注册功能
1.分析
！！因为页面是html格式的，为保证数据传输，请求采用ajax发送
2.代码实现
前端
表单验证
<script>
function checkUsername(){
var username = $("#username");
var regexp = /^\w{8,20}$/;
var flag = regexp.test(username.val());
if(flag){
username.css("border","");
}else{
username.css("border","1px solid red");
}
return flag;
}
function checkPassword(){
var password = $("#password");
var regexp = /^\w{8,20}$/;
var flag = regexp.test(password.val());
if(flag){
password.css("border","");
}else{
password.css("border","1px solid red");
}
return flag;
}
function checkEmail(){
var email = $("#email");
var regexp = /^\w+@\w+\.\w+$/;
var flag = regexp.test(email.val());
if(flag){
email.css("border","");
}else{
email.css("border","1px solid red");
}
return flag;
}
function checkName(){
var name = $("#name");
var flag = name.val().length != 0;
if(flag){
name.css("border","");
}else{
name.css("border","1px solid red");
}
return flag;
}
function checkTelephone(){
var telephone = $("#telephone");
var regexp = /^1+\d{10}$/;
var flag = regexp.test(telephone.val());
if(flag){
telephone.css("border","");
}else{
telephone.css("border","1px solid red");
}
return flag;
}
function checkBirthday(){
var birthday = $("#birthday");
var flag = birthday.val().length != 0;
if(flag){
birthday.css("border","");
}else{
birthday.css("border","1px solid red");
}
return flag;
}
function checkCode() {
var check = $("#check");
var flag = check.val().length != 0;
if(flag){
check.css("border","");
}else{
check.css("border","1px solid red");
}
return flag;
}
页面加载完成之后，发送ajax请求，完成注册
$(function(){
$("#registerForm").submit(function(){
if(checkUsername() && checkPassword() && checkEmail() && checkName()
&& checkTelephone() && checkBirthday() && checkCode()){
$.post("user/register",$(this).serialize(),function(data){
if(data.flag){
location.href = "register_ok.html";
}else{
$("#errorMsg").html(data.errorMsg);
}
});
}else{
alert("请填写完整");
}
return false;
});
$("#username").blur(checkUsername);
$("#password").blur(checkPassword);
$("#email").blur(checkEmail);
$("#name").blur(checkName);
$("#telephone").blur(checkTelephone);
$("#birthday").blur(checkBirthday);
$("#check").blur(checkCode);
});
后端

String checkcode = (String)session.getAttribute("CHECKCODE_SERVER");

session.removeAttribute("CHECKCODE_SERVER");

User user = new User();
try {
BeanUtils.populate(user,map);
} catch (IllegalAccessException e) {

}
flag = userService.register(user);
info.setFlag(flag);
if(!flag){
info.setErrorMsg("注册失败");
}
}else{
info.setFlag(flag);
info.setErrorMsg("验证码错误");
}
ObjectMapper jackson = new ObjectMapper();
String infostr = jackson.writeValueAsString(info);
resp.setContentType("application/json;charset=utf-8");
resp.getWriter().write(infostr);
//jackson.writeValue(resp.getWriter(),info);
