无法将动态添加的指令编译到页面中

加里

我试图将动态添加的element指令添加到页面中，但是它不起作用，并且在添加的页面中进行编译。这是小插曲代码。代码有什么问题？

        var app = angular.module('myApp', []);
      app.controller("fCtrl",function($scope,$compile){
        $scope.xx = ['x','c','y','z','a'];
        $scope.add = function(){
          var templ = document.getElementById('test').innerHTML;
          templ = templ+'<datan-type content="test1" con="{{xx}}"></datan-type>';
          document.getElementById('test').innerHTML = templ;
          //$compile(document.getElementById('test').innerHTML)($scope);
          alert(document.getElementById('test').innerHTML);
        }
      });

      app.directive('datanType', function ($compile) {
  return { 
    restrict: 'E',
    replace: true,
    link: function (scope, ele, attrs) {
        var testTemplate1 = '<h1 ng-repeat="x in arr">Test{{x}}</h1>';
        var testTemplate2 = '<h1>Test2</h1>';
        var testTemplate3 = '<h1>Test3</h1>';
        var template = '';   
        scope.arr  = eval(attrs.con);
        switch(attrs.content){

                template = testTemplate1;

加里（Gary），这真是让我丧命，所以我把早上的目标定为愚蠢的语法：

将您的控制器代码更改为：

var elementToAdd = angular.element('<datan-type content="test1" con="{{xx}}"></datan-type>');
$compile(elementToAdd)($scope);
document.getElementById('test').appendChild(elementToAdd[0]);
