コンボボックス:数値と日付

ComboBoxは、文字列だけでなく数値日付もサポートします。数値または日付の配列をComboBoxコントロールに連結できます。このサンプルは、wijmo.Globalize.formatメソッドを使用して日付をフォーマットする方法を示します。

import 'bootstrap.css'; import '@grapecity/wijmo.styles/wijmo.css'; import './styles.css'; import { Globalize } from '@grapecity/wijmo'; import { ComboBox } from '@grapecity/wijmo.input'; document.readyState === 'complete' ? init() : window.onload = init; function init() { // select a number let theComboNumber = new ComboBox('#theComboNumber', { selectedIndexChanged: sender => { setText('theNumber', sender.selectedItem); }, itemsSource: [2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71], }); // select a date let theComboDate = new ComboBox('#theComboDate', { selectedIndexChanged: sender => { setText('theDate', Globalize.format(sender.selectedItem, 'd')); }, itemsSource: [new Date(2019, 0, 1), new Date(2019, 1, 12), new Date(2019, 1, 22), new Date(2019, 4, 13), new Date(2019, 4, 24), new Date(2019, 8, 19)], formatItem: (sender, e) => { e.item.textContent = Globalize.format(e.data, 'd'); }, }); // show text in an element on the page function setText(id, value) { document.getElementById(id).textContent = value; } }
