Angular Material md-switch并将一个控制器中的输入搜索到另一个控制器

问题描述

我有一个有效的搜索字段和一组复选框，它们可以在Angular JS 1.5.5中的控制器内部的数据上正常工作.我有一个带有搜索字段的第二个控制器和一些角度开关.我希望开关绑定到复选框，但不知道如何将其从一个控制器绑定到另一个控制器，再加上开关为true/false，但是复选框的true/false值不是true/false，它们是字符串.

I have a working search field and set of checkboxes which properly work on my data inside a controller in Angular JS 1.5.5. I have a 2nd controller with a search field and some angular material switches. I want the switches to bind to the checkboxes, but don't know how to get that to bind from one controller to another, plus the switches are true/false but the true/false values of the checkboxes are not true/false, they are strings.

 .controller('mainController', function($scope, $route, $routeParams, $location, $http) {

           // Data object
           $http({
                method: 'GET',
                url: 'utahgolf.json'
           })
           .success(function (data, status, headers, config) {
                $scope.courses = data;
           })
           .error(function (data, status, headers, config) {
                // something went wrong :(
           });
     // Filter defaults
     $scope.Filter = new Object();
     $scope.Filter.courseType = {
                               'public':'public',
                               'private':'private',

推荐答案

要使用Angular Material，您仍然可以使用ng-true-value和ng-false-value设置过滤器对象.

To work with Angular Material, you can still use the ng-true-value and ng-false-value to set the filter object.

要将两个控制器连接在一起，我建议创建一个返回过滤器设置对象的服务方法.然后，您可以将服务注入到两个控制器中，并将本地范围变量设置为其值.每当一个控制器更改对象时，它将反映在另一控制器中:

To connect the two controllers together I recommend creating a service method that returns the filter settings object. Then you can inject the service into both controllers and set a local scope variable to its value. Anytime one controller changes the object it will reflect in the other controller:

var app = angular.module('app', ['ngMaterial']);

app.controller('mainController', function($scope, filterSettings) {

  $scope.filter = filterSettings; // retrieve settings object from service method and bring into scope    
  $scope.OrderFilter = 'name'; // Default sort order

  // Data object
  $scope.courses = [{
    name: 'Course 1',
    courseType: 'Public',
    region: 'Northern'
  }, {
    name: 'Course 2',
    courseType: 'Public',
    region: 'Northern'
  }, {
    name: 'Course 3',
    courseType: 'Private',
    region: 'Northern'
  }, {
    name: 'Links 4',
    courseType: 'Private',
    region: 'Northern'
  }, {
    name: 'Links 5',
    courseType: 'Private',
    region: 'Northern'
  }, {
    name: 'Links 6',
    courseType: 'Public',
    region: 'Southeastern'
  }, {
    name: 'Links 7',
    courseType: 'Public',
    region: 'Southeastern'
  }, {
    name: 'Links 8',
    courseType: 'Military',
    region: 'Southeastern'
  }, {
    name: 'Course 9',
    courseType: 'Private',
    region: 'Southeastern'
  }, {
    name: 'Course 10',
    courseType: 'Private',
    region: 'Southeastern'
  }];
});

app.controller('secondController', function($scope, filterSettings) {
  $scope.filter = filterSettings; // retrieve settings object from service method and bring into scope
});

app.factory('filterSettings', function() {

  // Filter defaults
  var settings = {};
  settings.searchText = '';
  settings.courseType = {
    'public': 'public',
    'private': 'private',
    'military': 'military',
    'resort': 'resort'
  };
  settings.region = {
    'northern': 'northern',
    'central': 'central',
    'southwestern': 'southwestern',
    'southeastern': 'southeastern'
  };

  return settings;
});

// Global search filter
app.filter('searchFilter', function($filter) {
  return function(items, searchfilter) {
    var isSearchFilterEmpty = true;
    angular.forEach(searchfilter, function(searchstring) {
      if (searchstring != null && searchstring != "") {
        isSearchFilterEmpty = false;
      }
    });
    if (!isSearchFilterEmpty) {
      var result = [];
      angular.forEach(items, function(item) {
        var isFound = false;
        angular.forEach(item, function(term, key) {
          if (term != null && !isFound) {
            term = term.toString();
            term = term.toLowerCase();
            angular.forEach(searchfilter, function(searchstring) {
              searchstring = searchstring.toLowerCase();
              if (searchstring != "" && term.indexOf(searchstring) != -1 && !isFound) {
                result.push(item);
                isFound = true;
              }
            });
          }
        });
      });
      return result;
    } else {
      return items;
    }
  }
