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
