The validation methods contained in the instance are not comprehensive, and if you don't want it, you can

Introduction of JS file:

<script type= "Text/javascript" src= "Js/jquery-1.11.2.js" ></script>

<script type= "Text/javascript" src= "Js/jquery.form.js" ></script>
<script type= "Text/javascript" src= "Js/jquery.validate.js" ></script>

<script type= "Text/javascript" src= "Js/usercenter.js" ></script>

Form form for login interface:

<form class= "Form-horizontal" method= "post" id= "LoginForm" >
<div id= "Iyoutingche-formgroup" >
<label for= "InputEmail3" class= "col-sm-2 control-label" > Email </label>
<div class= "Col-sm-10" >
<input type= "text" class= "Form-control" name= "User_email" value= "${cookie.email.value}" id= "email" placeholder= " Email ">
</div>
</div>
<div id= "Iyoutingche-formgroup" >
<label for= "InputPassword3" class= "col-sm-2 Control-label" > Password </label>
<div class= "Col-sm-10" >
<input type= "Password" class= "Form-control" value= "${cookie.password.value}" Name= "User_password" id= "password" Placeholder= "Password" >
</div>
</div>
<div id= "Form-group" >
<div class= "Col-sm-offset-2 col-sm-10" >
<div class= "checkbox" >
<label>
<input type= "checkbox" Name= "Isauto" value= "1" checked= "checked" > Remember password
</label>
</div>
</div>
</div>
<div class= "Form-group" >
<div class= "Col-sm-offset-2 col-sm-10" >
<span id= "Info" ></span>
<button type= "Submit" class= "btn btn-default btn-lg" id= "loginbtn" > Login </button>
<a href= "" > not registered? </a>
</div>
</div>
</form>

Usercenter.js file:

$ ("#LoginForm"). Validate ({
rules:{
User_email: {
Required:true,
Email:true
},
user_password:{
Required:true,
Minlength:5,
},
},
messages:{
user_email:{
Required: "Please enter your mailbox",
Email: "Please enter the correct email address"
},
user_password:{
Required: "Please enter your password",
Minlength:jQuery.validator.format ("Enter characters not less than 5 digits"),
},
},
Submithandler:function (form) {
$ (form). Ajaxsubmit ({
URL: ' Usercheckloginser ',
Type: ' POST ',
Success:function (data) {
if (data== "true") {
var email = $ ("#email"). Val ();
Set cookies
$.cookie (' CookieName ', Email,{expires:7,path: '/', secure:false,raw:false});
$.cookie (' CookieName ', email,{expires:7});
Cookiesave = $.cookie (' cookiename ', email);
Location.reload ();
}else{
$ ("#info"). Append ("<b> wrong user name or password </b><br/>");
}
}
});
}
});

Note When you use Ajaxsubmit to submit a form form to the background, you must introduce the Jquery.form.js file, or the form will not be submitted. This is not written in other blogs, it is found by themselves.
