如何使用其他自定义指令中的元素标签作为另一个自定义指令的模板

我对angularjs比较陌生。我正在客户端上使用angularjs创建一个Web应用程序。我做了几个自定义指令，希望客户能够自定义每次登录时看到的指令。我试图做的是创建一个字符串，该字符串填充有用户选择的自定义指令标签。用户登录时，此信息将作为cookie值保存并由控制器加载。

这是传递过来的Cookie值（我已经对其进行了硬编码）：

public usersCustoms = `<div class="mdl-grid"> 
                                <div id="firstrow" class="mdl-cell mdl-cell--12-col mdl-cell--8-col-tablet mdl-grid" >
                                    <cit-recap > </cit-recap>
                                    <veh-ar-recap></veh-ar-recap>
                                    <new-models-inv></new-models-inv>
                                    <used-models-inv></used-models-inv>
                                </div>
                                <div id="secondrow" class="mdl-cell mdl-cell--12-col mdl-cell--8-col-tablet mdl-grid">
                                    <deal-recap></deal-recap>
                                    <vehicle-inv></vehicle-inv>
                                    <acct-trend></acct-trend>
                                </div>
                                <div id="thirdrow" class="mdl-cell mdl-cell--12-col mdl-cell--8-col-tablet mdl-grid">
                                    <parts-inv></parts-inv>
                                </div>
                            </div>`;

这是指令，最后一个指令“ usersCustomDirective”是应将其他指令引入的指令。

namespace DashboardDemo {
function citRecap(): ng.IDirective {
    return {
        templateUrl: 'ngDashboardDemo/Views/Directives/citrecap.html',
        restrict: 'AE',
        replace: true,
        controller: DashboardDemo.DashboardController,
        controllerAs: 'dc',
        link: function (scope, elem, attrs) {
        }
    }

}
angular.module('DashboardDemo').directive('citRecap', citRecap);


function vehArRecap(): ng.IDirective {
    return {
        templateUrl: 'ngDashboardDemo/Views/Directives/vehArRecap.html',
        restrict: 'AE',
        replace: true,
        controller: DashboardDemo.DashboardController,
        controllerAs: 'dc',
        link: function (scope, elem, attrs) {
        }
    }

}
angular.module('DashboardDemo').directive('vehArRecap', vehArRecap);

function newModelsInv(): ng.IDirective {
    return {
        templateUrl: 'ngDashboardDemo/Views/Directives/newModelsInv.html',
        restrict: 'AE',
        replace: true,
        controller: DashboardDemo.DashboardController,
        controllerAs: 'dc',
        link: function (scope, elem, attrs) {
        }
    }

}
angular.module('DashboardDemo').directive('newModelsInv', newModelsInv);

function usedModelsInv(): ng.IDirective {
    return {
        templateUrl: 'ngDashboardDemo/Views/Directives/usedModelsInv.html',
        restrict: 'AE',
        replace: true,
        controller: DashboardDemo.DashboardController,
        controllerAs: 'dc',
        link: function (scope, elem, attrs) {
        }
    }

}
angular.module('DashboardDemo').directive('usedModelsInv', usedModelsInv);



function dealRecap(): ng.IDirective {
    return {
        templateUrl: 'ngDashboardDemo/Views/Directives/dealRecap.html',
        restrict: 'AE',
        replace: true,
        controller: DashboardDemo.DashboardController,
        controllerAs: 'dc',
        link: function (scope, elem, attrs) {
        }
    }

}
angular.module('DashboardDemo').directive('dealRecap', dealRecap);


function vehicleInv(): ng.IDirective {
    return {
        templateUrl: 'ngDashboardDemo/Views/Directives/vehicleInv.html',
        restrict: 'AE',
        replace: true,
        controller: DashboardDemo.DashboardController,
        controllerAs: 'dc',
        link: function (scope, elem, attrs) {
        }
    }

}
angular.module('DashboardDemo').directive('vehicleInv', vehicleInv);


function acctTrend(): ng.IDirective {
    return {
        templateUrl: 'ngDashboardDemo/Views/Directives/acctngTrend.html',
        restrict: 'AE',
        replace: true,
        controller: DashboardDemo.DashboardController,
        controllerAs: 'dc',
        link: function (scope, elem, attrs) {
        }
    }

}
angular.module('DashboardDemo').directive('acctTrend', acctTrend);

function partsInv(): ng.IDirective {
    return {
        templateUrl: 'ngDashboardDemo/Views/Directives/partsinv.html',
        restrict: 'AE',
        replace: true,
        controller: DashboardDemo.DashboardController,
        controllerAs: 'dc',
        link: function (scope, elem, attrs) {
        }
    }

}
angular.module('DashboardDemo').directive('partsInv', partsInv);

function usersCustomDirective(): ng.IDirective {
    return {

        link: function (scope, elem, attrs) {
            //elem.html(scope.dc.usersCustoms);
            //console.log(scope.dc.usersCustoms);
            elem.html(scope.userOptions);

        },
        restrict: 'AEC',
        replace: true,
        transclude: true,
        controller: DashboardController,
        controllerAs: 'dc',
        scope: {
            userOptions: '@userOptions'
        },
        //template: scope.userOptions

    }
}
angular.module('DashboardDemo').directive('usersCustomDirective', usersCustomDirective);

}

这是我的视图HTML：

<main class="mdl-color--grey-100">
<users-custom-directive user-options ="{{dc.usersCustoms}}"></users-custom-directive></main>

就像现在写的那样，我假设HTML不会显示，因为html无法识别我的自定义标签。我也尝试在链接函数中使用elem.replaceAll，但是得到了相似的结果。当我在chrome中打开开发人员工具时，在元素下可以看到div和div中的自定义标签，但是，仅呈现div，而未渲染自定义标签。控制台已记录了传入的字符串值。我还尝试将“ usersCustomDirective”更改为此：

function usersCustomDirective(): ng.IDirective {
    return {

        link: function (scope, elem, attrs) {
            //elem.html(scope.dc.usersCustoms);
            //console.log(scope.dc.usersCustoms);
            console.log(scope.userOptions);

        },
        restrict: 'AEC',
        replace: true,
        transclude: true,
        controller: DashboardController,
        controllerAs: 'dc',
        scope: {
            userOptions: '@userOptions'
        },
        template: scope.userOptions

    }
}

而不是在html中不显示任何内容，它显示了我传递过来的文本字符串。
