                           e.stop();
                           this.blur();
                           if(this.retrieve('tip:text'))return false;
                           var form = $('fastbuy-form');
                           form.empty().adopt($(this.form).toQueryString().toFormElements());
                           form.adopt(new Element('input', {name:'isfastbuy',value:1,type:'hidden'}));
                           if(!form.retrieve('events',{})['submit'])return form.submit();
                           form.fireEvent('submit',e);                       });这段代码在火狐上不能用，怎么改啊？

Answer 1

firefox用addEventListener('click' , function(){//....})

Answer 2

addEvent是自己封装的吗？
w3c标准是 element.addEventListener(eventtype,fun,true/false)
ie是
attachEvent("on"+eventtype,fun)
