自动完成HTML中的错误404(使用ASP.NET和JQuery) [英] Auto complete ERROR 404 in HTML (using ASP.NET and JQuery)

问题描述

由于asp.net项目中的某些原因，我的自动完成功能无法正常工作，我尝试了多种方法，除了在数据连接中使用数据源外，其他方法均无济于事.我已经为其创建了一个名为Diagnose的数据库，但是由于某种原因，它在jquery上显示错误404.

For some reason in asp.net project, my autocomplete won't work, I have tried different methods from using Data source in data connection but to no avail. I have already created a database for it called Diagnose but for some reason, it displays error 404 on jquery.

这是我的HTML代码:

<script src="https://ajax.aspnetcdn.com/ajax/jquery/jquery-1.8.0.js"></script>
<script src="https://ajax.aspnetcdn.com/ajax/jquery.ui/1.8.22/jquery-ui.js"></script>
<script>
    $(function () {
        $("#search-diagnosis").autocomplete({
            source: function (request, response) {
                var param = {
                    searchdetails: $('#search-diagnosis').val()
                };
                $.ajax({
                    url: "SearchController.cs/GetSearch",
                    data: JSON.stringify(param),
                    type: "post",
                    contentType: "application/json; charset=utf-8",
                    dataFilter: function (data) { return data; },
                    success: function (data) {
                        response($.map(data.d, function (item) { return { value: item } }))
                    },
                });
            },
            minLength: 1
        });
    });
</script>


<div class="search">
    <input id="search-diagnosis" class="w-75" type="text" placeholder="Start typing your diagnois...">
</div>

这是CS代码:

[WebMethod]
public static List<string> GetSearch(string searchdetails)
{
    List<string> search = new List<string>();
    string mainconn = ConfigurationManager.ConnectionStrings["mybase.database"].ConnectionString;
    SqlConnection sqlconn = new SqlConnection(mainconn);
    string sqlquery = string.Format("select Name from [dbo].[Diagnose] where Name LIKE '%{0}%'", searchdetails);
    sqlconn.Open();
    SqlCommand sqlcomm = new SqlCommand(sqlquery, sqlconn);
    SqlDataReader sdr = sqlcomm.ExecuteReader();
    while (sdr.Read())
    {
        search.Add(sdr.GetString(0));
    }
    sqlconn.Close();
    return search; 
}

它显示错误:

当我打开jquery-1.8.0.js:8214时，向我显示此xhr.send( ( s.hasContent && s.data ) || null );

When I open the jquery-1.8.0.js:8214 it shows me this xhr.send( ( s.hasContent && s.data ) || null );

我在这个问题上停留了一段时间，所以任何帮助都会很大，在此先感谢:D< 3

I'm stuck at this problem for a while so any help would be great, thanks in advance :D <3

推荐答案

它返回404找不到.我认为GetSearch应该在aspx或ascx文件中. Webmethod可在System.Web上下文中使用，并且在某些情况下将需要Page.

It is returning 404 not found. I think that GetSearch should be inside of an aspx or an ascx file. Webmethod works in System.Web context and in some point it will require Page.
