asp.net-mvc - ASP.NET MVC 4：如何在控制器操作中获取选定的下拉值？

Question

我的观点如下。我有两个提交按钮；一为find new car一为find used car。如何获取控制器中选定下拉列表的值？

以及如何找出用户按下了 2 个按钮中的哪一个？

@{
        ViewBag.Title = "Home Page";
    }
    @using (Html.BeginForm("Home", "home"))
    {

        <table>
            <tr>
                <td>
                    <h2>
                        Find New car</h2>
                    <table>
                        <tr>

Answer 1

您应该在控制器内部设置两个操作方法并使用 Html.ActionLink 方法来帮助创建表单。

例子：

public ActionResult FindNewCar(string ddlbrand, string ddlModel, string ddlFuelType, string ddlBudget)
{
     // Do something here.
}

public ActionResult FindUsedCar(string ddlbrand2, string ddlModel2, string ddlFuelType2, ddlCity)
{
     // Do something here.
}

看法

@using (Html.BeginForm("Home", "home"))
{
     @Html.ActionLink(...)
}
