运行此操作后，视图始终不会基于与ticketnumber相关的sp选择百分比。我试图修改它，但没有任何效果。乐意帮忙：）

这句话

$('#ddl-refund :selected').text(this.CANCELLATION_FEE_PERCENTAGE_STR)

它实际上将当前所选选项的文本设置为

此中的任何值。取消\u费用\u百分比\u STR

。它实际上不会更改所选选项。你可以在行动中看到它

您应该做的是从服务器调用中获取

returncode

值，并在

val（）

方法中传递该值，以将特定选项项设置为所选项

假设您的razor使用此标记呈现下拉列表

<SELECT id="ddl-refund">
  <option value="25">Twenty Five</option>
  <option value="26">Twenty Six</option>
  <option value="28">Twenty Eight</option>
  <option value="29">Twenty Nine</option>

如果

此.returncode

为25或26或28或29，则它将起作用

我不太清楚，当您只想发送单个项目时，为什么要发送数组。但这是另一个需要解决的问题。

您在哪里调用

GetTicketData

方法？在什么事件上？这是httpPost，在View上调用可能是因为您的服务器代码没有返回预期的数据。您是否尝试输入brekapoints并查看结果？我尝试输入GetTicketData方法的返回值，数据返回正确。但我认为，我的观点可能有问题。那么哪个部分不起作用呢？谢谢，我会试试看，但我有个问题，控制器上的sp没有“退款代码”，这就是为什么我按百分比得到它，也许我会用完整的代码更新我的帖子，这样你就可以看到问题出在哪里了。我为其他属性发送了一个数组，不仅是ddl，而且我不会发布其他属性，如lblFlight和其他属性。
