Question

我在routeProvider模板中有一个自定义标记，用于调用directive模板。 version属性将由范围填充，然后调用正确的模板。

<hymn ver="before-{{ week }}-{{ day }}"></hymn>

有多个版本的赞美诗基于它的周和日。我期望使用该指令来填充正确的.html部分。 templateUrl未读取变量。

emanuel.directive('hymn', function() {
    var contentUrl;
    return {
        restrict: 'E',
        link: function(scope, element, attrs) {
            // concatenating the directory to the ver attr to select the correct excerpt for the day
            contentUrl = 'content/excerpts/hymn-' + attrs.ver + '.html';
        },
        // passing in contentUrl variable
        templateUrl: contentUrl
    }
});

摘录目录中有多个文件标记为before-1-monday.html，before-2-tuesday.html，...

Answer 1

emanuel.directive('hymn', function() {
   return {
       restrict: 'E',
       link: function(scope, element, attrs) {
           // some ode
       },
       templateUrl: function(elem,attrs) {
           return attrs.templateUrl || 'some/path/default.html'
       }
   }
});

所以你可以通过标记提供templateUrl

<hymn template-url="contentUrl"><hymn>

现在您只需注意使用动态生成的路径填充 contentUrl 属性。

Answer 2

您可以使用ng-include指令。

尝试这样的事情：

emanuel.directive('hymn', function() {
   return {
       restrict: 'E',
       link: function(scope, element, attrs) {
           scope.getContentUrl = function() {
                return 'content/excerpts/hymn-' + attrs.ver + '.html';
           }
       },
       template: '<div ng-include="getContentUrl()"></div>'
   }
});

<强> UPD。用于观看ver属性

emanuel.directive('hymn', function() {
   return {
       restrict: 'E',
       link: function(scope, element, attrs) {
           scope.contentUrl = 'content/excerpts/hymn-' + attrs.ver + '.html';
           attrs.$observe("ver",function(v){
               scope.contentUrl = 'content/excerpts/hymn-' + v + '.html';
           });
       },
       template: '<div ng-include="contentUrl"></div>'
   }
});

感谢@pgregory，我可以使用此指令解决我的问题以进行内联编辑

.directive("superEdit", function($compile){
    return{
        link: function(scope, element, attrs){
            var colName = attrs["superEdit"];
            alert(colName);

            scope.getContentUrl = function() {
                if (colName == 'Something') {
                    return 'app/correction/templates/lov-edit.html';
                }else {
                    return 'app/correction/templates/simple-edit.html';
                }
            }

            var template = '<div ng-include="getContentUrl()"></div>';

            var linkFn = $compile(template);
            var content = linkFn(scope);
            element.append(content);
        }
    }
})

这里不需要自定义指令。只需使用ng-include src属性即可。它已编译，因此您可以将代码放入其中。 See plunker with solution for your issue.

Answer 5

我遇到了同样的问题，我的解决方式与其他问题略有不同。我正在使用棱角1.4.4。

就我而言，我有一个shell模板，可以创建一个CSS Bootstrap面板：

<div class="class-container panel panel-info">
    <div class="panel-heading">
        <h3 class="panel-title">{{title}} </h3>
    </div>
    <div class="panel-body">
        <sp-panel-body panelbodytpl="{{panelbodytpl}}"></sp-panel-body>
    </div>
</div>

我希望根据路线包含面板主体模板。

    angular.module('MyApp')
    .directive('spPanelBody', ['$compile', function($compile){
        return {
            restrict        : 'E',
            scope : true,
            link: function (scope, element, attrs) {
                scope.data = angular.fromJson(scope.data);
                element.append($compile('<ng-include src="\'' + scope.panelbodytpl + '\'"></ng-include>')(scope));
            }
        }
    }]);

当路线为#/students时，我会包含以下模板：

<div class="students-wrapper">
    <div ng-controller="StudentsIndexController as studentCtrl" class="row">
        <div ng-repeat="student in studentCtrl.students" class="col-sm-6 col-md-4 col-lg-3">
            <sp-panel 
            title="{{student.firstName}} {{student.middleName}} {{student.lastName}}"
            panelbodytpl="{{'/student/panel-body.html'}}"
            data="{{student}}"
            ></sp-panel>
        </div>
    </div>
</div>

panel-body.html模板如下：

Date of Birth: {{data.dob * 1000 | date : 'dd MMM yyyy'}}

有人想要去的情况下的示例数据：

var student = {
    'id'            : 1,
    'firstName'     : 'John',
    'middleName'    : '',
    'lastName'      : 'Smith',
    'dob'           : 1130799600,
    'current-class' : 5
}

我对此有一个example。

    })
    .directive('element', function () {
        return {
            restrict: 'E',
            link: function (scope, element, attrs) {

            },
            template: '<div ng-include="contentUrl"></div>'
        }
    })

Angular.js指令动态templateURL
