Pluralization

In some cases you may want to display custom messages that depend on item counts. This is especially important in certain cultures such as Polish. The format method supports that by accepting format strings that contain pluralization rules encoded as JSON objects. For example, choose the number of items and see the formatted output below:

import 'bootstrap.css'; import '@grapecity/wijmo.styles/wijmo.css'; import * as wijmo from '@grapecity/wijmo'; import * as input from '@grapecity/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 }); }
