一个JSON我显示此列表中的吴重复的帮助。我想制作一个自定义过滤器，用户可以根据他的当前位置，价格，评分和建议的自我或frd的距离（如果长和有距离）过滤列表请帮我找到解决方案

你已经做了，建立一个自定义过滤器，然后将其应用到列表 –

这就是我想知道如何让自定义过滤器这么多属性？ –

首先发布你已经拥有的jsbin或jsfiddle，它可以让你更容易地添加代码，而不必复制你的代码并开始新的代码。其次是那些复合过滤器，这意味着如果用户开始按价格过滤，然后通过评分获得集合，那么预期结果是按价格和评级过滤还是触发新搜索？ – forthehackofit

您可以使用一个函数作为filter的第一个参数，用于更复杂的过滤器。例如，您可以在控制器中指定：

$scope.filterFn = function (o) { 
     return (o.price > 10) && ((o.longitude - user.longitude) < 2) && (o.itemType === 'Business'); 
    }

您的过滤器函数将接收当前列表项作为其第一个参数。如果返回true，则过滤的列表将包含当前项目。

见：https://docs.angularjs.org/api/ng/filter/filter（expression参数作为函数）的详细信息
