jQWidgets jqxValidator rules Property

Last Updated : 05 Nov, 2021

jQWidgets is a JavaScript framework for making web-based applications for PC and mobile devices. It is a very powerful, optimized, platform-independent, and widely supported framework. The jqxValidator is used for validation of the HTML form with the help of JavaScript. It has some set of build-in rules according to the requirement for the validation of the user inputs, e-mail, SSN, ZIP, max value, min value, interval, etc. The custom rules can also be written as per the specific requirements.

The rules property is used for setting rules for the specified jqxValidator.

Syntax:

{ 
   input: 'selector-of-the-input',  
   message: 'Custom message on error',  
   action: 'Custom action (keyup, change...etc)',  
   rule: 'Build rule(ssn, phone, email...) 
          or custom function',
   position: 'Position of the hint (format pos:x,y)',  
   hintRender: 'Function for hint rendering'
}
