我的模型如何在asp.net mvc的onclick事件注册@ Html.RadioButtonForSelectList 3.0
public class IndexViewModel
{
public IEnumerable<SelectListItem> TestRadioList { get; set; }
[Required(ErrorMessage = "You must select an option for TestRadio")]
public String TestRadio { get; set; }
[Required(ErrorMessage = "You must select an option for TestRadio2")]
public String TestRadio2 { get; set; }
}
public class aTest
{
public Int32 ID { get; set; }
public String Name { get; set; }
}
我的控制器
public ActionResult Index()
{
List<aTest> list = new List<aTest>();
list.Add(new aTest() { ID = 1, Name = "Yes" });
list.Add(new aTest() { ID = 2, Name = "No" });
list.Add(new aTest() { ID = 3, Name = "Not applicable" });
list.Add(new aTest() { ID = 3, Name = "Muttu" });
SelectList sl = new SelectList(list, "ID", "Name");
var model = new IndexViewModel();
model.TestRadioList = sl;
return View(model);
}
我查看
@using (Html.BeginForm()) {
<div>
@Html.RadioButtonForSelectList(m => m.TestRadio, Model.TestRadioList)
</div>
}
帮手法
public static class HtmlExtensions
{
public static MvcHtmlString RadioButtonForSelectList<TModel, TProperty>(
this HtmlHelper<TModel> htmlHelper,
Expression<Func<TModel, TProperty>> expression,
IEnumerable<SelectListItem> listOfValues)
{
var metaData = ModelMetadata.FromLambdaExpression(expression, htmlHelper.ViewData);
var sb = new StringBuilder();
if (listOfValues != null)
{
// Create a radio button for each item in the list
foreach (SelectListItem item in listOfValues)
{
// Generate an id to be given to the radio button field
var id = string.Format("{0}_{1}", metaData.PropertyName, item.Value);
// Create and populate a radio button using the existing html helpers
var label = htmlHelper.Label(id, HttpUtility.HtmlEncode(item.Text));
var radio = htmlHelper.RadioButtonFor(expression, item.Value, new { id = id }).ToHtmlString();
// Create the html string that will be returned to the client
// e.g. <input data-val="true" data-val-required="You must select an option" id="TestRadio_1" name="TestRadio" type="radio" value="1" /><label for="TestRadio_1">Line1</label>
sb.AppendFormat("<div class=\"RadioButton\">{0}{1}</div>", radio, label);
}
}
return MvcHtmlString.Create(sb.ToString());
}
}
这是我使用的代码...不知道如何给控件一个onclick事件。在助手方法中,我找不到任何合适的htmlattributes参数。根据我的要求。点击列表中的任何一个单选按钮,我需要调用一个参数很少的js函数。我无法做到这一点。 Someonce请帮忙。提前致谢。

谢谢你的回复拉斐尔。我没有使用jonlanceley.blogspot.ch/2011/06/的助手。我已经用助手Method编辑过我的帖子。请看看,让我知道。谢谢 – suman 2012-07-12 10:47:48
