如何在角度 js 中使用日期过滤数据？

Question

我有学生姓名列表，我想使用两个日期过滤姓名。

我有两个日期选择器，一个用于from date，另一个用于to date。如果用户选择2015-10-19 作为from date 和2015-10-20 作为to date，那么名称列表应该显示在这两个日期之间.

以上日期选择的示例用户

列表应该是

1. 拉梅什
2. 维涅什
3. 萨拉特
4. 戈马尔

我在下面添加了我的代码，有人可以帮助我。

var nameSpace = angular.module('tst',[]);

nameSpace.controller('MyController', function MyController($scope) {
  $scope.date1 = "27-05-2010"
  $scope.date2 = "29-07-2015";
  $scope.orders = [
  {
    "date1": 1306487800,
    "date2": 1406587800
  },
  {
    "date1": 1196487800,
    "date2": 1406597800
  }]
});

// parse a date in dd-mm-yyyy format
function parseDate(input) {
  var parts = input.split('-');
  // Note: months are 0-based
  return new Date(parts[2], parts[1]-1, parts[0]); 
}

nameSpace.filter("myfilter", function() {
  return function(items, from, to) {
        var df = parseDate(from);
        var dt = parseDate(to);
        var arrayToReturn = [];        
        for (var i=0; i<items.length; i++){
            var tf = new Date(items[i].date1 * 1000),
                tt = new Date(items[i].date2 * 1000);
            if (tf > df && tt < dt)  {

您需要为此功能创建自定义过滤器功能，并将记录上的日期与用户输入的开始和结束日期进行比较。

我使用moment.js 进行日期比较，因为它是日期比较的最佳库。

HTML 代码：

 <div ng-repeat="name in names | filter: dateRangeFilter('C_Option', date2, date3)">
     <br>{{name.C_Name}}
     <br>
  </div>
  <span>{{resultsCount}} records returned</span>

JQUERY 代码：

    $scope.dateRangeFilter = function(property, startDate, endDate) {
     return function(item) {
         $scope.resultsCount = 0;
        if (item[property] === null){
          return false;
        }
        var localEndDate ='';
        if(typeof endDate === 'undefined' ){
            localEndDate =  moment(new Date(),"DD-MM-YYYY") +'T23:59:59.000Z';
        }else{
         localEndDate = endDate + 'T23:59:59.000Z';
        }

        var currentDate = moment(item[property].date.$date, "DD-MM-YYYY");
        var s = moment(startDate, "DD-MM-YYYY");
        var e = moment(localEndDate, "DD-MM-YYYY");
        if (currentDate >= s && currentDate <= e) {
            $scope.resultsCount++;
           return true;
        }
        return false;
     }
  }

更新：更新代码以显示过滤后的记录数。

Answer 3

Working Fiddle:

HTML 的变化：

<div ng-repeat="name in names | myfilter:date2:date3" >

JavaScript 更改： 添加以下自定义过滤器

moduleName.filter("myfilter", function() {
  return function(items, from, to) {

    var arrayToReturn = [];        
    for (var i=0; i<items.length; i++){   

        var test = new Date(items[i].C_Option.date.$date);
        var month = test.getMonth()+1;
        var date = test.getDate();
        var year = test.getFullYear();
        var newDate = year+"-"+month+"-"+date            
        if (newDate>= from && newDate <=  to)             {
            arrayToReturn.push(items[i]);
        }
    }

        return arrayToReturn;
  };
})
