As far as I understand, the below code should render the paragraph three times with a different index value each time. Instead it's only rendering the last transclusion. What's going on here?
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 accepts a 2nd parameter that receives a clone of the element with the new scope applied. You want to use the clone in this function to put into the dom.
