Asp.net mvc 2 使用ASP.NETMVC2，Html.DropDownListFor-如何调用select上的JQuery函数？

在我的视图中，我正在使用DropDownListFor：

<%: Html.DropDownListFor(model => model.Type, 
                        new SelectList(ComponentsFactory.GetTypeList().Select(a => new { Name = Regex.Replace(a, @"^.*\.", ""), Value = a }).OrderBy(a => a.Name),
                            "Value", "Name", Model.Type), "Select . . .", null) %> 

我想调用参数为“type”的“GetRequiredFields”作为select上所选项目的值，并使用它更新名为“RequiredFields”的“div”。我该怎么做？我是否需要使用Html.DropDownList for以外的其他内容？

试试这个

$(function(){
   $('#Type').change(function(){GetRequiredFields( $(this).val() );});
});

<%: Html.DropDownListFor(model => model.Type, 
                    new SelectList(ComponentsFactory.GetTypeList().Select(a => new { Name = Regex.Replace(a, @"^.*\.", ""), Value = a }).OrderBy(a => a.Name),
                        "Value", "Name", Model.Type), "Select . . .", new { @onchange = "GetRequiredFields(this);" }) %> 

试试这个

<%: Html.DropDownListFor(model => model.Type, 
                    new SelectList(ComponentsFactory.GetTypeList().Select(a => new { Name = Regex.Replace(a, @"^.*\.", ""), Value = a }).OrderBy(a => a.Name),
                        "Value", "Name", Model.Type), "Select . . .", new { @onchange = "GetRequiredFields(this);" }) %> 

function GetRequiredFields(type) 
{
    var selectedValue = $(type).val();
    ...//do JQuery AJAX stuff
}
