Javascript在for循环中返回对象嗨伙计答案

【发布时间】：2021-04-05 10:32:32
【问题描述】：

谁能指导我如何在 for 循环中返回一个对象？它目前在第一次迭代时退出，我知道这里不应该使用 return，但不确定我应该使用什么。

const allOrders = orderTotals && orderTotals.map((orders) => {
    
    let obj = orders['totals']
    for (const key of Object.keys(obj)) {
        return {
            x: key,
            y: obj[key].orders,
        }
    }
});

谢谢

这是 json，我正在尝试遍历总计以获取键 (X) 值和订单 (y) 值，以便创建图表。

【问题讨论】：

您能否向我们提供您想要获取的原始对象和输出对象？
是的，我刚刚添加了原始的json。谢谢
这毫无意义 - 将地图映射到另一个，但您正在循环并试图“返回”每个？你期望结果是什么？此方法只有一个输出，因此您需要合并到一个对象或数组中。
@Lee 您要查找的所需输出对象是什么？
是的，对 JS 来说很抱歉，我基本上想遍历返回键（日期）和订单值的“总计”。我无法映射，因为它不是数组，所以不确定如何获取这些值，因为键会改变我假设我不应该使用 orders['totals']['2020-03'] 等等。

【解决方案1】：

const chartData = Object.entries(data['totals']).map(([date, values]) => {
    return {x: date, y: values.orders}
  })

data 是您尝试循环的 JSON。

非常感谢，这正是我需要的
