在网页上的Jquery上的错误

Question

在我的网页中，我有两个绑定到jquery的控件。 一个是将文本框的值复制到剪贴板的按钮，其他是输入日期的文本框。

但问题是，当我调试这个Web应用程序，它引发了jQuery的错误。 而当我注释掉一个JavaScript方法和调试，它的工作原理（尝试用这两种JavaScript方法）。

但是，当我不注释掉，它不起作用。

.aspx的代码：

     .auto-style1 {

      font-size: large; 
     }

如果我注释掉的JavaScript方法中的任何一个作品..

Answer 1

你包括jQuery的的多个版本，而第二个版本覆盖第一个版本。

因此，任何与第一个版本关联的插件都将被删除。 （在这种情况下为ZClip）

Answer 2

没错。您不能使用相同的jquery插件库（zclip）两次，以将其附加到$符号。如果你真的需要（源代码和缩小代码），你应该为它们中的一个使用不同的变量名称。否则会引起冲突。如果你是在生产环境

  <script src="Scripts/jquery-1.9.1.js" type="text/javascript"></script> 
      <script src="Scripts/jquery.zclip.min.js" type="text/javascript"></script> 
      <script type="text/javascript"> 

       $(document).ready(function() { 
        $('#<%=Button3.ClientID%>').zclip({ 
         path: 'ZeroClipboard.swf', 
         copy: function() { return $('#<%=TextBox2.ClientID%>').val(); } 
       }); 
       }); 
      </script> 

：

所以，我宁愿你使用此代码。如果你在开发环境中，那么你应该使用jQuery插件的未压缩版本文件。
