这个插件不错，是用jquery写的。能进行表单验证。我喜欢它的原因是因为
1.他有自带的验证规则
2.你可以自己写验证规则
3.可以通过ajax与后台交互，与后台数据比较。最后返回结果！我在表单中要验证是不是存在这个账号的时候需要与后台进行交互，使用ajax是最好不过的！
使用的方法很简单：我简单说一下“
1.写jsp页面，js文件
2.引入的这个类库，一个是juquery的类库文件，一个是validation的文件-----》http://pan.baidu.com/s/1c04nN5u
3.在jsp页面写类库链接，中引入类库，
给一个demo，我是直接在我的sshdemo中截取出来的，你理解原理就可以了

后台ajax验证是否存在这个账号代码
//验证account是否已存在
public String verifyAccount() throws Exception{
int flag=0;//判断是否已存在用户的标志，默认不存在
String account =tue.getAccount();//用户名 userlist = tdao.listall();
for (int i = 0; i < userlist.size(); i++) {
Tuser ae2= userlist.get(i);
String[] s = new String[1];
s[0]=(ae2.getAccount());
if(s[0].equals(account))
flag=1;
}
if(flag==1)
this.getResponse().getWriter().print(false);//存在就给前台返回一个false
else
this.getResponse().getWriter().print(true);//不存在就给前台返回一个true
return null; }
引入juquery类库，和jquery.validate.js就可以了
