帮助修改一下代码。在用户注册时对手机号11位数字和姓名2-4个汉字进行验证

        function finishregistersubmit(){
            var truefalse = true;
            var Message = '未填写下面内容：\n\n';
            if ($.trim($("#number").val()).length==0) {
                Message += '手机\n';
                truefalse=false;
            }
            var re = /^1[3-9]\d{9}$/i;
            if (!re.test($.trim($("#number").val()))) {
                Message += '手机号不正确\n';
                truefalse=false;
            }
            if ($.trim($("#name").val()).length==0) {
                Message += '姓名\n';
                truefalse=false;
            }
            re = /^[\u4e00-\u9fa5]{2,4}$/i;            
            if (!re.test($.trim($("#name").val()))) {
                Message += '姓名必须为2-4位中文\n';
                truefalse=false;
            }   
            if ($.trim($("#password").val()).length==0) {
                Message += '密码\n';
                truefalse=false;
            }
            if (truefalse) {
                $("#finishregister").val("正在注册…");
                return truefalse;
            } else {
                alert(Message);
                return truefalse;
            }
        }
