js autocomplete输入延迟触发执行事件

需求：延迟查询,autocomplete延迟触发执行事件。当有下一个事件开始时，本次事件中断。目的是为了防止调用服务器过于频繁。

        var timeout = 0;//延时处理
        $("#customerName").autocomplete({
            minLength: 0,
            source: function (request, response) {
                clearTimeout(timeout);
                console.log(timeout);
                var customerName = $("#customerName").val();
                var cutomerToken = $("#cutomerToken").val();
                timeout = setTimeout(function () {
                    console.log("run");
                    $.ajax({
                        url: "api/pmstransaction/getcustomerbybigdata",
                        dataType: "json",
                        data: {
                            customerName: customerName,
                            token: cutomerToken
                        },
                        success: function (data) {
                            response(data.Data);
                        }
                    });
                }, 800);
            },
            focus: function (event, ui) {
                $("#customerName").val(ui.item.Name);
                return false;
            },
            select: function (event, ui) {
                module.viewModel.customerInfo.CustomerName(ui.item.Name);
                module.viewModel.customerInfo.CustomerTaxCode(ui.item.TaxCode);
                module.viewModel.customerInfo.CustomerAddressPhone(ui.item.AddressPhone);
                module.viewModel.customerInfo.CustomerBankAccount(ui.item.BankAccount);
);
                return false;
            }
        }).autocomplete("instance")._renderItem = function (ul, item) {
            return $("<li>")
                .append("<div>" + item.Name + "</div>")
                .appendTo(ul);
        }
