Question

我有以下型号，并希望显示过去24小时内投票的最高价

    {
    "_id": {
        "$oid": "56abe20fabd3fa64187b5d21"
    },
    "user": {
        "$oid": "56a1832a36dc3d0e00c7aa3f"
    },
    "title": "Intel Pentium i5 Quad-Core i5-6400",
    "created": {
        "$date": "2016-01-29T22:05:03.574Z"
    },
    "votes": 1
}

所以基本上在过去24小时内将ng-repeat限制为创建的字段。

过滤

angular.module('savings').filter('lessThan', function () {
    return function(savings, requirement) {
        var filterKey = Object.keys(requirement)[0];
        var filterVal = requirement[filterKey];



        var filtered = [];


        if(filterVal !== undefined && filterVal !== ''){
            angular.forEach(savings, function(saving) {
                var today = new Date();

                var date = new Date(saving.created.$date);

                var diff = today - date;

                diff = diff / (1000*60*60);

                if(diff < filterVal) {
                    filtered.push(saving);
                }
            });
            alert(filtered.length);
            return filtered;



}

    return savings;

};

}）;

我已尝试实施以下答案，但它不会返回任何结果。

我会节省你一些时间..这是你的过滤器。

app.filter('lessThan', function () {
 return function(items, requirement) { 
  var filterKey = Object.keys(requirement)[0];
  var filterVal = requirement[filterKey];    

  var filtered = [];    

  if(filterVal !== undefined && filterVal !== ''){      
    angular.forEach(items, function(item) {
      var today = new Date();
      var date = new Date(item.created)
      var diff = today - date;
      diff = diff / (1000*60*60)

      if(diff < filterVal) {
        filtered.push(item);
      }
    });
    return filtered; 
  }        

  return items;
  };
 });

并称之为：

<div ng-repeat="item in items | lessThan: {'created':24}">

Here是一名掠夺者。

编辑：根据截图创建的属性看起来更像是这样：

"created": "2016-01-29T22:05:03.574Z"
