コンボボックス:項目の自動追加

このサンプルは、 ComboBoxAutoComplete、およびListBoxを含むいくつかのコントロールを使用します。編集が有効になっているときに、ComboBoxや他の入力コントロールに項目を追加する簡単な方法を示します。

import 'bootstrap.css'; import '@mescius/wijmo.styles/wijmo.css'; import './styles.css'; // import * as wijmo from '@mescius/wijmo'; import * as input from '@mescius/wijmo.input'; // document.readyState === 'complete' ? init() : window.onload = init; // function init() { let countries = new wijmo.ObservableArray(['アメリカ', 'ドイツ', 'イギリス', '日本', 'イタリア', 'ギリシャ']); // new input.ComboBox('#theCombo', { itemsSource: countries, isEditable: true, lostFocus: lostFocus }); // new input.AutoComplete('#theAutoComplete', { itemsSource: countries, lostFocus: lostFocus }); // new input.ListBox('#theList', { itemsSource: countries }); // // add item to the list when a control loses focus function lostFocus(sender) { let item = sender.text; if (item && countries.indexOf(item) < 0) { countries.push(item); } } }
