Question

我对angularjs比较新。我正在客户端使用angularjs创建一个Web应用程序。我已经制作了几个自定义指令，并希望客户能够自定义每次登录时看到的指令。我尝试做的是创建一个字符串，其中填充了用户选择的自定义指令标记。此信息将作为cookie值保存，并在用户登录时由控制器加载。

这是传递的cookie值（我现在硬编码）：

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>`;

以下是最后一条指令的指令＆＃34; usersCustomDirective＆＃34;是应该拉其他指令的那个。

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);

}

以下是该视图的HTML：

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

正如现在所写，html没有显示我假设因为html不能识别我的自定义标签。我也尝试在链接功能中使用elem.replaceAll但得到了类似的结果。当我在chrome中打开开发人员工具时，我在div中看到我的div和我的自定义标签，但是，只有div被渲染，自定义标签不是。控制台记录了传入的字符串值。我还尝试更改＆＃34; usersCustomDirective＆＃34;对此：

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

    }
}

它不会在html中显示任何内容，而是显示我经过的文本字符串。

好的，我想出了我需要做的事情。经过进一步研究，我需要在此过程中包含$ compile。我所做的更改是将$ compile添加到指令函数调用中。然后我为模板分配了scope.userOptions值。我在模板上调用了$ compile和viola angularjs magic。现在很棒。希望这有助于其他人。仅供参考，如果您正在使用打字稿，就像我一样，您会收到错误消息：“IScope类型中不存在属性空白”，您需要创建自己的接口并扩展IScope以包含属性

function usersCustomDirective($compile): ng.IDirective {
    return {

        link: function (scope: IMyScope, elem, attrs) {
            var template = scope.userOptions;
            var linkFn = $compile(template);
            var content = linkFn(scope);
            elem.append(content);

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

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

如何使用其他自定义指令中的元素标记作为另一个自定义指令的模板
