Angular：如何强制重新编译指令？ [英] Angular: How to force recompile directive?

问题描述

HTML：

<div ng-repeat="obj in arr">
   <custom-directive status-stored-in="obj"></custom-directive>
</div>

问题：

我有页面 - 内置了大量的 obj s。这意味着 arr 的值将会改变，代表 obj 的当前页面。但是， status-stored-in =obj部分中的 obj 不会随着更改而刷新。

I have page-turn built in for the large amount of objs. Which means that the value of arr, representing the current page of objs, will change. However, the obj in the status-stored-in="obj" part is not refreshed with the change.

现在我的解决方案是在 customDirective ng-if $ c>，来回闪烁它的值以强制重新编译。还有其他等效的，更简洁的方法来解决这个问题吗？

Right now my solution is to add a ng-if in customDirective, flickering its value back and forth to have it force recompiled. Is there any other equivalent, neater way to deal with this?

自定义的开始指令：

module.directive 'checkbox', (checkboxHooks) ->
  restrict: 'E'
  scope:
    hook: '='
    hookedTo: '='
    statusStoredIn: '='
  templateUrl: 'templates/checkbox.html'
  link: (scope, element, attr) ->

要点是它需要获取一个对象，用于存储选中状态。整个过程可以在这里找到：[咖啡 / js ] 。

The gist is that it needs to get hold of an object, for storing the checked status. The whole of it can be found here: [coffee/js].

推荐答案

在指令链接功能中，您需要观察 status-stored-in for changes然后重新编译它，例如：

Inside your directives link function you need to watch status-stored-in for changes and then recompile it e.g.:

   link: function(scope, element) {
    scope.$watch('statusStoredIn', function() {
      element.html(statusStoredIn);
      $compile(element.contents())(scope);
    });
   }
