JavaScript/jQuery Switch - Getting Started
jQuery
Angular
Vue
React
The Switch component allows users to switch between ON (the value is true
) and OFF (the value is false
) states.
This tutorial shows how to add Switch to a page and configure its core features. The following sample shows the customization result:
Each section in this tutorial describes a single configuration step. You can also find the full source code in the following GitHub repository: getting-started-with-switch.
Create a Switch
jQuery
Add DevExtreme to your jQuery application and use the following code to create a Switch component:
$(function() { $("#switch").dxSwitch({ }); });
<html> <head> <!-- ... --> <script type="text/javascript" src="https://code.jquery.com/jquery-3.5.1.min.js"></script> <link rel="stylesheet" href="https://cdn3.devexpress.com/jslib/minor_23_2/css/dx.light.css"> <script type="text/javascript" src="https://cdn3.devexpress.com/jslib/minor_23_2/js/dx.all.js"></script> <script type="text/javascript" src="index.js"></script> </head> <body> <div id="switch"></div> </body> </html>
Angular
Add DevExtreme to your Angular application and use the following code to create a Switch component:
<dx-switch></dx-switch>
import { Component } from "@angular/core"; @Component({ selector: "app-root", templateUrl: "./app.component.html", styleUrls: ["./app.component.css"] }) export class AppComponent { }
import { BrowserModule } from "@angular/platform-browser"; import { NgModule } from "@angular/core"; import { AppComponent } from "./app.component"; import { DxSwitchModule } from "devextreme-angular"; @NgModule({ declarations: [ AppComponent ], imports: [ BrowserModule, DxSwitchModule ], providers: [ ], bootstrap: [AppComponent] }) export class AppModule { }
Vue
Add DevExtreme to your Vue application and use the following code to create a Switch component:
<template> <DxSwitch> </DxSwitch> </template> <script> import "devextreme/dist/css/dx.light.css"; import { DxSwitch } from "devextreme-vue/switch"; export default { components: { DxSwitch } } </script>
React
Add DevExtreme to your React application and use the following code to create a Switch component:
import React from "react"; import "devextreme/dist/css/dx.light.css"; import { Switch } from "devextreme-react/switch"; function App() { return ( <Switch> </Switch> ); } export default App;
Specify the Initial State
If you need to specify the initial state, assign a Boolean value to the value property. You can also change the Switch component labels. Use the switchedOnText and the switchedOffText properties.
jQuery
$(function() { $("#switch").dxSwitch({ value: false, }); });
Angular
<dx-switch [value]="false" > </dx-switch>
Vue
<template> <DxSwitch :value="false" /> </template> <script> // ... </script>
React
// ... function App() { // ... return ( <Switch value={false} /> ); } export default App;
Configure Size
The component allows you to change its width.
You can also use rtlEnabled property to enable the Right-to-Left layout.
jQuery
$(function() { $("#switch").dxSwitch({ // ... width: 80, rtlEnabled: true, }); });
Angular
<dx-switch ... [width]="80" [rtlEnabled]="true" > </dx-switch>
Vue
<template> <DxSwitch ... :width="80" :rtlEnabled="true" /> </template> <script> // ... </script>
React
// ... function App() { // ... return ( <Switch ... width={80} rtlEnabled={true} /> ); } export default App;
Define a Hint
The following code specifies the hint that appears when users hover the mouse pointer over the Switch.
jQuery
$(function() { $("#switch").dxSwitch({ // ... hint: "Click to switch on", onValueChanged(e) { const messageText= e.value ? "Click to switch off" : "Click to switch on"; e.component.option("hint", messageText); // ... } }); });
Angular
<dx-switch ... [hint]="hintMessage" (onValueChanged)="onValueChanged($event)" > </dx-switch>
import { Component } from "@angular/core"; // ... @Component({ selector: "app-root", templateUrl: "./app.component.html", styleUrls: ["./app.component.css"] }) export class AppComponent { hintMessage: string = "Click to switch on"; onValueChanged(e: {value: boolean}) { this.hintMessage = e.value ? "Click to switch off" : "Click to switch on"; // ... } }
Vue
<template> <DxSwitch ... :hint="hintMessage" @value-changed="onValueChanged" /> </template> <script> import { DxSwitch } from "devextreme-vue/switch"; // ... export default { components: { DxSwitch }, data() { return { hintMessage: "Click to switch on", }; }, methods: { onValueChanged(e) { this.hintMessage = e.value ? "Click to switch off" : "Click to switch on"; // ... } } } </script>
React
import React, { useState, useCallback } from "react"; import "devextreme/dist/css/dx.light.css"; import { Switch } from "devextreme-react/switch"; function App() { const [hintMessage, setHintMessage] = useState("Click to switch on"); const onValueChanged = useCallback((e) => { const messageText = e.value ? "Click to switch off" : "Click to switch on"; setHintMessage(messageText); // ... }, []); return ( <Switch ... hint={hintMessage} onValueChanged={onValueChanged} /> ); } export default App;
Handle Value Change
Users can change a component value (state) with a mouse click, SPACE key, or tap. Implement the onValueChanged callback to handle value changes.
The following code displays a notification every time users change the Switch state:
jQuery
$(function() { $("#switch").dxSwitch({ // ... onValueChanged(e) { // ... const stateLabel = e.value ? "ON" : "OFF"; DevExpress.ui.notify(`The component is switched ${stateLabel}`); } }); });
Angular
<dx-switch ... (onValueChanged)="onValueChanged($event)" > </dx-switch>
import { Component } from "@angular/core"; import notify from "devextreme/ui/notify"; @Component({ selector: "app-root", templateUrl: "./app.component.html", styleUrls: ["./app.component.css"] }) export class AppComponent { // ... onValueChanged(e: {value: boolean}) { // ... const stateLabel = e.value ? "ON" : "OFF"; notify(`The component is switched ${stateLabel}`); } }
Vue
<template> <DxSwitch ... @value-changed="onValueChanged" /> </template> <script> // ... import { DxSwitch } from "devextreme-vue/switch"; import notify from "devextreme/ui/notify"; export default { components: { DxSwitch }, // ... methods: { onValueChanged(e) { // ... const stateLabel = e.value ? "ON" : "OFF"; notify(`The component is switched ${stateLabel}`); } } } </script>
React
import React, { useState, useCallback } from "react"; import "devextreme/dist/css/dx.light.css"; import { Switch } from "devextreme-react/switch"; import notify from "devextreme/ui/notify"; function App() { // ... const onValueChanged = useCallback((e) => { // ... const stateLabel = e.value ? "ON" : "OFF"; notify(`The component is switched ${stateLabel}`); }, []); return ( <Switch ... onValueChanged={onValueChanged} /> ); } export default App;
