Ajax与ViewComponent [英] Ajax with ViewComponent

问题描述

如何在Asp.Net Core中将AJAX用于ViewComponent?也就是说，调用方法@Component.Invoke ("ComponentName", SomeData);的ViewComponent将涉及取决于SomeData的各种视图，而无需重新启动主视图.

How to use AJAX for ViewComponent in Asp.Net Core? That is calling the method @Component.Invoke ("ComponentName", SomeData); ViewComponent will involve various views depending on SomeData without rebooting the main view.

更新

我的解决方法是:

$(function () {
      $(Container).load('ControllerName/ControllerAction', {
                ArgumentName: ArgumentValue });
                                                 });

控制器:

public IActionResult ControllerAction(string value)
        {
           return ViewComponent("ViewComponent", value);
        }

在以前的版本中，有没有一种方法可以直接将ViewComponent用作AjaxHelpers?

Is there a way to directly use a ViewComponent as AjaxHelpers in previous versions?

推荐答案

您的解决方案是正确的. 从文档中获取:

Your solution is correct. From the docs:

[ViewComponents]不能作为HTTP端点直接访问，它们是从您的代码中调用的(通常是在视图中).视图组件从不处理请求.

[ViewComponents are] not reachable directly as an HTTP endpoint, they're invoked from your code (usually in a view). A view component never handles a request.

虽然视图组件未定义控制器之类的终结点，但您可以轻松地执行返回ViewComponentResult内容的控制器操作.

While view components don't define endpoints like controllers, you can easily implement a controller action that returns the content of a ViewComponentResult.

因此，正如您所建议的，

So as you suggested, a lightweight controller can act as an AJAX proxy to our ViewComponent.

public class MyViewComponentController : Controller 
{
    [HttpGet]
    public IActionResult Get(int id) 
    {
        return ViewComponent("MyViewComponent", new { id });
    }
}
