我想创建一个包装 md-tabs 的指令，但我收到一个错误，“Orphan ngTransclude Directive”。我已经复制了这个片段中的错误:
angular.module('transcludeExample', ['ngMaterial'])
.directive('worksGreat', function(){
return {
restrict: 'E',
transclude: true,
template: '<ng-transclude></ng-transclude>'
};
})
.directive('doesntWork', function(){
return {
restrict: 'E',
transclude: true,
template: '' +
'<md-tabs md-dynamic-height>' +
'<md-tab label=\'tab 1\'>' +
'<ng-transclude></ng-transclude>' +
'</md-tab>' +
'</md-tabs>'
};

<h3>ng-transclude in a directive works great:</h3>
<works-great>Inner text</works-great>
<hr/>
<h3>md-tabs without a directive works great:</h3>
<md-tabs md-dynamic-height>
<md-tab label="tab 1">
Inner text
</md-tab>
</md-tabs>
<hr/>
<h3>combining md-tabs with a directive doesn't work:</h3>

</html>我找到了 this answer进入手动操作模板之外的元素，但我希望有一种更清晰的“更有 Angular ”的方式。这里发生了什么？有没有一种方法可以定义 ng-transclude 应该应用于什么指令？
最佳答案
This comment on github提出解决方案。 ng-transclude 被设计为通用的，因此它可以与任何指令一起使用，但在这种情况下，这就是问题所在。幸运的是，模仿起来非常简单，我们可以使用 require 指定它应该应用于哪个父级。
我已经用有效的解决方案更新了我的代码片段:
var orphanDemoCtrl = function($transclude){
this.$transclude = $transclude;
}
angular.module('transcludeExample', ['ngMaterial'])
.controller('orphanDemoCtrl', orphanDemoCtrl)
.directive('orphanDemo', function(){
return {
restrict: 'E',
transclude: true,
template: '' +
'<md-tabs md-dynamic-height>' +
'<md-tab label=\'tab 1\'>' +
'<orphan-demo-transclude></orphan-demo-transclude>' +
'</md-tab>' +
'</md-tabs>',
controller: orphanDemoCtrl
};
})
.directive('orphanDemoTransclude', function(){
return {
require: "^orphanDemo",
link: function($scope, $element, $attrs, orphanDemoCtrl){
orphanDemoCtrl.$transclude(function(clone) {
$element.empty();
$element.append(clone);
});
}
}
