Question

我的问题是关于使用时间和日期进行排序。

这是我的数组对象：

[
    {
       exercise_description:"SDA",
       exercise_id:"13",
       exercise_name:"WEIGHT",
       exercise_time:"09:30 AM",
       workout_date:"2016-02-15",
       workout_desc:"SAMPLE"
    },
    {
       exercise_description:"SDA",
       exercise_id:"13",
       exercise_name:"ASA",
       exercise_time:"09:30 AM",
       workout_date:"2016-02-15",
       workout_desc:"kk"
    },
    {
       exercise_description:"dsf",
       exercise_id:"14",
       exercise_name:"vajrasanam",
       exercise_time:"03:45 AM",
       workout_date:"2016-02-15",
       workout_desc:"rfsgfrds"
    },
    {
       exercise_description:"fds",
       exercise_id:"12",
       exercise_name:"fsdd",
       exercise_time:"01:15 PM",
       workout_date:"2016-02-16",
       workout_desc:"dda"
    }
]

我想对此进行排序，例如

[
    {
       exercise_description:"dsf",
       exercise_id:"14",
       exercise_name:"vajrasanam",
       exercise_time:"03:45 AM",
       workout_date:"2016-02-15",
       workout_desc:"rfsgfrds"
    },
    {
       exercise_description:"SDA",
       exercise_id:"13",
       exercise_name:"WEIGHT",
       exercise_time:"09:30 AM",
       workout_date:"2016-02-15",
       workout_desc:"SAMPLE"
    },
    {
       exercise_description:"SDA",
       exercise_id:"13",
       exercise_name:"ASA",
       exercise_time:"09:30 AM",
       workout_date:"2016-02-15",
       workout_desc:"kk"
    },
    {
       exercise_description:"fds",
       exercise_id:"12",
       exercise_name:"fsdd",
       exercise_time:"01:15 PM",
       workout_date:"2016-02-16",
       workout_desc:"dda"
    }
]

我该如何排序？

Answer 1

所以我觉得这必须要做到这一点。

  var  arrayData =  [ 
 { exercise_description:"SDA", 
 exercise_id:"13", 
 exercise_name:"WEIGHT",
 exercise_time:"09:30 AM",
 workout_date:"2016-02-15", 
 workout_desc:"SAMPLE" 
 }, 
 { exercise_description:"SDA",
 exercise_id:"13", 
 exercise_name:"ASA",
 exercise_time:"09:30 AM",
 workout_date:"2016-02-15", 
 workout_desc:"kk" 
 }, 
 { exercise_description:"dsf",
 exercise_id:"14", 
 exercise_name:"vajrasanam", 
 exercise_time:"03:45 AM", 
 workout_date:"2016-02-15",
 workout_desc:"rfsgfrds" 
 }, 
 {
exercise_description:"fds",
exercise_id:"12",
exercise_name:"fsdd",
exercise_time:"01:15 PM",
workout_date:"2016-02-16",
workout_desc:"dda"
}
];

 //this must sort the array as you requested
 var sortedData = arrayData .sort(function(a,b){  
          return new Date(a.workout_date  + ' ' +  a.exercise_time) - new Date(b.workout_date  + ' ' +  b.exercise_time);
     });

确保使用尽可能多的数据集来检查此逻辑，以确保其稳定。

Answer 2

在JS日期中，跨浏览器可能会出现问题，momentJS可以使用简单的array.sort方法解决问题。

var sorted = unsorted.sort(function(a,b) {
  var aDate = moment(a.workout_date + ' ' +a.exercise_time).unix();
  var bDate = moment(b.workout_date + ' ' +b.exercise_time).unix();

  if(aDate < bDate) {
    return -1;
  }

  if(aDate > bDate) {
    return 1;
  }

  return 0;

});

我想基于json数组排序时间
