dispose()
After calling this method, remove the DOM element associated with the widget:
$("#myValidator").dxValidator("dispose"); $("#myValidator").remove();
Use this method only if the widget was created with jQuery or pure JavaScript. In Angular, Vue, and React, use conditional rendering:
Angular
<dx-validator ... *ngIf="condition"> </dx-validator>
Vue
<template> <DxValidator ... v-if="condition"> </DxValidator> </template> <script> import DxValidator from 'devextreme-vue/validator'; export default { components: { DxValidator } } </script>
React
import React from 'react'; import Validator from 'devextreme-react/validator'; function DxValidator(props) { if (!props.shouldRender) { return null; } return ( <Validator ... > </Validator> ); } class App extends React.Component { render() { return ( <DxValidator shouldRender="condition" /> ); } } export default App;

ID:
// Modular approach import Validator from "devextreme/ui/validator"; ... let element = document.getElementById("myValidator"); let instance = Validator.getInstance(element) as Validator; // Non-modular approach let element = document.getElementById("myValidator"); let instance = DevExpress.ui.dxValidator.getInstance(element);
