jquery validate: Uncaught TypeError: f.settings[g].call is not a function

参考： https://stackoverflow.com/questions/8045731/f-settingsg-call-is-not-a-function-with-anything-but-submit-validation

将 jquery.validate 的配置改成：

$("#form1").validate({
            onkeyup: false,
            onfocusout: function (element) { $(element).valid() },
