另一个简单的指令可以是:

var appModule = angular.module("appModule", []);

appModule.directive("checkList", [function () {
return {
    restrict: "A",
    scope: {
        selectedItemsArray: "=",
        value: "@"
    },
    link: function (scope, elem) {
        scope.$watchCollection("selectedItemsArray", function (newValue) {
            if (_.contains(newValue, scope.value)) {
                elem.prop("checked", true);
            } else {
                elem.prop("checked", false);
            }
        });
        if (_.contains(scope.selectedItemsArray, scope.value)) {
            elem.prop("checked", true);
        }
        elem.on("change", function () {
            if (elem.prop("checked")) {
                if (!_.contains(scope.selectedItemsArray, scope.value)) {
                    scope.$apply(
                        function () {
                            scope.selectedItemsArray.push(scope.value);
                        }
                    );
                }
            } else {
                if (_.contains(scope.selectedItemsArray, scope.value)) {
                    var index = scope.selectedItemsArray.indexOf(scope.value);
                    scope.$apply(
                        function () {
                            scope.selectedItemsArray.splice(index, 1);
                        });
                }
            }
            console.log(scope.selectedItemsArray);
        });
    }
};
}]);

控制器:

appModule.controller("sampleController", ["$scope",
  function ($scope) {
    //#region "Scope Members"
    $scope.sourceArray = [{ id: 1, text: "val1" }, { id: 2, text: "val2" }];
    $scope.selectedItems = ["1"];
    //#endregion
    $scope.selectAll = function () {
      $scope.selectedItems = ["1", "2"];
  };
    $scope.unCheckAll = function () {
      $scope.selectedItems = [];
    };
}]);

而HTML:

<ul class="list-unstyled filter-list">
<li data-ng-repeat="item in sourceArray">
    <div class="checkbox">
        <label>
            <input type="checkbox" check-list selected-items-array="selectedItems" value="{{item.id}}">
            {{item.text}}
        </label>
    </div>
</li>

有一种方法可以通过ng-model-options="{getterSetter: true}"直接处理数组并同时使用ng-model。

诀窍是在ng-model中使用getter/setter函数。通过这种方式，你可以使用一个数组作为你的真实模型，并“伪造”输入模型中的布尔值:

<label ng-repeat="fruitName in ['apple', 'orange', 'pear', 'naartjie']">
  <input
    type="checkbox"
    ng-model="fruitsGetterSetterGenerator(fruitName)"
    ng-model-options="{ getterSetter: true }"
  > {{fruitName}}
</label>

$scope.fruits = ['apple', 'pear']; // pre checked

$scope.fruitsGetterSetterGenerator = function(fruitName){
    return function myGetterSetter(nowHasFruit){
        if (nowHasFruit !== undefined){

            // Setter
            fruitIndex = $scope.fruits.indexOf(fruit);
            didHaveFruit = (fruitIndex !== -1);
            mustAdd = (!didHaveFruit && nowHasFruit);
            mustDel = (didHaveFruit && !nowHasFruit);
            if (mustAdd){
                $scope.fruits.push(fruit);
            }
            if (mustDel){
                $scope.fruits.splice(fruitIndex, 1);
            }
        }
        else {
            // Getter
            return $scope.user.fruits.indexOf(fruit) !== -1;
        }
    }
}

注意:如果你的数组很大，你不应该使用这个方法，因为myGetterSetter会被调用很多次。

要了解更多信息，请参见https://docs.angularjs.org/api/ng/directive/ngModelOptions。

这里有一个快速的可重用的小指令，它似乎可以做你想做的事情。我简单地称之为清单。它在复选框更改时更新数组，并在数组更改时更新复选框。

app.directive('checkList', function() {
  return {
    scope: {
      list: '=checkList',
      value: '@'
    },
    link: function(scope, elem, attrs) {
      var handler = function(setup) {
        var checked = elem.prop('checked');
        var index = scope.list.indexOf(scope.value);

        if (checked && index == -1) {
          if (setup) elem.prop('checked', false);
          else scope.list.push(scope.value);
        } else if (!checked && index != -1) {
          if (setup) elem.prop('checked', true);
          else scope.list.splice(index, 1);
        }
      };

      var setupHandler = handler.bind(null, true);
      var changeHandler = handler.bind(null, false);

      elem.bind('change', function() {
        scope.$apply(changeHandler);
      });
      scope.$watch('list', setupHandler, true);
    }
  };
});

