如何在jquery中使用外部javascript库？

Question

What's wrong in my initialization, when I trying to use external javascript library in jquery and I want to get a custom value from my pages and then manipulate that value by using external javascript plugin and then return back new value(or replace with old value), below is my code: 当我尝试在jquery中使用外部javascript库并且想要从页面中获取自定义值，然后使用外部javascript插件操纵该值，然后返回新值（或替换为旧值）时，初始化有什么问题？，以下是我的代码：

 <html>
  <head>
  <meta charset="utf-8">
  <script src="jquery.js"></script>
  <script src="external-library.js"></script>
  <script>
  var OldValue;
  var NewValue;
  OldValue = $(".raw-Data").html();
  NewValue = new External-function(OldValue);

  $(document).ready(function() {
  $(".result").text(NewValue);
  });
  </script>
  </head>

  <body>
  <div class="raw-Data">1318781876406</div>
  <div class="result"></div>
  </body>
  </html>

When I add my <script> section in my document <head> section like above code all things works correctly and I haven't any problem, But the problem arise when I want to add <script> section in end of document before closing <body> tag because Drupal CMS initializing javascript library in bottom of document. 当添加我<script>部分我的文档中<head>部分像上面的代码中所有的东西正常工作，我没有任何问题，但出现问题时，我想补充<script>关闭前的文件结尾部分<body>标记，因为Drupal CMS正在初始化文档底部的javascript库。

 <html>
  <head>
  <meta charset="utf-8">
  </head>

  <body>
  <div class="raw-Data">1318781876406</div>
  <div class="result"></div>

  <script src="jquery.js"></script>
  <script src="External-Library.js"></script>
  <script>
  var OldValue;
  var NewValue;

  $(document).ready(function() {
  OldValue = $(".raw-Data").html();
  NewValue = new ExternalFunction(OldValue);
  $(".result").text(NewValue);
  });
  </script>
  </body>
  </html>

I want to know what's the correct and compacted method to do this. 我想知道什么是正确的压缩方法。

Thanks for any help or suggestion. 感谢您的帮助或建议。

JS variable names / function cannot contain - sign. JS变量名称/函数不能包含-符号。

the common naming convention used by javascript is camelCase javascript使用的通用命名约定是camelCase

so that New-Value should become newValue and External-Function should change to externalFunction 这样New-Value应该变成newValue而External-Function应该变成externalFunction

see javascript variable naming convention on w3schools for more information : 有关更多信息，请参见w3schools上的javascript变量命名约定：
