如何将Html元素的text / Value从视图传递给控制器 [英] How to pass the text/Value of an Html element from view to controller

问题描述

我想访问控制器中按钮的值，然后将其传递给视图。但是从视图传递到控制器的str的值为null。

I want to access the value of button in controller and then pass it to the view as well. But the value of "str" passed from view to controller is null.

@{
     var str = "Shoes";
  }

      <a href="~/Home/Products_By_Category/@str" target="_parent">
                <input type="button" value="Shoes" class="btn"/>
      </a>

<pre lang="c#">

     public ActionResult Products_By_Category(string s)
     {
           ViewBag.category = s;
           return View();
     }

推荐答案

如下更改按钮

Change your button like below

<input type="button" name="button" value="Shoes" class="btn" />

您还需要将参数更改为 st铃声按钮

Also you need to change the parameter to string button

public ActionResult Products_By_Category(string button)

希望这会有帮助

Hope this helps

始终将控制传递的名称作为参数传递给操作方法

Always pass name of the control pass as parameter in action method

嘿，



有可能这样......

      </a>

< br $> b $ b

确定，这会起作用并帮助你。 :)
