有一个带有按钮的视图,该按钮具有角度指令ng-disabled,绑定到某些模型属性.复杂的是按钮位于< li>内.标签.

我想要做的是设置模型属性,编译视图,然后根据模型属性的值检查按钮是否正确启用或禁用;但是,当我尝试编译时,列表为空：只有< ul>< / ul>标签.

有没有办法完成我想要做的事情？

这是我的代码：

<div ng-show="group.AreItemsExpanded">
    <div>
        <ul>
            <li ng-repeat="item in group.Items">
                <div>
                    {{item.Name}}
                </div>
                <div>
                    <button id="btn" type="button" ng-click="clickItem(item)" 
                            ng-disabled="!permissions.IsAllowed || !item.IsClickable">
                        Click!
                    </button>
                </div>
            </li>
        </ul>
    </div>
</div>

—————–测试——————

describe('testing view', function(){
    beforeEach(module('groups.templates'));

    var $scope;
    var item;
    var $templateCache;
    var $compile;

    beforeEach(inject(function($rootScope, _$templateCache_, _$compile_){
        $templateCache = _$templateCache_;
        $compile = _$compile_;
        item = {
            Name: 'testitem0',
            IsClickable: false
        };
        $scope = $rootScope.$new();
        $scope.group = {
            Items: [item],
            AreItemsExpanded: true
        };
        $scope.permissions = {IsAllowed: false};
    }));

    describe('testing button', function(){
        it('should be enabled', function(){
            $scope.group.Items[0].IsClickable = true;
            $scope.permissions.IsAllowed = true;
            var html = $templateCache.get('view.html');
            var view = $compile(angular.element(html))($scope);
            expect(view.find('button')[0].disabled).toEqual(false);
        });
        it('should be disabled', function(){
            $scope.group.Items[0].IsClickable = false;
            $scope.permissions.IsAllowed = true;
            var html = $templateCache.get('view.html');
            var view = $compile(angular.element(html))($scope);
            expect(view.find('button')[0].disabled).toEqual(true);
        });
    });
});

最佳答案 发现了问题.所有遗漏的都是声明

$scope.$digest(); 

转让后

var view = $compile(angular.element(html))($scope);
