javascript - 如何根据值获取键而不重复

Question

我有一种情况，我只想获得 key 及其时间确定，即 am 或 pm

这是我的数据

    var  amUserDate = {"monday|am":false,"tuesday|am":true,"wednesday|am":false,"thursday|am":false,"friday|am":false,"saturday|am":true,"sunday|am":false};

   var   pmUserDate = {"monday|pm":true,"tuesday|pm":false,"wednesday|pm":false,"thursday|pm":false,"friday|pm":false,"saturday|pm":false,"sunday|pm":true};

我想要的输出:

基于 true(value) 的 key => value 对结果将如下所示

amAvailibility  = [{"day":"tuesday","time":"am"},{"day":"saturday","time":"am"}];


pmAvailibility  = [{"day":"monday","time":"pm"},{"day":"sunday","time":"pm"}];

请提前帮助我谢谢!!!

你可以使用这段代码来实现你想要的:

 var  amUserDate = {"monday|am":false,"tuesday|am":true,"wednesday|am":false,"thursday|am":false,"friday|am":false,"saturday|am":true,"sunday|am":false};

var pmUserDate = {"monday|pm":true,"tuesday|pm":false,"wednesday|pm":false,"thursday|pm":false,"friday|pm":false,"saturday|pm":false,"sunday|pm":true};

var amKeys = Object.keys(amUserDate),
    pmKeys = Object.keys(pmUserDate),
    amAvailibility = [],
    pmAvailibility = [];

amKeys.forEach(function(key, index){
   var obj = {};
   if(amUserDate[key]){
     var splitStr = key.split('|');
     obj = {day: splitStr[0], time: splitStr[1] }
     amAvailibility.push(obj);
   }
});

pmKeys.forEach(function(key, index){
   var obj = {};
   if(pmUserDate[key]){
     var splitStr = key.split('|');
     obj = {day: splitStr[0], time: splitStr[1] }
     pmAvailibility.push(obj);
   }
});

console.log(amAvailibility);
console.log(pmAvailibility);
