Jquery UI Autocomplete with Image

问题

I am getting an error in this code. Can anybody help me?

<h4>search:<input type="text" id="name-list" /></h4>
<script type="text/javascript" language="javascript">
$(function () {
        $("#name-list")
    .autocomplete({
        source: function (request, response) {
                $.ajax({
                url: "/Home/Searchuser", type: "POST", dataType: "json",
                data: { searchText: request.term, maxResults: 10 }
            })

            return false;

        },

        minLength: 1

        }).data("autocomplete")._renderItem = function (ul, item) {
        var inner_html = '<a><div class="list_item_container"><div class="image"><img src="' + item.PicLocation + '"></div><div class="label">' + item.label + '</div><div class="description">' + item.DisplayName + '</div></div></a>';
                                 return $("<li></li>")
                                .data("item.autocomplete", item)
                                .append(inner_html)
                                .appendTo(ul);
    };

    });
</script>

The data is receiving correctly from the server. Where have i made mistake?

@ JoeFletch Thanks for your help.

I made these changes to the code and then it worked well. Here are some css i used.

<style type="text/css">
DIV.list_item_container {
height: 90px;
padding: 0px;
    }
    DIV.image {
width:90px;
height: 90px;
float: left;
    }
    DIV.description {
font-style: italic;
font-size: 1.1em;
color: gray;
padding: 5px;
margin: 5px;
    }

#name-list
{
    width: 300px;


    }
</style>

Here is my script

$(document).ready(function () {
        $('#name-list').autocomplete({
            source: function (request, response) {
                $.ajax({
                    url: "/Home/Searchuser",
                    data: { searchText: request.term, maxResults: 10 },
                    dataType: "json",
                    success: function (data) {

                        response($.map(data, function (item) {
                            return {
                                value: item.DisplayName,
                                avatar: item.PicLocation,
                                rep: item.Reputation,
                                selectedId: item.UserUniqueid
                            };
                        }))
                    }
                })
            },
            select: function (event, ui) {

                                 alert(ui.item ? ("You picked '" + ui.item.label)
                                                          : "Nothing selected, input was " + this.value);

                return false;
            }
        }).data("ui-autocomplete")._renderItem = function (ul, item) {
            var inner_html = '<a><div class="list_item_container"><div class="image"><img src="' + item.avatar + '"></div><div class="label"><h3> Reputation:  ' + item.rep + '</h3></div><div class="description">' + item.label + '</div></div></a><hr/>';
            return $("<li></li>")
                    .data("ui-autocomplete-item", item)
                    .append(inner_html)
                    .appendTo(ul);
        };


    });

Thanks @Joe. I updated the answer.

For anyone looking at this again. The code provided by mjmrz is fantastic, but only up to jQuery UI 1.8.

After that .data("autocomplete") needs to be changed to .data("ui-autocomplete") and .data("item.autocomplete", item) needs to be changed to b .data("ui-autocomplete-item", item).

Otherwise, no images. Hope this helps someone else.
