本文实例讲述了jquery实现用户信息修改验证输入方法。分享给大家供大家参考。具体如下：
var realnameflag = 0;var addressflag = 0;var zipflag=0;var cellphoneflag=0;var homephoneflag=0;var oldpasswordflag=1;var newpasswordflag=1;//判断emailfunction check_email(){ $(#showspan).hide(); var email = $.trim($(#email).val());

return ; } var reg = /^[\w-]+(\.[\w-]+)*@[\w-]+(\.[\w-]+)+$/; if (reg.test(email)) { $(#emailmsg).html(); emailflag = 0; return ; } else { $(#emailmsg).html(邮箱格式不正确); emailflag = 1; return ; }}function check_realname(){ $(#showspan).hide();
