jquery 中注意同步问题

这几天用的jquery比较多，有遇到jquery中同步问题，记录。

 async: false,

$(".btn-sequence").click(function () {

        var info = $("#BranchCode").val();
        if (info == "") {
            BootstrapDialog.alert('customerID and Customer Branch are request!!!');
            return false;
        }
        var tableNum = $("#Customer_Sequence").find("tr").length;
        var tempBranchId = $("input[name='Customeridbranch']").val();
        $.ajax({
            url: this.href,
            async: false,
            cache: false,
            data: { SequenceNum: tableNum, branchId: tempBranchId },
            success: function (html) {
                $("#Customer_Sequence > tbody:last").append(html);
                return false;
            },
            error: function () {
                BootstrapDialog.alert('not access!!!');
            }
        });
        return false;
    });

如果没有加的话  返回的数据有可能会乱了。

 var Search_Booking_Status = $("#Search_Status_Code");

        $.ajax({
            type: "POST",
            dataType: "json",
            url: "@Url.Action("GetStatusSearch")",
            async: false,
            data: { searchText: "", maxResults: 10 },
            success: function (data) {
                Search_Booking_Status.empty();
                $("<option value=''></option>").appendTo(Search_Booking_Status);
                $.each(data, function (i, n) {
                    $("<option value=" + n.ID + " text=" + n.Status_Code + ">" + n.Status_Code + "</option>").appendTo(Search_Booking_Status);
                });
                Search_Booking_Status.find("option[text='DISP']").attr("selected", true);

                if (statusvalue > 0) {
                    Search_Booking_Status.attr("value", statusvalue);
                }

            }
        });

 这样的话 有可能value 没有传到后台
