输入框提示自动提示类似百度，淘宝的输入框

1.需要的js和样式（jquery 是必选的）

<script src="${ctx}/js/jquery/jquery-1.7.2.js" type="text/javascript"></script>
<script src="${ctx}/js/jquery/jquery-ui-1.9.2.custom.js" type="text/javascript"></script>
    <script src="${ctx}/js/jquery/jquery.ui.core.js" type="text/javascript"></script>
    <script src="${ctx}/js/jquery/jquery.ui.widget.js" type="text/javascript"></script>
    <script src="${ctx}/js/jquery/jquery.ui.position.js" type="text/javascript"></script>
    <script src="${ctx}/js/jquery/jquery.ui.autocomplete.js" type="text/javascript"></script>
    <link href="${ctx}/js/jquery/css/jquery.ui.autocomplete.css" rel="stylesheet" type="text/css" />

2. js

    $("#pName").autocomplete({
                source: function(request, response ) {
                    $.ajax({
                        url: "${ctx}/xxxx/xxxxx.do",
                        dataType: "json",
                        data:{
                            name: request.term
                        },
                        success: function(data) {
                            response($.map(eval(data), function(item) {
                                return {
                                    uid:item.id,
                                    value:item.person.name+"-"+item.person.mobile
                                }
                            }));
                        }
                    });
                },
                minLength:1,
                select:function(event,ui) {
                    $("#pid").val(ui.item.uid);
                    $("#pName").val(ui.item.value);
                }
            });

3.jsp元素

<tr>
                <td><input type="text" id="pName" value=""/></td>
                <td><input type="hidden" id="pid"></td>
                <td><input type="button"  id="submitProjectPerson" value="添加成员"/></td>
