使用 ng-clip 和 ng-show/ng-hide 在鼠标悬停时按钮闪烁

Question

当鼠标悬停在 ng-clip 增强按钮上时，我看到奇怪的闪烁。当鼠标悬停在封闭的 div 上时，我得到了 ng-clip 增强按钮 shown/hid。当用户将鼠标移到按钮上时，它会闪烁。我假设这与 Zeroclipboard 和 Angular 代码之间的事件处理有关？

我也遇到了这个问题。我通过在外部 div 上使用 ng-mouseenter 而不是在内部 div 上使用 ng-mouseover 和 ng-mouseleave 而不是 ng-mouseout 来修复。无闪烁！

所以：

<div ng-app="myapp" ng-mouseenter="isHovering = true">
  <div class="container" ng-controller="myctrl" ng-mouseleave="isHovering = false">

    <div class="page-header">
      <h1>ngClip <small>example</small></h1>
    </div>

    <form>
      <div style="background:red;" class="form-group">
        <label >Copy #1</label>
        <input type="text" class="form-control" placeholder="Enter text to copy" ng-model="copy1">
        <button ng-if="isHovering" class="btn btn-default" clip-copy="copy1">Copy!</button>
      </div>

      <br/><br/><br/>

      <textarea class="form-control" rows="3" placeholder="paste here"></textarea>
    </form>
  </div>
</div>
