AngularJS Jqlite在没有添加元素之后

标签: javascript angularjs angularjs-directive jqlite

考虑一下这个可运行的例子:为什么在el3之后没有放入el4?如果我调试并打印el3,似乎el4已经消失了。如何将元素放在另一个元素之后,以便它们成为兄弟姐妹?

编辑:在调用.after()之前,我不想追加el3。我只需要两个angular.elements,我想将它们组合成两个兄弟,并在指令元素中追加或替换它们。

angular.module('myModule', []) 


.directive('mydir', [function () {
    return {
        restrict: 'E',
        scope: {},
        template:'<div><b>{{myf.str}}</b>',
        link: function (scope, elem, attrs, ctrl) {
          
          
            var el = angular.element('<b>First </b>');
            var el2 = angular.element('<i>Second</i><br>');
            el.append(el2);
            elem.append(el);
          
          
            var el3 = angular.element('<b>Third </b>');
            var el4 = angular.element('<i>Fourth</i>');
            el3.after(el4);
            elem.append(el3);
          
            
        }
    };
}])

angular.module('myModule', [])


.directive('mydir', [
  function() {
    return {
      restrict: 'E',
      scope: {},
      template: '<div><b>{{myf.str}}</b>',
      link: function(scope, elem, attrs, ctrl) {


        var el = angular.element('<b>First </b>');
        var el2 = angular.element('<i>Second</i><br>');
        el.append(el2);
        elem.append(el);


        var el3 = angular.element('<b>Third </b>');
        var el4 = angular.element('<i>Fourth</i>');

        elem.append(el3);
        elem.after(el4);


      }
    };
