autocomplete一次返回多个值，并且选定后填到不同的Textbox中

   $(txtTest1).autocomplete({
             source: function (request, response) {
                 $.ajax({
                     url: 'HttpHandler.ashx?todo=getdate&term=' + request.term,
                     dataType: "json",
                     success: function (data) {
                         response($.map(data, function (item) {
                             return {
                                 label: item["TEST1"] + "|" + item["TEST2"],
                                 value: item["TEST1"],
                                 entity: item["TEST1"] + "|" + item["TEST2"] + "|" + item["TEST3"]
                             }
                         }))
                     }

                 })
             }
             , select: function (e, ui) {
                 var entityAry = ui.item.entity.split("|");
                 $(txtTest1).val(entityAry[]);
                 $(txtTest2).val(entityAry[]);
                 $(txtTest3).val(entityAry[]);
             }
             , minLength:
             });
