javascript如何循环把对象变成数组形式？

Question

后端提供数据如下

[{avgInvestIndex:0,avgprice:3333},{avgInvestIndex:0,avgprice:3333},{avgInvestIndex:0,avgprice:3333},{avgInvestIndex:0,avgprice:3333},.......{avgInvestIndex:0,avgprice:3333}]

我想要的效果

[0,3333],[0,3333],[0,3333],[0,3333],[0,3333],.....[0,3333]

这是我的方法

let newbox = [];
  for (let i = 0; i < _this.artdata.length; i++) {
    newbox.push([]);
    newbox[i].push(_this.artdata[i].avgInvestIndex + ',' + _this.artdata[i].avgPrice)
   }

输出的是

["0,3333"]，["0,3333"]，["0,3333"]，["0,3333"]，["0,3333"]，["0,3333"]

但是我想要的是数字格式，请问这种情况下如何处理，感谢

Answer 1

_this = {};
_this.artdata=[{avgInvestIndex:0,avgprice:3333},{avgInvestIndex:0,avgprice:3333},{avgInvestIndex:0,avgprice:3333},{avgInvestIndex:0,avgprice:3333},{avgInvestIndex:0,avgprice:3333}];


let newbox = [];
for (let i = 0; i < _this.artdata.length; i++) {
    newbox.push([_this.artdata[i].avgInvestIndex, _this.artdata[i].avgprice]);
}

楼上很多代码都能解决问题了。。。

Answer 2

arr.map(item => Object.values(item))
不考虑兼容性的话，这样就可以了

Answer 3

[{avgInvestIndex:0,avgprice:3333},{avgInvestIndex:0,avgprice:3333},{avgInvestIndex:0,avgprice:3333},{avgInvestIndex:0,avgprice:3333},{avgInvestIndex:0,avgprice:3333}].map(d=>Object.values(d))

Answer 4

newbox.push(_this.artdata[i].avgInvestIndex, _this.artdata[i].avgPrice)

Answer 5

谢邀！

根据你的思路，把push直接改为赋值就行了

newbox[i]=[_this.artdata[i].avgInvestIndex, _this.artdata[i].avgPrice]

当然，楼上的map方式更好

Answer 6

let newbox = [];
  for (let i = 0; i < _this.artdata.length; i++) {
/*
    newbox.push([]);
    newbox[i].push(_this.artdata[i].avgInvestIndex + ',' + _this.artdata[i].avgPrice)
    //上面是你的代码*/
    tmp=[_this.artdata[i].avgInvestIndex , _this.artdata[i].avgPrice];
    newbox.push(tmp);
   }

其实你就差一步啊

Answer 7

newbox = arr.map(a => [
  a.avgInvestIndex,
  a.avgprice,
])
