这是我的html

触发元件
还有我的无限滚动指令和应用程序模块

谢谢,对不起,我是angular的新手。

您应该在angular之前加载jQuery,我还使用了较新版本的Massy(3.1.2),因为imagesloaded似乎依赖于较新版本:

<script src="//code.jquery.com/jquery-2.1.0.min.js"></script>
<script src="//cdnjs.cloudflare.com/ajax/libs/masonry/3.1.2/masonry.pkgd.min.js"></script>
<script src="//desandro.github.io/imagesloaded/imagesloaded.pkgd.min.js"></script>
<script src="//code.angularjs.org/1.2.13/angular.js"></script>

非常感谢,这工作做得很好。但有一个问题是,为什么jQuery在前面。Angular不依赖于jQuery,对吗?我更新了答案。Angular不依赖于jqeury,但jqLite可以被jQuery覆盖,当您使用jQuery插件时,您可能需要它。太棒了,我正在使用Angular Sotox和Angular masonty获得相同的示例,我将Angular移动到了jQuery下面,这个示例也很好。这就解释了为什么会这样。再次感谢。谢谢你的回答,我认为angular Massey项目应该更清楚地列出依赖项,因为它只是说加载js文件,但没有关于包含Massey本身或jQuery的信息
function bindJQuery() {
  // bind to jQuery if present;
  jQuery = window.jQuery;
  // reset to jQuery or default to us.

      scope: JQLitePrototype.scope,

  } else {
    jqLite = JQLite;

  angular.element = jqLite;
