我有一个带有下拉列表的视图,它与视图模型相关联...
视图模型的一个属性:
public int selectDTypeID { get; set; }
视图有一个下拉列表:
Html.DropDownListFor(
model => model.selectDTypeID ,
new SelectList(
new List<Object>{
new { value = 1 , text = "Test1" },
new { value = 2 , text = "Test2" },
new { value = 3 , text = "Test3"}
},
"value",
"text"
)
)
如何在不使用额外参数的情况下获取回帖下拉列表的值...我只是希望能够这样做...
[HttpPost]
public ActionResult ContinueDonation(AddDonationViewModel model)
{
var id = model.selectDTypeID;
}
我可以这样做吗?
答案 0 :(得分:2)
如果您的视图是这样的强类型视图,
@model AddDonationViewModel
@using (Html.BeginForm())
{
@Html.DropDownListFor(
model => model.selectDTypeID ,
new SelectList(
new List<Object>{
new { value = 1 , text = "Test1" },
new { value = 2 , text = "Test2" },
new { value = 3 , text = "Test3"}
},
"value", "text"))
<input type="submit" value="go" />
}
单击“提交”时,HttpPost操作方法中的SelectdTYpeID属性中将显示所选值
[HttpPost]
public ActionResult ContinueDonation(AddDonationViewModel model)
{
var id = model.selectDTypeID; // You have your selected ID here
}
