    function check(f){

语法都错了，js和java混用了

        function check(f) {
            var pwd = f.upass.value;
            var acpwd = f.acupass.value;
            var vc = f.yanzheng.value;
            var vcode = f.img.value;
            var ret = true;///js没有boolean关键字
            if (pwd != acpwd) {
                alert("两次密码不相同！！！");
                ret = false;
                window.location.reload;
            } else if (vcode != vc)/*)这里多了个反括号*/ {
                alert("验证码不对！！！");
                ret = false;
                window.location.reload;
            } else {
                document.forms[0].submit();
            }
            return ret;
        }
