jquery加载部分视图asp.net mvc

Question

我在使用母版页的基本 index.aspx 页面上有一些标题选项卡。

标题选项卡从 viewusercontrol () 正确呈现在索引页上。问题是我试图在没有任何运气的情况下将其他部分视图加载到索引页面中。有人能指出我做错了什么吗？

在母版页上我添加了以下 js 代码：

$(document).ready(function () {
    $('div.headertabs span').click(function () {
        var tabclass = $(this).attr('class')
        var tabid = $(this).children('a').attr('id')
        if (tabclass.indexOf("selected") == -1) {
            $(this).parent().children('.selected').removeClass('selected');
            $(this).addClass('selected');
            switch (tabid) {
                case "dashboard": $('#MainContent').load('<%= Html.RenderAction("ViewDashboard") %>');
                default: $('#MainContent').load('<%= Html.RenderAction("ViewDashboard") %>');
            }
        }
    });
});

HomeController.vb

Function ViewDashboard() As ActionResult
    Return PartialView()
End Function

看看这篇文章：Using jQuery ajax to load a partial view in ASP.NET MVC 2 and then retrieve the input on the server again。

Answer 2

另请参阅：This question 或 this one。我使用这个解决方案（也来自某处）：

public class OfferController : Controller
{
    [HttpPost]
    public JsonResult EditForm(int Id)
    {
        var model = Mapper.Map<Offer, OfferEditModel>(_repo.GetOffer(Id));

        return Json(new { status = "ok", partial = this.RenderPartialViewToString("Edit", model) });
    }
}



public static partial class ControllerExtensions
{
    public static string RenderPartialViewToString(this ControllerBase controller, string partialPath, object model)
    {
        if (string.IsNullOrEmpty(partialPath))
            partialPath = controller.ControllerContext.RouteData.GetRequiredString("action");

        controller.ViewData.Model = model;

        using (StringWriter sw = new StringWriter())
        {
            ViewEngineResult viewResult = ViewEngines.Engines.FindPartialView(controller.ControllerContext, partialPath);
            ViewContext viewContext = new ViewContext(controller.ControllerContext, viewResult.View, controller.ViewData, controller.TempData, sw);
            // copy model state items to the html helper 
            foreach (var item in viewContext.Controller.ViewData.ModelState)
                if (!viewContext.ViewData.ModelState.Keys.Contains(item.Key))
                {
                    viewContext.ViewData.ModelState.Add(item);
                }


            viewResult.View.Render(viewContext, sw);

            return sw.GetStringBuilder().ToString();
        }
    }
}
