angularjs - 在 angularjs 指令中哪个函数将首先执行？链接或 Controller ？

Question

我已经浏览过这个链接 https://www.undefinednull.com/2014/07/07/practical-guide-to-prelink-postlink-and-controller-methods-of-angular-directives/ ，他们说链接和 Controller 的执行顺序(从头到尾)是

Controller ，

预链接功能，

后链接功能

但在这里我读到 AngularJS: What is the need of the directive's link function when we already had directive's controller with scope?链接在 Controller 之前执行。我应该相信哪一个？

Answer 1

如果是第一个 link然后 controller不可能 require其他指令，并在 link 中使用他们的 Controller 功能。
看一下来自 documentation 的代码:

var directiveDefinitionObject = {
    controller: function($scope, $element, $attrs, $transclude, otherInjectables) { ... },
    controllerAs: 'stringIdentifier',
    require: 'siblingDirectiveName', // requiring another directive       
    compile: function compile(tElement, tAttrs, transclude) {
      return {
         pre: function preLink(scope, iElement, iAttrs, controller) { ... }, //siblingDirectiveName's controller is available in link function 
         post: function postLink(scope, iElement, iAttrs, controller) { ... }
      }          
    },
  };
  return directiveDefinitionObject;
});

为了支持这一声明，我们可以阅读同一页:

controller

Controller constructor function. The controller is instantiated before the pre-linking phase and can be accessed by other directives (see require attribute). This allows the directives to communicate with each other and augment each other's behavior.
