We recommend that you add this file to messages_cn.js and introduce it on the page.
<Script src = ../js/messages_cn.js type = text/javascript> </script>

Iv. usage method 1. Write the validation rule to the control

<Script src = ../js/jquery. js type = text/javascript> </script>
<Script src = ../js/jquery. validate. js type = text/javascript> </script>
<Script src =./js/jquery. metadata. js type = text/javascript> </script>

$ (). Ready (function (){
$ (# SignupForm). validate ();
});

 

 

To use class = {}, you must introduce the package: jquery. metadata. js.

You can use the following method to modify the prompt content:
Class = {required: true, minlength: 5, messages: {required: 'Enter the content '}}

When using the sort to keyword, the following content must be enclosed in quotation marks, as shown in the following code:
Class = {required: true, minlength: 5, failed to: '# password '}

2. Write validation rules to js Code

$ (). Ready (function (){
$ (# SignupForm). validate ({
Rules :{
Firstname: required,
Email :{
Required: true,
Email: true
},
Password :{
Required: true,
Minlength: 5
},
Confirm_password :{
Required: true,
Minlength: 5,
Failed to: # password
}

});
