JS确认框问题

Question

我有以下javascript代码，显示确认框并更新客户表。它用于存档客户。但点击取消时，JS Alert框有时不会消失？在调用方法之前是否需要等待？可能导致问题的原因是什么？感谢

$(function(){
    $("#archiveme").click(function(){

        var data = { 'cust[]' : []};

        $(":checked").each(function() {
            data['cust[]'].push($(this).val());
        });

        var askthem = confirm("Are you sure want to archive these contacts?");

        if(askthem)
        {
            $.ajax({
                type: "POST",
                url: "ajax/customers-process.php?action=archive",
                data: data,
                cache: false,
                success: function (html) {              
                    updateCustomers(customers, corder)
                }
            });
        }
        else
        {
            updateCustomers(customers, corder)
        }

    return false;
    });
});

评论中提到的整个代码。

function updateCustomers(ct, co) {
    $("#customer-area").hide(200);

    if (ct == "all") {
        var customers = "all";
        $("#all-but").addClass("active");
        $("#arc-but").removeClass("active");
        $("#page-title").html('All Customers').fadeIn();
    }

    else if (ct == "arc") {
        var customers = "arc";
        $("#arc-but").addClass("active");
        $("#all-but").removeClass("active");
        $("#page-title").html('Archived Customers').fadeIn();
    }

    var corder = co;
    var datac = 'type=' + ct + '&order=' + co;
    $("#customer-area").html('<div id="loader"><img src="img/loader.gif"></div>');

    $.ajax({
        type: "GET",
        url: "ajax/customers.php",
        data: datac,
        cache: false,
        success: function (html) {

            $("#customer-area").ajaxComplete(function (event, request) {
                $("#customer-area").html(html).fadeIn(300);

                $(function () {

                    $(".cust-order").click(function () {
                        var corder = $(this).attr("id");
                        updateCustomers(customers, corder);
                    });

                    $(function () {
                        $("#archiveme").click(function () {

                            var data = { 'cust[]': [] };
                            $(":checked").each(function () {
                                data['cust[]'].push($(this).val());
                            });

                            var askthem = confirm("Are you sure want to archive these contacts?");
                            if (askthem) {
                                $.ajax({
                                    type: "POST",
                                    url: "ajax/customers-process.php?action=archive",
                                    data: data,
                                    cache: false,
                                    success: function (html) {
                                        updateCustomers(customers, corder)
                                    }
                                });
                            }
                            else {
                                //close()
                            }
                            return false;
                        })
                    })
                });
            });
        }
    });
