我正在与MVC中的一些代码作斗争，我设法将数据表单控制器传递给Jquery对话框小部件，现在我需要知道如何返回控制器，具体取决于用户是接受还是拒绝了记录。有一个我作为CSV上传到MVC View的记录列表，然后我有一个名为Validate Claims的按钮调用存储过程来验证记录，当点击验证声明时弹出一个对话框，控制器ViewBag的响应通过，我想基于验证响应启用用户接受或拒绝记录，当用户接受记录时，它必须将其保存到db然后移动到下一条记录。我如何在MVC JQuery中执行此操作，请协助。
请参阅下面的代码：
这是我的观看代码

我设法将控制器响应传递给对话框，我正在努力触发循环以返回控制器并完成所有记录。当用户点击Accept Record我想回到控制器，并且可能在某处保存记录（sql）并验证下一条记录等等，我基本上问我如何连接Jquery按钮点击Accept或Reject返回控制器并根据用户选择的按钮运行其他代码。
答案 0 :(得分：0)
您可以通过对控制器操作的ajax调用来执行此操作。
$.ajax({
url: "@Url.Action("YourAction", "YourController")",
data: some_parameters
type: "POST",
success: function(response){ },
error: function(jqXHR, textStatus, errorThrown) { }
});
