The use of jquery encapsulated JS file to form validation, improve the efficiency of web development. I have written an example of validation to show you.
The validation methods contained in the instance are not comprehensive, and if you don't want it, you can

Form form for login interface:

</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

<div class= "Form-group" >
<div class= "Col-sm-offset-2 col-sm-10" >

<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.
