据我了解，下面的代码应该每次使用不同的索引值呈现段落三次。相反，它只是渲染最后一个嵌入。这是怎么回事？
const app = angular.module('app', [])
app.component('test', {
transclude: true,
controller: function($scope, $element, $transclude) {
//The transclusion should appear 3 times right? Since we're appending 3 times?
for(let index of [10, 11, 12]) {
const x = $transclude(Object.assign($scope.$new(true), {index}))
$element.append(x)
}
},
});
angular.bootstrap (document.querySelector('body'), ['app'])<body>
<test>
<p>This is {{index}}</p>
</test>
<script src="https://code.angularjs.org/1.5.8/angular.js"></script>
</body>>$transcludeFn接受第二个参数，该参数接收应用了新作用域的元素克隆。你想在这个函数中使用克隆来放入 dom。您可以在此处阅读有关它的更多信息：http://ng.malsup.com/#!/transclude-function 或此处：https://docs.angularjs.org/api/ng/service/$compile#-controller-
