自动完成,源链接问题(MVC,Knockout)

标签: jquery asp.net-mvc knockout.js autocomplete

我有自动完成功能。我的搜索方法位于HomeController中,但我想做一些更改。我创建了名为“Vacancy”的api控制器并在那里转移了搜索方法,但我无法使其工作:状态代码:404 Not Found(搜索方法甚至没有启动)。在转移我所做的所有更改后:

在视图中更改了源链接:

data-autocomplete="@Url.Action("Search", "Vacancy")"

更改了搜索方法:

public object Search(string term)
    {
        var vacancyHeaders =
            new UnitOfWork().Repository<Vacancy>()
                            .Get()
                            .Where(v => v.Header.ToLower().Contains(term.ToLower()))
                            .Select(v => new { label = v.Header })
                            .Distinct()
                            .Take(10);
        return vacancyHeaders;
    }

请帮忙,为什么我的搜索方法无法启动? 下面是我没有api控制器的工作代码:

查看:

<form data-bind="submit: search">
        <input data-bind="value: SearchArgument, valueUpdate: 'blur'" data-autocomplete="@Url.Action("Search", "Home")"  class="form-text" name="search" size="32" maxlength="64" placeholder="Search"/>
        <input type="submit" value="search" />
</form>

脚本

 $(":input[data-autocomplete]").each(function() {
                $(this).autocomplete({ source: $(this).attr("data-autocomplete")});

            });

搜索方法

 public ActionResult Search(string term)
    {
        var vacancyHeaders =
            new UnitOfWork().Repository<Vacancy>()
                            .Get()
                            .Where(v => v.Header.ToLower().Contains(term.ToLower()))
                            .Select(v => new { label = v.Header })
                            .Distinct()
                            .Take(10);
        return Json(vacancyHeaders, JsonRequestBehavior.AllowGet);
    }

如果要在Web API中使用自定义方法名称,则需要更改路由配置以允许它。

Custom method names in ASP.NET Web API问题,这里有一个示例,说明如何配置WebApiConfig文件以包含额外的GET方法并支持常规REST方法:

config.Routes.MapHttpRoute("DefaultApiWithId", "Api/{controller}/{id}", new { id = RouteParameter.Optional }, new { id = @"\d+" });
config.Routes.MapHttpRoute("DefaultApiWithAction", "Api/{controller}/{action}");
config.Routes.MapHttpRoute("DefaultApiGet", "Api/{controller}", new { action = "Get" }, new { httpMethod = new HttpMethodConstraint(HttpMethod.Get) });
config.Routes.MapHttpRoute("DefaultApiPost", "Api/{controller}", new { action = "Post" }, new { httpMethod = new HttpMethodConstraint(HttpMethod.Post) });

现在,您可以将搜索方法设为以下内容:

public IQueryable GetAutocompleteResponse(string term = null)
{
    var someStrings = new string[] { "vacancy1", "vacancy2" };

    var model = someStrings.Select(c => new { label = c }).AsQueryable();

    return model;
}

最后,我使用jQueryUI自动完成功能来测试它的代码:

<input type="search" name="searchTerm" data-autocomplete="@Url.Action("GetAutocompleteResponse", "Api/Vacancy")" />
<input type="submit" id="submitForm" value="Search By Name" />


@section scripts
{
    <script>
        var createAutocomplete = function () {
            var self = $(this);
            var options = {
                source: self.attr("data-autocomplete")
            };
            self.autocomplete(options);
        }

        $(document).ready(function () {
            $("input[data-autocomplete]").each(createAutocomplete);
        });
    </script>
}
