javascript - AngularJS : How can I compile a directive as another directive?

Question

我有可以编译的 Angular 指令

1. <greeting />至<print-greeting />和

2. <print-greeting />至Hello World!

我怎样才能把greeting在我的 HTML 中标记并将其编译为 print-greeting然后最后显示Hello World! ？目前它在变成 print-greeting 后停止。 .

这是我的代码:Plunker .

从上述骗子复制的指令:

greeting指令

// Transforms <greeting /> into <print-greeting />
app.directive("greeting", function ($compile) {
  return {
    restrict: 'E',
      priority: 2,
      compile: function ($templateElement, $templateAttributes) {

      var template = '<print-greeting />';
      $templateElement.replaceWith(template);

      return function LinkingFunction($scope, $element, $attrs) { };
    }
  };
});

print-greeting指令

// Transforms <print-greeting /> into "Hello World!"
app.directive("printGreeting", function ($compile) {
  return {
    restrict: 'E',
    priority: 1,
    compile: function ($templateElement, $templateAttributes) {
      var template = 'Hello World!';
       $templateElement.replaceWith(template);

       return function LinkingFunction($scope, $element, $attrs) { };
     }
  };
});

您正在对已编译的模板进行更改。为了使辅助指令被编译，您需要重新编译:

return function LinkingFunction($scope, $element, $attrs) {
    $compile($element);
};
