这里有很多代码供我们查看。你能把问题缩小一点吗？从点击按钮开始。当您使用浏览器的调试器时，它是否调用了预期的功能？浏览器控制台上是否有任何错误？在浏览器的调试器中单步执行该函数，是否所有变量都具有您期望的值？是否发出了AJAX请求？请求是否包含您期望的数据？调试服务器端代码时，是否在该请求中调用了预期的控制器操作？它是否收到预期的数据？基本上，这会在哪里失败？更新是否传递了后端识别需要更新的记录所需的主键？除此之外，请参阅上面的注释-检查浏览器控制台，查看是否显示任何错误。我看到您的ITNumber字段已禁用。通常，禁用的控件不会传递到服务器，这可能不会被绑定。把它改为只读，然后看看结果如何。我找到了解决方案。我必须替换这里的很多代码，让我们看一下。你能把问题缩小一点吗？从点击按钮开始。当您使用浏览器的调试器时，它是否调用了预期的功能？浏览器控制台上是否有任何错误？在浏览器的调试器中单步执行该函数，是否所有变量都具有您期望的值？是否发出了AJAX请求？请求是否包含您期望的数据？调试服务器端代码时，是否在该请求中调用了预期的控制器操作？它是否收到预期的数据？基本上，这会在哪里失败？更新是否传递了后端识别需要更新的记录所需的主键？除此之外，请参阅上面的注释-检查浏览器控制台，查看是否显示任何错误。我看到您的ITNumber字段已禁用。通常，禁用的控件不会传递到服务器，这可能不会被绑定。改为只读，看看效果如何。我找到了解决方案。我必须替换
