Validation

Form validation is the process of checking the data entered into a form to ensure that it's valid and complete.

This helps to prevent users from submitting forms with invalid data, which can cause problems for the application that's processing the form.

Form validation can be performed using a variety of methods, including:

Name Description
Required If enabled, then the field value can't be empty, otherwise an error message is emitted
Regular expressions Used to match patterns in text. They can be used to validate the format of data, such as email addresses, phone numbers, and dates
Custom Validation Rules (rule, value, callback) => {
rule: Verification rule, you can view the verification configuration information through this parameter; rule.field can get the field identifier of the current verification
value: Value of the current field
callback: Callback function (must be called) upon completion of validation; callback('Error message')/ callback(new Error('Error message')). These are two ways to return an error message

Info

  1. Regular expressions should be wrapped with //, as in:/^1[3456789]\d{9}$/"
  2. The callback() function is also called to verify success in the custom validation method.
