jQuery UI 自动完成对象

Question

我正在使用 jQuery 1.11.2 并尝试使用自动完成小部件来解析数据数组。 我必须在阵列中的人，威尔史密斯和威廉达福。 当我在文本字段中输入 Wi 时，我希望看到这两个名称都添加到下拉列表中，但我没有收到任何响应。 这是代码的副本：

<script src="js/jquery/jquery-1.11.2.js"></script>
<script src="js/jquery/jquery-ui.js"></script>
<link rel="stylesheet" href="js/jquery/jquery-ui.css"/>
<link rel="stylesheet" href="js/jquery/jquery-ui.theme.css"/>

<script type="text/javascript">
$(function() {
    var data = [
        {
            "id": 1,
            "first_name": "Will",
            "last_name": "Smith",
            "created_at": "2015-01-27T13:09:20.243Z",
            "updated_at": "2015-01-27T13:09:20.243Z"
        },
        {
            "id": 2,
            "first_name": "Willem",
            "last_name": "Dafoe",
            "created_at": "2015-01-27T13:17:23.479Z",
            "updated_at": "2015-01-27T13:17:23.479Z"
        }
    ];
    // Below is the name of the textfield that will be autocomplete    
    $('#search').autocomplete({
        // This shows the min length of charcters that must be typed before the autocomplete looks for a match.
        minLength: 2,
        // This is the source of the auocomplete suggestions. In this case a list of names from the people controller, in JSON format.
        source:data,
        // This updates the textfield when you move the updown the suggestions list, with your keyboard. In our case it will reflect the same value that you see in the     suggestions which is the person.given_name.
        focus: function(event, ui) {
            $('#search').val(ui.item.first_name);
            return false;
        },
        // Once a value in the drop down list is selected, do the following:
        select: function(event, ui) {
            // place the person.given_name value into the textfield called 'select_origin'...
            $('#search').val(ui.item.first_name);
            // and place the person.id into the hidden textfield called 'link_origin_id'. 
            $('#link_origin_id').val(ui.item.id);
                return false;
        }
    }).data( "ui-autocomplete" )._renderItem = function( ul, item ) {
        return $( "<li></li>" ).data( "ui-autocomplete-item", item ).append( "<a>" + item.first_name + "</a>" ).appendTo( ul );
        // For now which just want to show the person.given_name in the list.                             
    };
});
</script>


Search: <input type="text" id="search" />

代码全部位于本地驱动器上的单个 html 文件夹中。 此时不涉及服务器。 此外，我已经检查了检查元素工具是否有错误，但没有显示任何资源，并且找到并加载了所有资源。

问题是自动完成无法呈现其功能的来源。

您需要根据使用的 JSON 数据设置自动完成的来源，

source: function (request, response) {
           //data :: JSON list defined
           response($.map(data, function (value, key) {
                return {
                    label: value.first_name,
                    value: value.id
                }
            }));
        
    },

而且，我还从代码中删除了.data回调。

工作答案 - 正确过滤。 接受的答案中的过滤不起作用，因为没有针对request.term进行任何检查。

 var mydata = [{"id": 1, "name": "John", "age": 23}, {"id": 2, "name": "Mary", "age": 33}, {"id": 3, "name": "Richard", "age": 53}, {"id": 4, "name": "Ashley", "age": 25}, {"id": 5, "name": "Kyle", "age": 17}, {"id": 6, "name": "Samantha", "age": 29}, {"id": 7, "name": "David", "age": 43}, {"id": 8, "name": "Charles", "age": 27}, {"id": 9, "name": "Elaine", "age": 41}, {"id": 10, "name": "William", "age": 22} ]; $('#myautocomplete').autocomplete({ minLength: 2, source: function (request, response) { response($.map(mydata, function (obj, key) { var name = obj.name.toUpperCase(); if (name.indexOf(request.term.toUpperCase()) != -1) { return { label: obj.name + " (" + obj.age + ")", // Label for Display value: obj.id // Value } } else { return null; } })); }, focus: function(event, ui) { event.preventDefault(); }, // Once a value in the drop down list is selected, do the following: select: function(event, ui) { event.preventDefault(); // place the person.given_name value into the textfield called 'select_origin'... $('#myautocomplete').val(ui.item.label); // ... any other tasks (like setting Hidden Fields) go here... } });

我设法通过以下方式使其出色地工作：

$(document).on('ready',function(){
  $(function() {
    var arrLinks = [
    {% for u in users %}
      {
        nombres: "{{ u.names }} {{u.sur_names}}",
        email: "{{ u.username }}",
        documento: {{ u.identificationNumber }},
        telefono: {{ u.phone }},
        label: '{{ u.names }} {{u.sur_names}} / {{ u.username }} * Doc: {{ u.identificationNumber }} - Cel: {{ u.phone }}'
      },
    {% endfor %}
    ];
    $("input[name=search]").autocomplete({
        source: arrLinks
    }).data("autocomplete")._renderItem = function(ul, item) {
        return $("<li>").data("item.autocomplete", item).append("<a>" + item.nombres + "</a>").appendTo(ul);
    };
  });

});

注意：我使用 symfony，从控制器向用户发送一个对象，并在视图（twig）中创建一个 FOR，我用它为 javascript 对象分配我需要的数据。 在标签中定义要搜索的所有参数非常重要。

演示图像！

 $(document).on('ready',function(){ $(function() { var arrLinks = [ { nombres: "Fernando León", email: "efleon9@gmail.com", documento: 10695846754, telefono: 3208123307, label: 'Fernando León / efleon9@gmail.com * Doc: 10695846754 - Cel: 3208123307' }, { nombres: "Edgar Molina", email: "fleon@fitpal.co", documento: 736282826, telefono: 30087654637, label: 'Edgar Molina / fleon@fitpal.co * Doc: 736282826 - Cel: 30087654637' } ]; $("input[name=search]").autocomplete({ source: arrLinks }).data("ui-autocomplete")._renderItem = function(ul, item) { return $("<li>").data("ui-autocomplete-item", item).append("<a>" + item.nombres + "</a>").appendTo(ul); }; }); });

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script> <script src="https://code.jquery.com/ui/1.12.0/jquery-ui.js"></script> <input type="text" name="search">

这是一个执行自动完成操作的工作示例：

source: function(request, response) {
                if (!request || request.term.length < 2)
                    return;
                var term = request.term.toLowerCase();
                var r = $.grep(
                    myObjectArray,
                    function(v, i) {
                        return (v.Name.toLowerCase().indexOf(term) >= 0);
                    }).map(function(v, i) {
                    return {
                        label: v.Name,
                        value: v.Name,
                        data: v  // in case you need the data from object array
                    }
                });
                response(r);
            }
