I've spent a while trying to find an elegant solution to this, whilst I have a solution that 'works' it doesn't feel like the easiest or correct way of doing things.
我花了一段时间试图找到一个优雅的解决方案，而我有一个“有效”的解决方案，它感觉不是最简单或正确的方法。
So, my question is...how can I dynamically load directives! For some context, below is how I was hoping I'd be able to get away with it! I've not included the routing or anything but the template loads and I assign the below controller with ng-controller.
所以,我的问题是……如何动态加载指令!在某些情况下，下面是我希望我能侥幸逃脱的方法!除了模板加载之外，我没有包含路由或其他内容，我使用ng-controller分配下面的控制器。
app.js
app.js
angular.module('myApp', [])
.controller('someController', ['$scope', function($scope) {
$scope.directives = ['myDirectiveA', 'myDirectiveB'];
}])
.directive('myDirectiveA', function() {
return {
template: '<p>Directive A, exciting.</p>'
};
})
.directive('myDirectiveB', function() {
return {
template: '<p>Directive B, equally as exciting.</p>'
};
});
template.html
template.html
<div ng-controller="someController">
<div ng-repeat="directive in directives">
<x-directive></x-directive> // Attempt 1
<x-{{directive}}></x-{{directive}}> // Attempt 2
<{{'x-' + directive}}></{{'x-' + directive}}> // Attempt 3
</div>
</div>
Any advice that anyone can offer would be greatly appreciated, excuse me if I'm doing anything obviously stupid this is my first time round with Angular!
任何人能提供的任何建议都将非常感谢，如果我做任何明显愚蠢的事情，请原谅我这是我第一次有棱角!

for explain: you have to $compile your directive when you want to use it in other directive like ngRepeat or other custom directive...
解释:当你想在ngRepeat或其他自定义指令等其他指令中使用时，你需要编译你的指令。

$scope.directives = ['my-directive-a', 'my-directive-b'];

.directive('directive', function ($compile) {
