jQuery 自动完成多个输出 [英] jQuery AutoComplete multiple Output

问题描述

我正在使用 jQuery AutoComplete 根据输入的值从数据库中获取结果.然后，用户将单击搜索按钮，告诉页面搜索该特定条目的详细信息.

我想获得 2 个值，名称 和 标题.我只想向用户显示名称，而页面使用标题作为搜索条件.

例如:当一个人输入Vehicle时，结果将在列表中显示Vehicle1, Vehicle2.
当用户点击Vehicle1时，隐藏的框将是Title的问题，即Bike，例如Vehicle2，会发出带有Car的隐藏框.

我可以让 Name 正确显示在文本框中，但我一生都无法(并且经过 2 天的搜索)将 Title 绑定到一个隐藏的盒子.

JavaScript:

<script type="text/javascript" src="http://code.jquery.com/jquery-1.8.2.js"></script><script type="text/javascript" src="http://code.jquery.com/ui/1.9.0/jquery-ui.js"></script><script type="text/javascript">$(document).ready(function () {$(".tb").自动完成({来源:功能(请求，响应){$.ajax({url: "AutoComplete.asmx/FetchEmailList",数据:{'前缀':'"+ request.term +'}"，数据类型:json"，类型:POST"，contentType: "application/json; charset=utf-8",数据过滤器:函数(数据){返回数据；},成功:功能(数据){响应($.map(data.d，函数(项目){返回 {//值:item.Title，标签:item.Name};}));},错误:函数(XMLHttpRequest，textStatus，errorThrown){警报(文本状态)；}});},最小长度:2});});

ASPX 代码:

<asp:TextBox ID="tbAuto" class="tb" runat="server"></asp:TextBox><asp:TextBox runat="server" ID="tbHidden" class="tb"></asp:TextBox>

代码隐藏:

[WebService(Namespace = "http://tempuri.org/")][WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)][脚本服务]公共类自动完成:System.Web.Services.WebService{[网络方法][ScriptMethod(ResponseFormat = ResponseFormat.Json)]公共列表<员工>FetchEmailList(字符串前缀){var emp = 新员工()；var fetchEmail = emp.GetEmployeeList(前缀).Where(m => m.Name.ToLower().StartsWith(prefix.ToLower()));返回 fetchEmail.ToList();}}

CompletionClass:(请原谅命名)

公共类员工{公共字符串标题{获取；放;}公共字符串名称 { 获取；放;}公共字符串值 { 获取；放;}公共列表<员工>GetEmployeeList(字符串前缀文本){列表<员工>cmpList = new List();SqlConnection db = DataConn.SqlConnection();db.Open();SqlTransaction 事务 = db.BeginTransaction();//var array = new ArrayList();尝试{SqlCommand command = new SqlCommand("Select [something] FROM vwGetDetails WHERE [something_else] LIKE N'%" + prefixText + "%' ORDER BY [thatOther_thing] ASC", db, transaction);使用 (SqlDataReader reader = command.ExecuteReader()){而 (reader.Read()){cmpList.Add(new Employee() { Name = reader["Value1"].ToString(), Title = "Value1_Cat", value = "Value1_Cat"});}}command = new SqlCommand("Select [something] FROM [somewhere] WHERE [thingy] LIKE N'%" + prefixText + "%' ORDER BY [previousThingy] ASC", db, transaction);使用 (SqlDataReader reader = command.ExecuteReader()){而 (reader.Read()){cmpList.Add(new Employee() { Name = reader["Value2"].ToString(), Title = "Value2_Cat", value = "Value2_Cat"});}}交易.提交()；}捕获(SqlException){事务.回滚()；cmpList.Add(new Employee() { Name = "Problem Getting Results.", value = "Error"});//array.Add("问题获取结果.");}如果(cmpList.Count == 0)cmpList.Add(new Employee() { Name = "Nothing to Display.", value = "Info"});//array.Add("没什么可显示的.");//返回数组；返回 cmpList；}}

解决方案

对 JavaScript 的那些修改应该可以解决问题:

<script type="text/javascript" src="http://code.jquery.com/jquery-1.8.2.js"></script><script type="text/javascript" src="http://code.jquery.com/ui/1.9.0/jquery-ui.js"></script><script type="text/javascript">$(document).ready(function () {$('input[name$="tbAuto"]').autocomplete({来源:功能(请求，响应){$.ajax({url: "AutoComplete.asmx/FetchEmailList",数据:{'前缀':'"+ request.term +'}"，数据类型:json"，类型:POST"，contentType: "application/json; charset=utf-8",数据过滤器:函数(数据){返回数据；},成功:功能(数据){响应(数据.d)；},错误:函数(XMLHttpRequest，textStatus，errorThrown){警报(文本状态)；}});},最小长度:2，焦点:功能(事件，用户界面){$('input[name$="tbAuto"]').val(ui.item.Name);返回假；},选择:功能(事件，用户界面){$('input[name$="tbAuto"]').val(ui.item.Name);$('input[name$="tbHidden"]').val(ui.item.Title);返回假；}}).data('autocomplete')._renderItem = function(ul, item) {return $('
').data('item.autocomplete', item).append('' + item.Name + '</a>').appendTo(ul);};});

这里的假设是选择器返回的正是我们正在处理的元素，如果不是，则需要对其进行调整.

I am using jQuery AutoComplete to fetch results from a DataBase based on the value inputted. The user will then click a search button to tell the page to search for that specific entries details.

I want to get 2 values, the Name and Title. I only want to display the Name to the user, while the page uses the Title as a search criteria.

eg: When a person types in Vehicle, the result will display Vehicle1, Vehicle2 in a list.
When the user clicks on Vehicle1, a hidden box will be issues with the Title, which would be Bike, and such as with Vehicle2, which will issue the hidden box with Car.

I can get the Name to show in the text box properly, but I cannot for the life of me (And after 2 days of searching) bind the Title to a hidden box.

JavaScript:

解决方案

Those modifications to your JavaScript should do the trick:

<script type="text/javascript" src="http://code.jquery.com/jquery-1.8.2.js"></script>
<script type="text/javascript" src="http://code.jquery.com/ui/1.9.0/jquery-ui.js"></script>
<script type="text/javascript">
    $(document).ready(function () {
        $('input[name$="tbAuto"]').autocomplete({
            source: function (request, response) {
                $.ajax({
                    url: "AutoComplete.asmx/FetchEmailList",
                    data: "{ 'prefix': '" + request.term + "' }",
                    dataType: "json",
                    type: "POST",
                    contentType: "application/json; charset=utf-8",
                    dataFilter: function (data) { return data; },
                    success: function (data) {
                        response(data.d);
                    },
                    error: function (XMLHttpRequest, textStatus, errorThrown) {
                        alert(textStatus);
                    }
                });
            },
            minLength: 2,
            focus: function(event, ui) {
                $('input[name$="tbAuto"]').val(ui.item.Name);
                return false;
            },
            select: function(event, ui) {
                $('input[name$="tbAuto"]').val(ui.item.Name);
                $('input[name$="tbHidden"]').val(ui.item.Title);
                return false;
            }
        }).data('autocomplete')._renderItem = function(ul, item) {
            return $('<li>').data('item.autocomplete', item).append('<a>' + item.Name + '</a>').appendTo(ul);
        };
    });
</script>

The assumption here is that the selectors returns exactly the element which we are working on, if not they need to be adjusted.
