Razor is very powerful, but it cannot be refreshed by itself, so it needs to be used with ajax.

This article will give a simple example to implement partial refresh of Razor with ajax.

First, we create an MVC project

Let us create a simple Controller Book

Then add a view to it and add some simple Html code

@{
 ViewBag.Title = "Index";
 Layout = null;
}
<!DOCTYPE html>
<html>
<head>
 <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
 <meta charset="utf-8" />
 <meta name="viewport" content="width=device-width, initial-scale=1.0">
</head>
<body>
 <h2>Index</h2>
 @Html.ActionLink("点击我", "Part","Book");
 <p id="partial" ></p>
 @Scripts.Render("~/bundles/jquery")
 <script type="text/javascript">
  $("a").click(function () {
   $.ajax({
    url: "/Test/Book/Part/1",
    success: function (result) {
     console.log(result);
     $("#partial").html(result);
    },
    error: function (msg) {
     console.log(msg);
    }
   })
   return false;
  });
  
 </script>
</body>
</html>

Copy after login

and gave an id="partial ", when I click @Html.ActionLink, the method in javascript will be triggered, and I will use ajax to access the path /Test/Book/Part/1. After the request is successful, the Html I requested will be constructed in

. This is actually This is the principle of partial refresh

This is the code for Part, and then we also add a view to Part

Part The code can be very simple, and then we start our project

We keep clicking the button "Click me"

The page will keep changing.

It should be noted here that when using AJAX request, the Url must be written completely. For example, my Controller is named Test under the Book folder under Area, and the Action is Part, then the Url is /Test/Book /Part, /Test cannot be missing, otherwise the following error will occur

# As you can see, if the Url is not written in full, the View returned by the Action is actually the wrong path.
