当值大于时,AngularJS：ng-repeat过滤器

我有一个简单的ng重复抛出数据，显示的字段之一是NumberOfStamps：

<tr ng-repeat-start="list in Data.Items ">
   <td><a href=" {[{list.Title}]} {[{list.ForeName}]} {[{list.SurName}]}</a></td>
   <td>(Date of Birth {[{list.Dob}]})</td>
   <td>{[{list.NumberOfStamps}]}  stamps</td>
</tr>

示例输出：

Mr Adam Happy  Date of Birth 01/6/1984     16 stamps
Mr Adam Sad    Date of Birth 24/11/1975    0 stamps
Mr Adam Green  Date of Birth 02/1/1963     1 stamps
Mr Adam Red    Date of Birth 21/1/1951     12 stamps
Mr Adam Blue   Date of Birth 28/10/1998    0 stamps
Mr Adam Brown  Date of Birth 25/9/2010     0 stamps
Mr Adam Black  Date of Birth 24/8/1954     21 stamps
Mr Adam Violet Date of Birth 17/5/1942     54 stamps

如何修改这个ng-repeat只显示NumberOfStams为> 0？我试过了：

<tr ng-repeat-start="list in Data.Items | filter:{NumberOfStamps > 0}">
   <td><a href=" {[{list.Title}]} {[{list.ForeName}]} {[{list.SurName}]}</a></td>
   <td>(Date of Birth {[{list.Dob}]})</td>
   <td>{[{list.NumberOfStamps}]}  stamps</td>
</tr>

预期输出：

Mr Adam Happy  Date of Birth 01/6/1984     16 stamps
Mr Adam Green  Date of Birth 02/1/1963     1 stamps
Mr Adam Red    Date of Birth 21/1/1951     12 stamps
Mr Adam Black  Date of Birth 24/8/1954     21 stamps
Mr Adam Violet Date of Birth 17/5/1942     54 stamps

在相关范围上创建谓词函数：

$scope.greaterThan = function(prop,val){
    return function(item){
      return item[prop] > val;
    }
}

作为第一个参数，它需要对象上的属性名称。第二个参数是一个整数值。

在你的视图中使用它，像这样：

<tr ng-repeat-start="list in Data.Items | filter: greaterThan('NumberOfStamps',0)">
