfo[item]    const str1 = item.match(/(\S*)_/)[1];    if (!temp[str1]) {
        temp[str1] = {};
        temp[str1][item] = val;
    } else {
        temp[str1][item] = val
    }
}const new_arr = Object.values(temp);console.log(new_arr);
