如何在用户单击Jquery对话框中的按钮后运行控制器操作，代码必须遍历所有记录，以便用户可以接受或拒绝

Question

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根据用户是接受还是拒绝记录返回控制器。我有一个记录列表，我以CSV格式上传到MVC View，然后我有一个名为"验证声明"的按钮，该按钮调用存储过程来验证记录，单击验证声明时会弹出一个对话框，其中来自控制器ViewBag的响应已通过，我想然后根据验证响应使用户能够接受或拒绝记录， 当用户接受记录时，必须将其保存到数据库，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：

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到控制器并浏览所有记录。当用户单击"接受记录"我想返回到控制器时，可能会将记录保存在某个地方（sql）并验证下一条记录等等，我基本上是在问如何连接Jquery按钮单击"接受"或"拒绝"返回到控制器并根据用户选择的按钮运行其他代码。

Answer 1

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) { }
});
