使用 DropDownListFor 添加 'required' 属性
本文关键字:属性 required DropDownListFor 添加 使用 | 更新日期: 2023-09-27 18:30:39
>我有这个:
@Html.DropDownListFor(x => x.SelectedValue, new SelectList(Model.SomeList, "Value", "Text"))
并希望将其呈现为:
<select required>
<option>...</option>
...
我该怎么做?
使用这个:
@Html.DropDownListFor(x => x.SelectedValue, new SelectList(Model.SomeList, "Value", "Text"), new {required = "required"})
它不会实现速记<select required
但它应该具有相同的效果。虽然我发现你可以使用
@Html.DropDownListFor(x => x.SelectedValue, new SelectList(Model.SomeList, "Value", "Text"), new {required = (string)null})
这有点丑。
VB.NET
@Html.DropDownListFor(Function(Model) Model.ProgramTypeId, New SelectList(Model.allPrograms,
"ProgramTypeId", "ProgramName"), "Select Program....",
New With {Key .class = "form-control", Key .required = "Required"})
尝试以下操作
@Html.DropDownList("PlanType", null, "Select Plan Type", htmlAttributes: new { @class = "form-control", required = "Select Plan Type" })