这里有一个控制器和一个显示如何使用它的视图。

<div ng-app="myApp" ng-controller='MainController'>
  <span ng-repeat="fruit in fruits">
    <input type='checkbox' value="{{fruit}}" check-list='checked_fruits'> {{fruit}}<br />
  </span>

  <div>The following fruits are checked: {{checked_fruits | json}}</div>

  <div>Add fruit to the array manually:
    <button ng-repeat="fruit in fruits" ng-click='addFruit(fruit)'>{{fruit}}</button>
  </div>
</div>

app.controller('MainController', function($scope) {
  $scope.fruits = ['apple', 'orange', 'pear', 'naartjie'];
  $scope.checked_fruits = ['apple', 'pear'];
  $scope.addFruit = function(fruit) {
    if ($scope.checked_fruits.indexOf(fruit) != -1) return;
    $scope.checked_fruits.push(fruit);
  };
});

(这些按钮演示了更改数组也会更新复选框。)

最后，这里有一个关于Plunker指令的例子:http://plnkr.co/edit/3YNLsyoG4PIBW6Kj7dRK?p=preview

你可以结合AngularJS和jQuery。例如，您需要定义一个数组$scope。控制器中的Selected = [];

<label ng-repeat="item in items">
    <input type="checkbox" ng-model="selected[$index]" ng-true-value="'{{item}}'">{{item}}
</label>

您可以获得拥有所选项目的数组。使用方法alert(JSON.stringify($scope.selected))，可以检查选中的项。

这里还有另一个解决方案。我的解决方案的好处是:

它不需要任何额外的手表(这可能会影响性能) 它不需要控制器中的任何代码来保持干净 代码仍然有些短 它只需要很少的代码就可以在多个地方重用，因为它只是一个指令

下面是指令:

function ensureArray(o) {
    var lAngular = angular;
    if (lAngular.isArray(o) || o === null || lAngular.isUndefined(o)) {
        return o;
    }
    return [o];
}

function checkboxArraySetDirective() {
    return {
        restrict: 'A',
        require: 'ngModel',
        link: function(scope, element, attrs, ngModel) {
            var name = attrs.checkboxArraySet;

            ngModel.$formatters.push(function(value) {
                return (ensureArray(value) || []).indexOf(name) >= 0;
            });

            ngModel.$parsers.push(function(value) {
                var modelValue = ensureArray(ngModel.$modelValue) || [],
                    oldPos = modelValue.indexOf(name),
                    wasSet = oldPos >= 0;
                if (value) {
                    if (!wasSet) {
                        modelValue = angular.copy(modelValue);
                        modelValue.push(name);
                    }
                } else if (wasSet) {
                    modelValue = angular.copy(modelValue);
                    modelValue.splice(oldPos, 1);
                }
                return modelValue;
            });
        }
    }
}

最后就像这样使用它:

<input ng-repeat="fruit in ['apple', 'banana', '...']" type="checkbox" ng-model="fruits" checkbox-array-set="{{fruit}}" />

这就是全部了。唯一增加的是复选框-数组-set属性。

<input type='checkbox' ng-repeat="fruit in fruits"
  ng-checked="checkedFruits.indexOf(fruit) != -1" ng-click="toggleCheck(fruit)">

.

function SomeCtrl ($scope) {
    $scope.fruits = ["apple, orange, pear, naartjie"];
    $scope.checkedFruits = [];
    $scope.toggleCheck = function (fruit) {
        if ($scope.checkedFruits.indexOf(fruit) === -1) {
            $scope.checkedFruits.push(fruit);
        } else {
            $scope.checkedFruits.splice($scope.checkedFruits.indexOf(fruit), 1);
        }
    };
}
