为什么Ajax.BeginForm不传递表单值？ [英] Why Ajax.BeginForm does not pass form values?

问题描述

我试图通过展示调用Ajax.BeginForm的局部视图，但我不能接受我的表格值（我需要隐藏输入，BOOKID的值，控制器，例如5）。

I'm trying to show a partial view via calling Ajax.BeginForm, but I can't receive the values of my form(I need to get the value of hidden input, bookId, in controller, e.g 5).

//查看

@using (Ajax.BeginForm("Detail", "Books", new AjaxOptions { HttpMethod = "GET",         UpdateTargetId = "ShowBookDiv" }))
{ 
    <input type="hidden" id="bookId" value="5" />
    <input type="submit" id="sBtn" value="Details"  />
}

//控制器

[HttpGet]
public ActionResult Detail(string bookId)
{                               
    if (Request.IsAjaxRequest())    
    {
        var a = Request["bookId"].ToString();
        // some code to get details
        return PartialView("ShowBooks", details);
    }
    ...
}

当我跟踪code在控制器的BookID为空！

When I trace the code in Controller bookId is null!

推荐答案

我添加了名属性为隐藏字段和它的作品！真奇怪！

I've added the "name" property to hidden field and it works !!! really strange!

 <input type="hidden" name="bookId" id="bookId" value="5" />
