Accordion UI组件包含几个面板,一个显示在另一个面板下面。

本教程展示如何将Accordion(折叠)添加到页面并配置组件的核心设置,因此开发者将创建以下UI组件:

本教程中的每一节都描述了单个配置步骤,开发者也可以在以下GitHub存储库中找到完整的源代码:getting-started-with-accordion。

创建一个Accordion(折叠)

jQuery

将DevExtreme添加到jQuery应用程序中,并使用以下代码创建Accordion:

index.js

$(function() {$("#accordion").dxAccordion({ });});

index.html

<html><head><!-- ... --><script type="text/javascript" src=";></script><link rel="stylesheet" href=";><script type="text/javascript" src=";></script><script type="text/javascript" src="index.js"></script></head><body><div id="accordion"></div></body></html>

Angular

将DevExtreme添加到你的Angular应用中,并使用以下代码创建一个Accordion:

app.component.html

<dx-accordion></dx-accordion>

app.component.ts

import { Component } from '@angular/core';@Component({selector: 'app-root',templateUrl: './app.component.html',styleUrls: ['./app.component.css']})export class AppComponent {}

app.module.ts

import { BrowserModule } from '@angular/platform-browser';import { NgModule } from '@angular/core';import { AppComponent } from './app.component';import { DxAccordionModule } from 'devextreme-angular';@NgModule({declarations: [AppComponent],imports: [BrowserModule,DxAccordionModule],providers: [ ],bootstrap: [AppComponent]})export class AppModule { }

Vue

将DevExtreme添加到您的Vue应用程序中,并使用以下代码创建Accordion:

App.vue

<template><DxAccordion /></template><script>import 'devextreme/dist/css/dx.light.css';import { DxAccordion } from 'devextreme-vue/accordion';export default {components: {DxAccordion}}</script>

React

将DevExtreme添加到React应用程序中,并使用以下代码创建Accordion:

App.js

import React from 'react';import 'devextreme/dist/css/dx.light.css';import { Accordion } from 'devextreme-react/accordion';function App() {return (<Accordion />);}export default App;
将Accordion(折叠)绑定到数据

开发者可以从数据源或项目数组中显示Accordion数据,注意每个数据源对象必须包含标题字段,其值指定面板的标题。

jQuery

index.js

$(function() {$("#accordion").dxAccordion({dataSource: employees});});

index.html

<head><!-- ... --><script type="text/javascript" src="data.js"></script></head>data.jsconst employees = [{ID: 1,Prefix: 'Mr.',FirstName: 'John',LastName: 'Heart',Position: 'CEO',State: 'California',BirthDate: '1964/03/16',},{ID: 2,Prefix: 'Mrs.',FirstName: 'Olivia',LastName: 'Peyton',Position: 'Sales Assistant',State: 'California',BirthDate: '1981/06/03',},{ID: 3,Prefix: 'Mr.',FirstName: 'Robert',LastName: 'Reagan',Position: 'CMO',State: 'Arkansas',BirthDate: '1974/09/07',},{ID: 4,Prefix: 'Ms.',FirstName: 'Greta',LastName: 'Sims',Position: 'HR Manager',State: 'Georgia',BirthDate: '1977/11/22',}];

Angular

app.component.html

<dx-accordion[dataSource]="employees"></dx-accordion>app.component.tsimport { Component } from '@angular/core';import { Employee, Service } from './app.service';@Component({selector: 'app-root',templateUrl: './app.component.html',styleUrls: ['./app.component.css'],providers: [Service],})export class AppComponent {employees: Employee[];constructor(private service: Service) {this.employees = service.getEmployees();}}app.service.tsimport { Injectable } from '@angular/core';export class Employee {ID: number | undefined;FirstName: string | undefined;LastName: string | undefined;Prefix: string | undefined;Position: string | undefined;BirthDate: string | undefined;State: string | undefined;}const employees: Employee[] = [{ID: 1,Prefix: 'Mr.',FirstName: 'John',LastName: 'Heart',Position: 'CEO',State: 'California',BirthDate: '1964/03/16',},{ID: 2,Prefix: 'Mrs.',FirstName: 'Olivia',LastName: 'Peyton',Position: 'Sales Assistant',State: 'California',BirthDate: '1981/06/03',},{ID: 3,Prefix: 'Mr.',FirstName: 'Robert',LastName: 'Reagan',Position: 'CMO',State: 'Arkansas',BirthDate: '1974/09/07',},{ID: 4,Prefix: 'Ms.',FirstName: 'Greta',LastName: 'Sims',Position: 'HR Manager',State: 'Georgia',BirthDate: '1977/11/22',}];@Injectable()export class Service {getEmployees() {return employees;}}

Vue

App.vue

<template><DxAccordion:data-source="employees"/></template><script>// ...import { employees } from './data';export default {components: {DxAccordion},data() {return {employees}}}</script>data.jsexport const employees = [{ID: 1,Prefix: 'Mr.',FirstName: 'John',LastName: 'Heart',Position: 'CEO',State: 'California',BirthDate: '1964/03/16',},{ID: 2,Prefix: 'Mrs.',FirstName: 'Olivia',LastName: 'Peyton',Position: 'Sales Assistant',State: 'California',BirthDate: '1981/06/03',},{ID: 3,Prefix: 'Mr.',FirstName: 'Robert',LastName: 'Reagan',Position: 'CMO',State: 'Arkansas',BirthDate: '1974/09/07',},{ID: 4,Prefix: 'Ms.',FirstName: 'Greta',LastName: 'Sims',Position: 'HR Manager',State: 'Georgia',BirthDate: '1977/11/22',}];

React

App.js

// ...import { employees } from './data';function App() {return (<AccordiondataSource={employees}/>);}export default App;

data.js

export const employees = [{ID: 1,Prefix: 'Mr.',FirstName: 'John',LastName: 'Heart',Position: 'CEO',State: 'California',BirthDate: '1964/03/16',},{ID: 2,Prefix: 'Mrs.',FirstName: 'Olivia',LastName: 'Peyton',Position: 'Sales Assistant',State: 'California',BirthDate: '1981/06/03',},{ID: 3,Prefix: 'Mr.',FirstName: 'Robert',LastName: 'Reagan',Position: 'CMO',State: 'Arkansas',BirthDate: '1974/09/07',},{ID: 4,Prefix: 'Ms.',FirstName: 'Greta',LastName: 'Sims',Position: 'HR Manager',State: 'Georgia',BirthDate: '1977/11/22',}];
