javascript - jQuery UI 自动完成对象

Question

我正在使用 jQuery 1.11.2 并尝试让自动完成小部件解析数据数组。我必须要在阵列中的人，Will Smith 和 Willem Dafoe。当我在文本字段中输入 Wi 时，我希望看到这两个名称都被添加到下拉列表中，但我没有得到任何回应。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" />

所有代码都在本地驱动器上的单个 html 文件夹中。此时不涉及任何服务器。此外，我检查了检查元素工具是否有错误，但没有显示任何错误，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。

您需要根据存在的 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。
