以下代码运行良好。突然，“编辑”按钮单击停止工作。当用户用来单击“编辑”按钮时，会执行JSON代码。但它现在无法识别点击。偶然发生了什么事？请协助。

我删除了所有外部JS和CSS文件后测试了代码，它似乎工作正常。
问题很可能是你要回来的JSON数据。也许你对它正在调用的PHP文件做了一些事情，因此JSON对象格式不正确，或者打印了一个PHP警告。 （也可能是PHP配置发生变化的结果）
我建议您尝试在Firefox中使用Firebug插件激活（或等效的）。它将准确显示JSON请求返回的内容，以及请求是否有任何错误。

正如Atli所说，代码看起来很好。我好奇这个$.cookie('UpdateRecordID')，是查询字符串的一部分。如果未设置cookie会发生什么？
你能通过萤火虫验证一个正确的反应吗？
