Javascript rails中的Jquery/coffee脚本500错误

我对Jquery还不熟悉，我正在尝试理解一个rails应用程序。我有一个电子邮件表单，您发送发票，收件人可以对发票提出异议，但争议发送表单给出了500个错误

xhr.send( ( s.hasContent && s.data )

及

当我刷新记录操作的页面时，发票显示为有争议，但应该发生的操作（实际发送通知和成功消息）没有发生

这是相关的js.erb文件

jQuery('#dispute_invoice_popup').modal('hide');
jQuery(".alert.alert-success").show().find('span').html("<%= escape_javascript @message %>");
jQuery('.response_to_client').html('<%= escape_javascript render("dispute_history") %>');
jQuery('#show_invoice_container').html('<%= escape_javascript render("show_invoice") %>');

---

正如我所说的，我是Jquery的新手，在这里我真的很茫然，我非常感谢任何帮助或建议。如果您需要任何其他信息，请告诉我。

如果没有适当的缩进，就不可能理解您的Coffeescript代码……您还应该包括收到的500个错误（至少包括stacktrace的前几行）

jQuery('#dispute_invoice_popup').modal('hide');
jQuery(".alert.alert-success").show().find('span').html("<%= escape_javascript @message %>");
jQuery('.response_to_client').html('<%= escape_javascript render("dispute_history") %>');
jQuery('#show_invoice_container').html('<%= escape_javascript render("show_invoice") %>');
