defaultOptions(rule)
defaultOptions is a static method that the UI component class supports. The following code demonstrates how to specify default properties for all instances of the Tooltip UI component in an application executed on the desktop.
jQuery
DevExpress.ui.dxTooltip.defaultOptions({ device: { deviceType: "desktop" }, options: { // Here go the Tooltip options } });
Angular
import Tooltip from "devextreme/ui/tooltip"; // ... export class AppComponent { constructor () { Tooltip.defaultOptions({ device: { deviceType: "desktop" }, options: { // Here go the Tooltip options } }); } }
Vue
<template> <div> <DxTooltip id="tooltip1" /> <DxTooltip id="tooltip2" /> </div> </template> <script> import DxTooltip from "devextreme-vue/tooltip"; import Tooltip from "devextreme/ui/tooltip"; Tooltip.defaultOptions({ device: { deviceType: "desktop" }, options: { // Here go the Tooltip options } }); export default { components: { DxTooltip } } </script>
React
import React from "react"; import dxTooltip from "devextreme/ui/tooltip"; import Tooltip from "devextreme-react/tooltip"; class App extends React.Component { render () { dxTooltip.defaultOptions({ device: { deviceType: "desktop" }, options: { // Here go the Tooltip options } }) return ( <div> <Tooltip id="tooltip1" /> <Tooltip id="tooltip2" /> </div> ) } } export default App;
dispose()
After calling this method, remove the DOM element associated with the UI component:
$("#myTooltip").dxTooltip("dispose"); $("#myTooltip").remove();
Use this method only if the UI component was created with jQuery or pure JavaScript. In Angular, Vue, and React, use conditional rendering:
Angular
<dx-tooltip ... *ngIf="condition"> </dx-tooltip>
Vue
<template> <DxTooltip ... v-if="condition"> </DxTooltip> </template> <script> import DxTooltip from 'devextreme-vue/tooltip'; export default { components: { DxTooltip } } </script>
React
import React from 'react'; import Tooltip from 'devextreme-react/tooltip'; function DxTooltip(props) { if (!props.shouldRender) { return null; } return ( <Tooltip ... > </Tooltip> ); } class App extends React.Component { render() { return ( <DxTooltip shouldRender="condition" /> ); } } export default App;
