dispose()
After calling this method, remove the DOM element associated with the widget:
$("#myCircularGauge").dxCircularGauge("dispose"); $("#myCircularGauge").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-circular-gauge ... *ngIf="condition"> </dx-circular-gauge>
Vue
<template> <DxCircularGauge ... v-if="condition"> </DxCircularGauge> </template> <script> import DxCircularGauge from 'devextreme-vue/circular-gauge'; export default { components: { DxCircularGauge } } </script>
React
import React from 'react'; import CircularGauge from 'devextreme-react/circular-gauge'; function DxCircularGauge(props) { if (!props.shouldRender) { return null; } return ( <CircularGauge ... > </CircularGauge> ); } class App extends React.Component { render() { return ( <DxCircularGauge shouldRender="condition" /> ); } } export default App;
