訂單數組如何按日期和時間降序？

Question

我有對象數組：

[{id:'124',name:'ttt', MeasureDate:"2015-04-05T18:46:38"}, 
 {id:'589',name:'mmm', MeasureDate:"2015-05-05T18:46:38"}, 
 {id:'45',name:'yyy' , MeasureDate:"2016-01-05T18:46:38"},
 {id:'567',name:'eee', MeasureDate:"2016-05-05T18:46:38"}]

我沒有按date and time降序排列數組：

[{id:'567',name:'eee', MeasureDate:"2016-05-05T18:46:38"},
 {id:'45',name:'yyy' , MeasureDate:"2016-01-05T18:46:38"},
 {id:'589',name:'mmm', MeasureDate:"2015-05-05T18:46:38"},
 {id:'124',name:'ttt', MeasureDate:"2015-04-05T18:46:38"}]

如何在javascript中實現它？

Answer 1

您可以使用sort和Date.parse

 var data = [{id:'124',name:'ttt', MeasureDate:"2015-04-05T18:46:38"}, {id:'589',name:'mmm', MeasureDate:"2015-05-05T18:46:38"}, {id:'45',name:'yyy' , MeasureDate:"2016-01-05T18:46:38"}, {id:'567',name:'eee', MeasureDate:"2016-05-05T18:46:38"}]; var sorted = data.sort(function(a, b) { return Date.parse(b.MeasureDate) - Date.parse(a.MeasureDate); }); console.log(sorted) 

Answer 2

只需使用sort和String#localeCompare對其進行排序。

當日期是ISO6801並且是可排序的字符串時，這是可能的。

 var array = [{id:'124',name:'ttt', MeasureDate:"2015-04-05T18:46:38"}, {id:'589',name:'mmm', MeasureDate:"2015-05-05T18:46:38"}, {id:'45',name:'yyy', MeasureDate:"2016-01-05T18:46:38"}, {id:'567',name:'eee', MeasureDate:"2016-05-05T18:46:38"}]; array.sort(function (a, b) { return b.MeasureDate.localeCompare(a.MeasureDate); }); console.log(array);
