javascript - 转换成json对象标签值格式

问题描述

我有以下类型的对象：

{
    2019-02-28 02:36:20: "5 minutes"
    2019-02-28 23:59:59: "Today"
    2019-03-01 02:31:20: "+1 Day"
    2019-03-02 02:31:20: "+2 Days"
    2019-03-03 02:31:20: "+3 Days"
    2019-03-07 02:31:20: "+1 Week"
    2019-03-14 02:31:20: "+2 Weeks"
    2019-03-21 02:31:20: "+3 Weeks"
    2019-03-28 02:31:20: "+1 Month"
    2019-04-28 02:31:20: "+2 Months"
    2019-05-28 02:31:20: ">2 Months"
}

我想把它转换成：

[
   {
      label:'5 minutes',
      value:'2019-02-28 02:36:20'
   },
   {
      label:'Today',
      value:'2019-02-28 23:59:59'
   },
]

通过使用下面的这个函数，我只能得到键和值，但我无法创建那种类型的数组。请任何人都可以帮助我。

closeDate = Object.values(state.finalRequest.closeDate);
closeDateKey = Object.keys(state.finalRequest.closeDate);

解决方案

您可以使用Object.entries，然后使用map以所需的形式映射它

let obj = {"2019-02-28 02:36:20": "5 minutes","2019-02-28 23:59:59": "Today","2019-03-01 02:31:20": "+1 Day","2019-03-02 02:31:20": "+2 Days","2019-03-03 02:31:20": "+3 Days","2019-03-07 02:31:20": "+1 Week","2019-03-14 02:31:20": "+2 Weeks","2019-03-21 02:31:20": "+3 Weeks","2019-03-28 02:31:20": "+1 Month","2019-04-28 02:31:20": "+2 Months","2019-05-28 02:31:20": ">2 Months"}

let op = Object.entries(obj)
         .map(([ label, value ] ) => ({ label, value }))

console.log(op)
