使用角度过滤器计算日期差异 [英] Calculating date difference with angular filter

问题描述

我需要能够计算两天之间的差异(包括两天)并显示差异.理想情况下，这将通过角度过滤器进行，因此它可以在整个应用程序中使用.

解决方案

JS 过滤器

generalFilters.filter('dateDiff', function () {var magicNumber = (1000 * 60 * 60 * 24);返回函数(toDate，fromDate){if(toDate && fromDate){var dayDiff = Math.floor((toDate - fromDate)/magicNumber);如果(angular.isNumber(dayDiff)){返回 dayDiff + 1;}}};});

HTML 来显示值.

{{entry.toStr |dateDiff:entry.fromStr}} <ng-pluralize count="entry.toStr | dateDiff:entry.fromStr" when="{1:'Day', other: 'Days'}"></ng-pluralize></div>

I needed to be able to calculate the difference between two days, inclusive, and display the difference. Ideally this would be via an angular filter so it can be used all over the application.

解决方案

JS Filter

generalFilters.filter('dateDiff', function () {
  var magicNumber = (1000 * 60 * 60 * 24);

  return function (toDate, fromDate) {
    if(toDate && fromDate){
      var dayDiff = Math.floor((toDate - fromDate) / magicNumber);
      if (angular.isNumber(dayDiff)){
        return dayDiff + 1;
      }
    }
  };
});

HTML to display the value.

<div class="field-value">{{entry.toStr | dateDiff:entry.fromStr}} <ng-pluralize count="entry.toStr | dateDiff:entry.fromStr" when="{1:'Day', other: 'Days'}"></ng-pluralize></div>
