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。

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