一個JSON我顯示此列表中的吳重複的幫助。我想製作一個自定義過濾器，用戶可以根據他的當前位置，價格，評分和建議的自我或frd的距離（如果長和有距離）過濾列表請幫我找到解決方案

這是Plunker link

你已經做了，建立一個自定義過濾器，然後將其應用到列表 –

這就是我想知道如何讓自定義過濾器這麼多屬性？ –

首先發布你已經擁有的jsbin或jsfiddle，它可以讓你更容易地添加代碼，而不必複製你的代碼並開始新的代碼。其次是那些複合過濾器，這意味着如果用戶開始按價格過濾，然後通過評分獲得集合，那麼預期結果是按價格和評級過濾還是觸發新搜索？ – forthehackofit

您可以使用一個函數作爲filter的第一個參數，用於更復雜的過濾器。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'); 
    }

您的過濾器函數將接收當前列表項作爲其第一個參數。如果返回true，則過濾的列表將包含當前項目。

見：https://docs.angularjs.org/api/ng/filter/filter（expression參數作爲函數）的詳細信息

感謝您的答覆。你可以請編輯我的沉重的評級過濾器 –
