javascript - 在 Angular js 1.6.2 中使用自定义过滤器

Question

下面的代码片段与 Angular 1.4.2 完美配合，但是在将 Angular js 库升级到 1.6.2 后。

我搜索了迁移/升级文档..等。没有找到解决办法。

HTML 代码:

<input ng-model="query" type="text" name="js_filter" >

作为我的自定义表的一部分，tbItems.rows 将包含一些数组/对象格式的数据

<tr ng-repeat-start="datarow in resultItems = (tbItems.rows | filter:magikFilterQuery ) " >

JavaScript 片段:

myControllers.controller('myContrBasic', ['$scope', '$http',
    function ($scope, $http) {

    $scope.magikFilterQuery = function (item) {
        var term;
        var part;
        if (angular.isUndefined($scope.query) === false) {
          if ($scope.matchcase === true) {
            term = item.data[3];
            part = $scope.query;
          }
          else {
            term = angular.lowercase(item.data[3]);
            part = angular.lowercase($scope.query);
          }
          if (term.indexOf(part) === -1) {
            return false;
          }
          else {
            return true;
          }
        }
        else {
          return true;
        }
      };

升级 Angular js 后出错:

您需要为您的函数 magikFilterQuery 定义一个过滤器，例如

angular.module('myApp').filter('magikFilterQuery', function() {
  return function(item) {
    var term;
    var part;
    if (angular.isUndefined($scope.query) === false) {
      if ($scope.matchcase === true) {
        term = item.data[3];
        part = $scope.query;
      }
      else {
        term = angular.lowercase(item.data[3]);
        part = angular.lowercase($scope.query);
      }
      if (term.indexOf(part) === -1) {
        return false;
      }
      else {
        return true;
      }
    }
    else {
      return true;
    }
  }
});
