jquery - AngularJS 中未定义 Toastr

Question

我正在做教程，这部分是关于实现登录，这应该给出有关登录成功的气球

angular.module("app").value("mvToastr", toastr);

angular.module("app").factory("mvNotifier", function(mvToastr) {
   return {
      notify: function(msg) {
          mvToastr.success(msg);
          console.log(msg);
       }
    }
});

我明白了，但我有点不明白。所有 .js 文件似乎都已加载。请告诉我问题出在哪里，谢谢。

查看toastr sources看起来像 getOptions() 调用了 jQuery 的 $.extend() 方法。

Toastr 依赖于 jQuery，来自 github 自述文件的第一行:

toastr is a Javascript library for non-blocking notifications. jQuery is required. The goal is to create a simple core library that can be customized and extended.

只需在您的主视图 html 中包含 jquery 即可。

<script src="http://code.jquery.com/jquery-1.11.0.min.js"></script>
