Javascript 将Mootools 1.1发送至Mootools 1.2后更新div

我有一个Mootools 1.1脚本，在提交表单后更新div

试图将其转换为mootools 1.2.4，但日志不起作用，我也没有收到任何错误

Mootools 1.1

        $('myform').addEvent('submit', function(e) {

            new Event(e).stop();
            var log = $('log_res').empty().addClass('ajax-loading');
            this.send({
                update: log,
                onComplete: function() {
                    log.removeClass('ajax-loading');

                }
            });
        }); 

mootols 1.2

        $('myform').addEvent('submit', function(e) {

            new Event(e).stop();
            var log = $('log_res').empty().addClass('ajax-loading');
            this.set('send',{
                update: log,
                onComplete: function() {
                    log.removeClass('ajax-loading');

                }
            }).send();
        }); 

试试这个：

     $('myform').addEvent('submit', function(e) {

        e.stop();
        var log = $('log_res').empty().addClass('ajax-loading');
        this.set('send',{
            url: this.get("action"),
            data: this,
            update: log,
            onComplete: function() {
                log.removeClass('ajax-loading');

            }
        }).send();
    });
