我有一个元素,其整个内容可以被转换。转换是可选的,所以我可以让它的内部部分保留但内部元素被转换。让我们看看它的实际效果:
<h4 class="modal-title" ng-transclude="title">
Are you sure you want to remove this <span ng-transclude="innerType">good</span>
</h4>
在指令定义中我有:
myApp.directive('confirmDeleteModal',function(){
return {
restrict:'E',
transclude: {
title:'?modalTitle',
innerType:'?modalType',
},
templateUrl:'templates/confirm_delete_modal.html',
scope: {
obj:'=info',
},
}
});
HTML代码就是这样:
<confirm-delete-modal info="goodToBeDeleted">
<modal-type>good</modal-type>
</confirm-delete-modal>
当我运行代码时,出现以下错误:[ngTransclude:orphan]
。
我该怎么办? 我正在使用AngularJS v1.5.8

您在模态标题的后备内容中使用另一个指令ng-transclude。但是ng-transclude成为了#34;父母&#34;跨度,并没有提供翻译功能。我建议你修改你的指令并使用方法isSlotFilled来知道标题是否被填充:
directive('confirmDeleteModal',function(){
return {
restrict:'E',
transclude: {
title:'?modalTitle',
innerType:'?modalType',
},
link: function(scope, elem, attrs, ctrl, trfn) {
scope.titleFilled = trfn.isSlotFilled('title');
},
template:'<h4 class="modal-title" ng-transclude="title" ng-if="titleFilled"></h4>' +
'<h4 class="modal-title" ng-if="!titleFilled">Are you sure you want to remove this <span ng-transclude="innerType">good</span></h4>',
scope:{
obj:'=info',
}
}
})
