Angularjs:transclude指令模板

Question

如何在下面的情况下使用包含.目的是在html(partials)文件中使用标记,而不是在模板中定义它(在指令内).

我在这里找到了一个很棒的树指令.(来源)原文:http://jsfiddle.net/n8dPm/

我没有在指令中定义模板,而是尝试使用已转换的内容.我还将Angular更新为1.2.0.rc2.更新:http://jsfiddle.net/aZx7B/2/

得到以下错误

TypeError:对象[object Object]的属性'$ transclude'不是函数

码:

module.directive("tree", function($compile) {
    return {
        restrict: "E",
        transclude: true,
        scope: {family: '='},
        template:       
            '<ul>' + 
                '<li ng-transclude></li>' +
                '<li ng-repeat="child in family.children">' +
                    '<tree family="child"></tree>' +
                '</li>' +
            '</ul>',
        compile: function(tElement, tAttr) {
            var contents = tElement.contents().remove();
            var compiledContents;
            return function(scope, iElement, iAttr) {
                if(!compiledContents) {
                    compiledContents = $compile(contents);
                }
                compiledContents(scope, function(clone, scope) {
                         iElement.append(clone); 
                });
            };
        }
    };
});

<div ng-app="myapp">
    <div ng-controller="TreeCtrl">
        <tree family="family">
            <p>{{ family.name }}</p>
        </tree>
    </div>
</div>

编辑:

根据大卫的建议,做了一些改变.http://jsfiddle.net/aZx7B/3/ 现在,它打印,父.改变,family- > treeFamily虽然没有奏效

您还需要在模板中输出系列的名称:http: //jsfiddle.net/roadprophet/DsvX6/

module.directive("tree", function($compile) {
    return {
        restrict: "E",
        transclude: true,
        scope: {family: '='},
        template:       
            '<ul>' + 
                '<li ng-transclude></li>' +
                '<li ng-repeat="child in family.children">' +
                    '<tree family="child">{{family.name}}</tree>' +
                '</li>' +
            '</ul>',
        compile: function(tElement, tAttr, transclude) {
            var contents = tElement.contents().remove();
            var compiledContents;
            return function(scope, iElement, iAttr) {
                if(!compiledContents) {
                    compiledContents = $compile(contents, transclude);
                }
                compiledContents(scope, function(clone, scope) {
                         iElement.append(clone); 
                });
            };
        }
    };
});

您还可以通过这样做简化:http://jsfiddle.net/roadprophet/DsvX6/2/

<div ng-app="myapp">
    <div ng-controller="TreeCtrl">
        <tree family="treeFamily">           
        </tree>
    </div>
</div>


module.directive("tree", function($compile) {
    return {
        restrict: "E",
        transclude: true,
        scope: {family: '='},
        template:       
            '<ul>' + 
                '<li ng-transclude></li>' +
                '<p>{{ family.name }}</p>' + 
                '<li ng-repeat="child in family.children">' +
                    '<tree family="child"></tree>' +
                '</li>' +
            '</ul>',
        compile: function(tElement, tAttr, transclude) {
            var contents = tElement.contents().remove();
            var compiledContents;
            return function(scope, iElement, iAttr) {
                if(!compiledContents) {
                    compiledContents = $compile(contents, transclude);
                }
                compiledContents(scope, function(clone, scope) {
                         iElement.append(clone); 
                });
            };
        }
    };
});

编辑 相同的问题来源.没有模板传递给内部树指令. http://jsfiddle.net/roadprophet/DsvX6/3/

<div ng-app="myapp">
    <div ng-controller="TreeCtrl">
        <tree family="treeFamily">           
                <p>{{ family.name }}</p>
        </tree>
    </div>
</div>

 template:       
            '<ul>' + 
                '<li ng-transclude></li>' +
                '<li ng-repeat="child in family.children">' +
                    '<tree family="child"><div ng-transclude></div></tree>' +
                '</li>' +
            '</ul>'
