jquery - 如何获取自动完成文本框值

Question

我正在使用 jquery 自动完成功能。我已将此应用于以特定 id 开头的所有文本框，并根据当前文本框值过滤响应。但不要得到价值。下面是我的代码。

$("input[id^='TextBoxAssociate']").autocomplete(
    {
        source: function (request, response) {
            $.ajax({
                type: "POST",
                contentType: "application/json; charset=utf-8",
                url: "CreateEditRequest.aspx/GetEmpNames",
                data: "{'empName':'" + $(this).val() + "'}", // here $(this) is ajax context, I want value of current textbox
                dataType: "json",
                success: function (data) {
                    response($.map(data.d, function (el) {
                        return {
                            label: el.EmpName,
                            value: el.EmpId
                        };
                    }));
                },
                error: function (result) {
                    alert("Error");
                }
            });
        }

    select: function (event, ui) {
            var label = ui.item.label;
            var value = ui.item.value;
alert('Label : ' + label );
alert('Value : ' + value );
        }
                });
            }
