ASP.NET Core和JQuery不引人注目的AJAX无法正常工作 [英] ASP.NET Core and JQuery unobtrusive AJAX not working

问题描述

如果我在.net 4.5中启动一个新项目，然后单击Manage nuget软件包，则搜索ajax，然后单击install以确保ajax不引人注目.然后，我可以进入我的cshtml文件并输入@Ajax.___例如@ Ajax.beginForm

If I start a new project in .net 4.5 and hit manage nuget packages, search for ajax, then hit install for ajax unobtrusive. I can then go into my cshtml file and type @Ajax.___ e.g. @Ajax.beginForm

如果我使用Dot Net Core创建一个新项目...我不能，而是给了我无用的错误:

If I create a new project with Dot Net Core... I cannot, where instead it gives me the useless error:

名称'Ajax'在当前上下文中不存在"

"The name 'Ajax' does not exist in the current context"

我在网上搜索，什么都没找到...

I've searched the web, found nothing...

基本上，我想像在.net中那样用Ajax调用来创建表单

Basically I want to make a Form with an Ajax call as you could do in .net

例如:

"@using (Ajax.BeginForm("EmployeeMaster", "Home", new AjaxOptions { HttpMethod = "POST", UpdateTargetId = "divEmp" })) {"

有人知道我还能尝试什么吗?

Anyone know what else I can try?

在上面，我可以看到Ajax是AjaxHelper类型的对象，它来自System.web.mvc.webviewpage ...因此，也许它永远都不意味着可用于.net core

In the above, I can see that Ajax is a object of type AjaxHelper which comes from System.web.mvc.webviewpage... so maybe its never meant to be available for .net core

推荐答案

虽然Ajax.BeginForm()方法不起作用，但实际的Ajax html却不起作用. C#方法仅有助于生成HTML表单标签.原谅我这些语法是错误的，这是从内存中获取的，但是您知道了

While the Ajax.BeginForm() methods do not work, the actual unobtrusive Ajax html does. The C# methods just help generate the Html form tags. Forgive me in thse syntax is wrong, this is from memory, but you get the idea

@using (Ajax.BeginForm("EmployeeMaster", "Home", new AjaxOptions { HttpMethod = "POST", UpdateTargetId = "divEmp" }))
{
    //form content
}

成为

<form asp-action="EmployeeMaster" asp-controller="Home" method="POST" data-ajax="true" data-ajax-update="divEmp">
    <!-- form content-->
</form>

注意::上述HTML STILL需要使用不引人注目的ajax js文件，以便其正确连接这些data- *属性.这不是ASP.NET Core MVC的一部分

NOTE: The above HTML STILL needs the unobtrusive ajax js files for it to wire up these data-* attributes correctly. This is not a part of ASP.NET Core MVC
