Fiddler link

我正在使用Tippy library创建HTML工具提示。我提出了2条指令来处理尖端的工具提示。

.directive('settings', function() {
    return {
      templateUrl: 'tippy-template.html'
    };
  })
  .directive('tippy', function() {
    return function (scope) {
      tippy('.tippy', {
           position: 'bottom',
           animation: 'shift',
           arrow: true,
           interactive: true,
           arrowSize: 'big',
           distance: 20,
           html: document.getElementById('setting-template'),
           appendTo: document.getElementById('settings-controller')
      })
    };
  })


settings指令包含HTML工具提示代码,并且tippy指令将放置在HTML工具提示代码中以将其激活。
Tippy工具与其所在的控制器共享数据,在此示例中,它共享缓存。

如果只有tippy Fiddler 1 controller的一个实例,则一切正常。我无法再次使用该指令。我能够重现我遇到的问题,Fiddler 2 controllers link

javascript - 无法将指令应用于AngularJS中的两个不同的 Controller-LMLPHP
根据我的理解,Tippy仅在有唯一ID时才能使用。有办法解决吗?

tippy-template.html

<div id="setting-template" tippy>
   <ul class="collection">
     <li class="collection-item">
       <div class="col-title"><b>{{title}}</b></div>
       <div class="col-title">Cache</div>
       <div class="col-item">
         <div class="switch">
           <label>Off
                <input ng-model="cache" type="checkbox"><span class="lever"></span> On
           </label>
         </div>
       </div>
     </li>
     <li class="collection-item">
       <div class="col-title"><b>Cache Result</b></div>
       <div class="col-item">{{cache}}</div>
    </li>
  </ul>
</div>


指令用法(在控制器内部)

<div id="settings-controller" settings></div>

最佳答案

在为自己做错的事情绞尽脑汁之后,我终于找到了解决方案。基本上,您需要为类(.tippy)创建一个唯一的ID,并且我基本上直接使用了元素,您说的是document.getElementById()是其工作所必需的,但是$element[0]可以做同样的事情。通过在控制台中记录两个输出来解决这一问题。无论如何,请检查下面的提琴与解决方案。

  .directive('tippy', function() {

  })
  .controller('controller2', function($scope) {
    $scope.title = "Controller 2";
    $scope.cache = true;
  })
  .controller('controller1', function($scope) {
    $scope.title = "Controller 1";
    $scope.cache = false;
  });


我建议您尝试使该指令更通用,更易于使用,并发布Github GIST,以便将来其他人可以轻松使用Tippy
