C# Jquery/Ajax更新表[ASP.NET核心MVC]
我不确定在使用AJAX Jquery之后如何刷新表数据 我需要帮助。我有一个razor视图，在按钮上单击按钮，我发送带有文本框的post请求，并下拉选择值，然后在控制器中，为toastr传递Json响应状态 下一个控制器返回视图并正确显示烤面包机状态 主要问题是，我不知道如何在toastr响应状态之后用新插入的记录刷新该表 这是我对控制器的看法：C# Jquery/Ajax更新表[ASP.NET核心MVC],c#,jquery,asp.net-core,razor,asp.net-core-mvc,C#,Jquery,Asp.net Core,Razor,Asp.net Core Mvc,我不确定在使用AJAX Jquery之后如何刷新表数据 我需要帮助。我有一个razor视图，在按钮上单击按钮，我发送带有文本框的post请求，并下拉选择值，然后在控制器中，为toastr传递Json响应状态 下一个控制器返回视图并正确显示烤面包机状态 主要问题是，我不知道如何在toastr响应状态之后用新插入的记录刷新该表 这是我对控制器的看法： @using SimplCommerce.WebHost.Models @model dynamic public IActionResult I
