AngularJS全局日期时区偏移量 [英] AngularJS global Date timezone offset

问题描述

我正在寻找相对于用户时区的日期。

我希望Angular能够全局配置 Date 过滤器来完成此操作 - 手动执行此操作我们的时间戳已经包裹在一个 timestamp（）函数中。 （简单地乘以1000），但是如果我没有 ，我宁愿不修改该功能。

编辑：

我正在做这件事，它的工作原理，但如上所述，我想将这一级设置为更高，如果可能

  $ scope.timestamp = function（unix_time）{
 var epoch =（unix_time * 1000）; 
 var date = new Date（）; 
 var localOffset =（-1）* date.getTimezoneOffset（）* 60000; 
 var stamp = Math.round（new Date（epoch + localOffset）.getTime（））; 
返回邮票; 
}; 
  

解决方案

所以，感谢角1.4.x的更改现在是微不足道的。处理这个的正确方法是创建一个修改器，在运行之前更改内置日期过滤器。这很简单，不会对性能产生影响。

这是我使用的一个。如果没有指定时区，它只需添加一个DEFAULT_TIMEZONE。只要没有其他时区可以将应用程序中的所有日期移动到GMT。

  module.config（ ['$ provide'，function（$ provide）{
 var DEFAULT_TIMEZONE ='GMT'; 
 
 $ offers.decorator（'dateFilter'，['$ delegate'，'$ inject' ，function（$ delegate，$ inject）{
 var oldDelegate = $ delegate; 
 
 var standardDateFilterInterceptor = function（date，format，timezone）{
 if（angular.isUndefined时区））{
 timezone = DEFAULT_TIMEZONE; 
} 
 return oldDelegate.apply（this，[date，format，timezone]）; 
}; 
 
 return standardDateFilterInterceptor; 
}]）; 
}]）; 
  

I'm looking to show dates relative to the users' timezones.

My hope is that Angular has way to globally config the Date filter to do this—having to do this manually on a case-by-case basis feels wrong.

My timestamps are already wrapped in a timestamp() function (simply to multiply by 1000), but I'd prefer not to modify that function if I don't have to.

Edit:

I'm doing this, and it works, but as stated above, I'd like to set this one level higher if possible

$scope.timestamp = function (unix_time) {
    var epoch = (unix_time * 1000);
    var date = new Date();
    var localOffset = (-1) * date.getTimezoneOffset() * 60000;
    var stamp = Math.round(new Date(epoch + localOffset).getTime());
    return stamp;
};

解决方案

So, thanks to changes in angular 1.4.x this is now trivial. The proper way to handle this would be to create a decorator that alters the built in date filter before it runs. This is trivially easy, and won't have an impact on performance.

This is one I use. It simply adds a DEFAULT_TIMEZONE if no timezone is specified. This has the effect of moving all dates in the app to GMT as long as no other timezone is given.

module.config(['$provide', function($provide) {
     var DEFAULT_TIMEZONE = 'GMT';

     $provide.decorator('dateFilter', ['$delegate', '$injector', function($delegate, $injector) {
       var oldDelegate = $delegate;

       var standardDateFilterInterceptor = function(date, format, timezone) {
         if(angular.isUndefined(timezone)) {
           timezone = DEFAULT_TIMEZONE;
         }
         return oldDelegate.apply(this, [date, format, timezone]);
       };

       return standardDateFilterInterceptor;
     }]);
}]);
