jqueryui自动完成呈现服务器返回的HTML [英] jqueryui autocomplete render HTML returned by server

问题描述

我有一个带有输入文本框的简单页面.该文本框绑定到对服务器进行AJAX调用的jQuery ui自动完成功能.我的服务器端代码是一个ASP.NET MVC站点. 与在Internet上找到的大多数示例相比，我唯一的区别是服务器端代码返回PartialView(html代码)作为结果而不是JSON .我看到正在发生AJAX调用，并且在AJAX成功事件中也看到了HTML响应.

I have a simple page with an input text-box. The text box is bound to jquery ui autocomplete that makes an AJAX call to the server. My server side code is an ASP.NET MVC site. The only difference I have as compared to most examples found over the Internet is that my Server side code returns a PartialView (html code) as results instead of JSON. I see the AJAX call happening and I see the HTML response in the AJAX success event as well.

我的问题是如何绑定此HTML数据以显示在自动完成"中?

到目前为止，我的代码是:

The code I have so far is:

$(#quick_search_text").autocomplete({ minLength:3， html:是的， autoFocus:是的， 来源:功能(请求，响应){

$("#quick_search_text").autocomplete({ minLength: 3, html: true, autoFocus: true, source: function (request, response) {

            $.ajax({
                type: "POST",
                url: "serversideurl",
                data: "{ 'SearchTerm': '" + request.term + "', 'SearchCategory': '" + $("#quick_search_category").val() + "' }",
                contentType: "application/json; charset=utf-8",
                dataType: "html",
                error: function (jqXHR, textStatus, errorThrown) {
                    console.log(jqXHR);
                },
                success: function (data) {
                  //THIS IS WHERE MY HTML IS RETURNED FROM SERVER SIDE
                  //HOW DO I BIND THIS TO JQUERY UI AUTOCOMPLETE   
                }
            });
        },
        select: function (event, ui) {
        },
        response: function (event, ui) {
            console.log(ui);
            console.log(event);
        }
    });

推荐答案

这有效: 1)在您的控制器中创建一个动作，并将RouteConfig设置为开始该动作

This works: 1) Create an action in your controller and set the RouteConfig to start this action

public class HomeController : Controller
{
    public ActionResult Index20()
    {
        MyViewModel m = new MyViewModel();
        return View(m);
    }

创建没有任何类型母版页的视图

Create a view without any type of master page

添加此视图模型:

public class MyViewModel
{
    public string SourceCaseNumber { get; set; }
}

将添加的HtmlHelpers.cs的命名空间更改为System.Web.Mvc.Html并重建

Change the namespace for the added HtmlHelpers.cs to System.Web.Mvc.Html and rebuild

添加此类:

public class CasesNorm
{
    public string SCN { get; set; }
}

将以下方法添加到您的控制器中:

Add these methods to your controller:

private List<Autocomplete> _AutocompleteSourceCaseNumber(string query)
    {
        List<Autocomplete> sourceCaseNumbers = new List<Autocomplete>();
        try
        {
            //You will goto your Database for CasesNorm, but if will doit shorthand here

            //var results = db.CasesNorms.Where(p => p.SourceCaseNumber.Contains(query)).
            //    GroupBy(item => new { SCN = item.SourceCaseNumber }).
            //    Select(group => new { SCN = group.Key.SCN }).
            //    OrderBy(item => item.SCN).
            //    Take(10).ToList();   //take 10 is important

            CasesNorm c1 = new CasesNorm { SCN = "11111111"};
            CasesNorm c2 = new CasesNorm { SCN = "22222222"};
            IList<CasesNorm> aList = new List<CasesNorm>();
            aList.Add(c1);
            aList.Add(c2);
            var results = aList;

            foreach (var r in results)
            {
                // create objects
                Autocomplete sourceCaseNumber = new Autocomplete();

                sourceCaseNumber.Name = string.Format("{0}", r.SCN);
                sourceCaseNumber.Id = Int32.Parse(r.SCN);
                sourceCaseNumbers.Add(sourceCaseNumber);
            }
        }
        catch (EntityCommandExecutionException eceex)
        {
            if (eceex.InnerException != null)
            {
                throw eceex.InnerException;
            }
            throw;
        }
        catch
        {
            throw;
        }
        return sourceCaseNumbers;
    }

    public ActionResult AutocompleteSourceCaseNumber(string query)
    {
        return Json(_AutocompleteSourceCaseNumber(query), JsonRequestBehavior.AllowGet);
    }
