将值从下拉列表传递到mvc3中的控制器 [英] pass value from dropdown to controller in mvc3

问题描述

我是MVC3的新手，以前从未从事过MVC.因此需要一些帮助.

我的视图中有下拉菜单.我想将下拉值传递给 controller .

我该如何实现?

下面是视图

Hi,

I am new to MVC3 and i have never worked on MVC before. So need some help.

I am having dropdown in my view. I want to pass dropdown value to controller.

How can i achieve it?

Below is the view

<div class="editor-label">
           Car Model:
           <select id="CarModel" name="CarModel">
               <option>Select Category</option>
           </select>
       </div>

由于某些原因，我想使用 select 作为下拉列表，而不是 @ Html.Dropdownlist 或 @ Html.Dropdownlistfor

谁能为我提供解决方案，关于如何将上述下拉列表的值传递给控制器​​?

提前谢谢.

问候，

By some reason, I want to use select as the dropdown list instead of @Html.Dropdownlist or @Html.Dropdownlistfor

Can anyone suggest me the solution for the same, on how to pass value of the above dropdown list to controller?

Thanks in advance.

Regards,

推荐答案

这很简单，在HttpPost或HttpGet注释的操作方法中，参数为CarName.下面是一个示例:

查看:

Its pretty simple, In the HttpPost or HttpGet annotated action method have the parameter as CarName. An example is given below:

View:

@using (Html.BeginForm())
{
    <select id="CarModel" name="CarModel">
        <option>Select Category</option>
        <option value="1">one</option>
        <option value="2">two</option>
        <option value="3">three</option>
        <option value="4">four</option>
    </select>
    
    <br />
    
    <input type="submit" value="Submit" />
}

@if (ViewData["Data"] != null)
{
    <h1>@ViewData["Data"].ToString()</h1>
}

控制器:

Controller:

public ActionResult Dropdown()
{
    return View();
}

[HttpPost]
public ActionResult Dropdown(string CarModel)
{
    ViewData["Data"] = CarModel;
    return View();
}

希望这会有所帮助！
