jQuery UI 自动完成对象

问题描述 投票：0回答：5

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" />

代码全部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，我已经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Autocomplete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。

工作答案-正确过滤。接受答案中的过滤不起作用，因为没有针对

request.term
进行检查。

	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...
		}
});

我已经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，从控制器我向用户发送一个对象，在视图（树枝）中我创建了一个 FOR，我用它为 javascript 对象分配我需要的数据。在标签中定义您要搜索的所有参数非常重要。

Demo image!

$(document).on('ready',function(){
      $(function() {
        var arrLinks = [
          {
            nombres: "Fernando León",
            email: "[email protected]",
            documento: 10695846754,
            telefono: 3208123307,
            label: 'Fernando León / [email protected] * Doc: 10695846754 - Cel: 3208123307'
          },
          {
            nombres: "Edgar Molina",
            email: "[email protected]",
            documento: 736282826,
            telefono: 30087654637,
            label: 'Edgar Molina / [email protected] * 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);
        };
      });

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);
            }

//create new array
var array = [];  

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"
    }
];



data.forEach(element => {

            var obj = {

                label:element.first_name + ' ' + element.last_name,
                value:element.id,

            };

            array.push(obj);

        });




//use newly created array as source

$("#search").autocomplete({

    source: array,

 });
