基数詞

場合によっては、項目数に依存するカスタムメッセージを表示することができます。これは、ポーランド語などの特定のカルチャーでは特に重要です。formatメソッドは、JSONオブジェクトとしてエンコードされた基数詞の規則を含む書式文字列を受け入れることで、このような動作をサポートしています。次の例で、項目数を選択して、書式設定された出力を確認してください。

import 'bootstrap.css'; import '@mescius/wijmo.styles/wijmo.css'; import * as wijmo from '@mescius/wijmo'; import * as input from '@mescius/wijmo.input'; // document.readyState === 'complete' ? init() : window.onload = init; // function init() { // build format string with pluralization let fmtPluralStr = JSON.stringify({ count: 'count', when: { 0: 'No items selected.', 1: 'A single item is selected.', 2: 'A pair is selected.', 3: 'A trio is selected.', 4: 'A quartet is selected.', 'other': '{count:n0} items are selected.' } }); // // let the user choose the number of items let theInputNumber = new input.InputNumber('#theInputNumber', { valueChanged: (sender) => { document.querySelector('#msg').textContent = wijmo.format(fmtPluralStr, { count: sender.value }); }, step: 1, value: 1 }); }
