ツリービュー:アコーディオン

アコーディオンは複数ペインのパネルで、一度に1つのパネルだけを展開した状態に保ちます。アコーディオンは一般的にナビゲーションに使用されます。アコーディオンを実装するためにTreeViewコントロールを使うことができます。このサンプルは、ヘッダー表示をカスタマイズし、グリフを非表示にし、autoCollapseプロパティをtrueに設定することによって、TreeViewとCSSを使用してアコーディオンを作成します。

import 'bootstrap.css'; import '@grapecity/wijmo.styles/wijmo.css'; import './styles.css'; import * as wjNav from '@grapecity/wijmo.nav'; import * as wjCore from '@grapecity/wijmo'; import { getData } from './data'; // document.readyState === 'complete' ? init() : window.onload = init; // function init() { // // create the tree var tree = new wjNav.TreeView('#theTree', { itemsSource: getData(), displayMemberPath: 'header', childItemsPath: 'items', isContentHtml: true, isAnimated: true }); // // toggle accordion style document.getElementById('customCss').addEventListener('click', function (e) { wjCore.toggleClass(tree.hostElement, 'accordion', e.target.checked); }); // // handle clicks on accordion items tree.hostElement.addEventListener('click', function (e) { if (e.target.tagName == 'A') { var msg = document.getElementById('msg'); msg.innerHTML = wjCore.format('<b>{href}</b>へ移動', e.target); e.preventDefault(); } }); }
