你必须知道的【闭包】陷阱和案例(3)

                bValid = bValid && checkLength(name, "username", 3, 16);
                bValid = bValid && checkLength(email, "email", 6, 80);
                bValid = bValid && checkLength(password, "password", 5, 16);
                if (bValid) {
                    $.ajax({
                        type: "POST",
                        url: "xxxxx.aspx",
                        data: "name=xxxxx&email=xxxxx&password=xxxx"
                    }).done(function (msg) {
                        alert("Data Saved: " + msg);
                        $(this).dialog("close");
                    });
                }
            },
            Cancel: function () {
                $(this).dialog("close");
            }
        },
        close: function () {
            allFields.val("").removeClass("ui-state-error");
        }
    });
这里用的是JqueryUI的dialog插件。详见： http://jqueryui.com/demos/dialog/#modal-form
