Calculating date difference with angular filter
提问by zmanc
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.
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。

JS Filter
JS过滤器
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.
HTML 来显示值。
<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>

以毫秒为单位获取两个日期之间的差异。参数是日期、单位和 usePrecision。日期默认为当前日期。例子：
<span>Difference: {{ dateFrom | amDifference : dateTo : 'days' }} days</span>
