以可在Azure移动服务（Javascript）中查询的方式保存DateTime
我想将DateTime值保存到Azure Mobile Services后端javascript，但如果将其保存为DateTime，则无法在该日期查询。我之所以要这样做，是因为我想检索特定日期范围内的所有项目。我试图将它们保存为记号，但这也不起作用，因为数值太大了以可在Azure移动服务（Javascript）中查询的方式保存DateTime,javascript,c#,datetime,azure,azure-mobile-services,Javascript,C#,Datetime,Azure,Azure Mobile Services,我想将DateTime值保存到Azure Mobile Services后端javascript，但如果将其保存为DateTime，则无法在该日期查询。我之所以要这样做，是因为我想检索特定日期范围内的所有项目。我试图将它们保存为记号，但这也不起作用，因为数值太大了 有人有想法吗？这不正确-如果在JS后端保存日期时间日期值，则可以根据该日期进行查询。所有关系操作>=，通过将它们另存为滴答声，您是指毫秒时间值吗，例如2014-12-25 UTC的1419465600000？我已经尝试了这个表。whe
