如何获得查看HTML并返回到客户端 [英] How to get view html and return to client side

问题描述

下面是code片段它会返回以jQuery函数，但我想知道我怎么能提取或获取查看HTML并返回到客户端;

below is code snippet which return view to jquery function but i like to know how could i extract or get the view html and return to client end.

$(function() {
   $('#myddl').change(function() {
       var url = $(this).data('url');
       var value = $(this).val();
       $('#result').load(url, { value: value })
    });
});

<div id="result"></div>

和Foo操作里面，你可以返回一个局部视图：

and inside the Foo action you could return a partial view:

public ActionResult Foo(string value)
{
    SomeModel model = ...
    return PartialView(model);
}

在Web表单这样我extarct的用户控件或任何控件相关的HTML。

in web form this way i extarct the usercontrols or any controls related html.

System.Web.UI.Page pageHolder = new System.Web.UI.Page();
BBAReman.facebox.FeedBack ctl = (BBAReman.facebox.FeedBack)pageHolder.LoadControl("~/UserControls/FeedBack.ascx");
System.Web.UI.HtmlControls.HtmlForm tempForm = new System.Web.UI.HtmlControls.HtmlForm();
tempForm.Controls.Add(ctl);
pageHolder.Controls.Add(tempForm);
StringWriter output = new StringWriter();
HttpContext.Current.Server.Execute(pageHolder, output, false);
outputToReturn = output.ToString();

因此​​，如何做同样的MVC中。只是想知道我怎么能获得操作方法的查看HTML。谢谢

so how to do the same in mvc. just like to know how could i get the view html from action method. thanks

推荐答案

您可以使用此方法，从控制器传递的ActionResult，并从视图中取回HTML

You can use this method , passing the ActionResult from controller and getting back html from the view

    private string RenderActionResultToString(ActionResult result)
    {
        // Create memory writer.
        var sb = new StringBuilder();
        var memWriter = new StringWriter(sb);

        // Create fake http context to render the view.
        var fakeResponse = new HttpResponse(memWriter);
        var fakeContext = new HttpContext(System.Web.HttpContext.Current.Request,
            fakeResponse);
        var fakeControllerContext = new ControllerContext(
            new HttpContextWrapper(fakeContext),
            this.ControllerContext.RouteData,
            this.ControllerContext.Controller);
        var oldContext = System.Web.HttpContext.Current;
        System.Web.HttpContext.Current = fakeContext;

        // Render the view.
        result.ExecuteResult(fakeControllerContext);

        // Restore old context.
        System.Web.HttpContext.Current = oldContext;

        // Flush memory and return output.
        memWriter.Flush();
        return sb.ToString();
    }
