AngularJS多个复选框的疑惑（角度材质）

我试图用相同的ng模型获得多个角度材质复选框。我有两个问题：如何获取默认选中的复选框，以及如何使这些复选框中至少有一个是必需的。我试过用ng-checked，但是我不能通过表单发布值。AngularJS多个复选框的疑惑（角度材质）

HTML

 <label for="inputPassword3" class="col-sm-2 control-label">Školski sat *</label> 
     <div class="col-sm-10" > 
     <span class="col-sm-2" ng-repeat="period in periods"> 
      <md-checkbox ng-model="form.periods[period]" ng-click="toggle(period, selected)"> 
      {{ period }}. sat 
      </md-checkbox> 
     </span>{{selected | json}} 
     </div>

App.js

$scope.periods = [1,2,3,4,5,6,7,8,9,0]; /*broj sati*/ 
     $scope.selected = [2]; 
     $scope.toggle = function (period, list) { 
     var idx = list.indexOf(period); 
     if (idx > -1) { 
      list.splice(idx, 1); 
     } 
     else { 
      list.push(period); 
     } 
     }; 
     $scope.exists = function (period, list) { 
     return list.indexOf(period) > -1; 
     };

请帮助。

其实你ngModel是一个对象，因此要获得所选值负载渲染，你应该做到以下几点：

$scope.model = {}; 
$scope.model.periods = {"2": true};

而且让所有复选框处于选中状态，你应该遍历键，如下图所示：

$scope.save = function() { 
    // Get all checked boxes 
    var checked = Object.keys($scope.model.periods).filter(function(key) { 
    return $scope.model.periods[key]; 
    }); 
    console.log(checked); 
}

看到它工作：

(function() { 
 
    angular 
 
    .module('app', ['ngMaterial']) 
 
    .controller('MainCtrl', MainCtrl); 
 

 
    MainCtrl.$inject = ['$scope']; 
 

 
    function MainCtrl($scope) { 
 
    $scope.model = {}; 
 
    $scope.model.periods = {"2": true}; 
 
    $scope.periods = [1, 2, 3, 4, 5, 6, 7, 8, 9, 0]; /*broj sati*/ 
 

 
    $scope.save = function() { 
 
     // Get all checked boxes 
 
     var checked = Object.keys($scope.model.periods).filter(function(key) { 
 
     return $scope.model.periods[key]; 
 
     }); 
 
     console.log(checked); 
 
    } 
 
    } 
 
})();

我希望它有帮助。
