ReferenceError：未定義主干-嘗試使用Parse.com Javascript SDK

Question

我正在嘗試為學校項目構建網站，iOS應用程序和Android應用程序，這需要我擁有服務器。 我決定使用Parse，因為它是免費的，並且已將其用於iOS應用程序。 雖然，我沒有Parse Javascript SDK的經驗。

問題：
我已經在index.html文件中鏈接了所有必需的庫，但是當我啟動網站時，出現以下錯誤：

ReferenceError：未定義主干。

題：
是什么導致此錯誤？ 我該如何解決？

從我看過的內容來看，SDK是建立在Backbone.js之上的，並且我必須鏈接Underscore.js，因為Backbone.js依賴於它？

index.html

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="utf-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">

  <!-- Include all compiled plugins (below), or include individual files as needed -->
  <script src="./bootstrap-3.3.5/js/bootstrap.min.js"></script>
</body>

</html>

database.js

  Parse.initialize("X", "X");

  var Student = Backbone.Model.extend({

  });

  var StudentList = Backbone.Collection.extend({
    model: Student
  });

  var StudentListController = Backbone.View.extend({

    initialize: function() {
    }
  });

編輯：

如果我鏈接bone.js，則會出現以下錯誤：

[Error] TypeError: undefined is not an object (evaluating 'i.extend')
    (anonymous function) (backbone-min.js, line 1)
[Error] ReferenceError: Can't find variable: Backbone
    global code (database.js, line 3)

看起來您尚未鏈接您的backbone.js文件

<script src="/path/to/backbone.js"></script>

或鏈接到CDN

<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/backbone.js/1.2.2/backbone-min.js"></script>
<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/backbone.js/1.2.2/backbone-min.map"></script>
<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/backbone.js/1.2.2/backbone.js"></script>
