求Asp.net Core中Ajax Helper标签的官方文档链接

Hey, I get where you're coming from—moving from ASP.NET MVC's @Ajax.Form and AjaxOptions to ASP.NET Core can feel like you're missing a familiar tool, especially when you can't track down official docs for those old helper tags.

First off, let's clarify: those server-side Ajax Helper tags don't exist natively in ASP.NET Core. Microsoft shifted focus in Core to encourage using native front-end techniques or lightweight libraries instead of relying on server-generated helper code for AJAX functionality.

The jQuery Unobtrusive Ajax approach you found is actually the go-to replacement for that old MVC Ajax Helper behavior, and it's great you got it working in your project. To recap the key bits in case you need to tweak things later:

• Grab the necessary packages: Install Microsoft.jQuery.Unobtrusive.Ajax via NuGet, or include the jQuery and unobtrusive ajax script files directly in your project.
• Configure forms with data attributes: Replace the old AjaxOptions with data-* attributes on your form elements, like this:

  <form asp-action="SubmitForm" asp-controller="Home" 
        data-ajax="true" 
        data-ajax-method="POST" 
        data-ajax-update="#formResult" 
        data-ajax-failure="handleFailure">
      <!-- Form fields go here -->
      <button type="submit">Send</button>
  </form>
  <div id="formResult"></div>
  

• Set up callback functions: Define JavaScript functions to handle success, failure, or other events, for example:

  function handleFailure(xhr, status, error) {
      console.error("Request failed:", error);
      // Add your user-facing error message here
  }
  

Now, about the official docs you're hunting for: There's no dedicated "ASP.NET Core Ajax Helper" doc page because those helpers were removed. Instead, Microsoft's official docs cover jQuery Unobtrusive Ajax indirectly in sections about form handling and client-side script integration. They also tend to push modern alternatives like the Fetch API or Axios for AJAX calls, since those give you more control without relying on server-side helpers.

If you want to dig deeper into best practices for AJAX in ASP.NET Core, check out the official docs on client-side development and form submission optimization—those will cover similar use cases you're used to with the old helpers.
