コンボコントロールで任意のソート処理を実行する方法について紹介します。
ソート
コンボコントロールのsortメソットでは、ソート条件（並び替える列と並び替えの方法）を指定して、ドロップダウンリストをソートすることができます。
isAscをtrueにすると昇順で、falseにすると降順でソートされます。
また、sortメソットの引数にソート関数を指定して、任意のソート処理を実行することができます。
以下はソート実行時にName列とValue列を昇順にソートするサンプルです。
上記のサンプルのように、ソート関数では複数列をソートしたい場合に有効です。
import '@mescius/inputman/CSS/gc.inputman-js.css';
import { InputMan } from '@mescius/inputman';
import orders from './data';
import './styles.css';
InputMan.appearanceStyle = InputMan.AppearanceStyle.Modern;
const columns = [
{ name: 'id', label: '商品コード', width: 80 },
{ name: 'product', label: '商品名', width: 200 },
{ name: 'date', label: '受注日', width: 120 },
{ name: 'price', label: '単価', width: 80 },
{ name: 'amount', label: '数量', width: 80 },
];
const gcComboBox = new InputMan.GcComboBox(document.getElementById('gcComboBox'), {
items: orders,
columns: columns,
displayMemberPath: 'product',
valueMemberPath: 'product',
dropDownWidth: 'auto',
});
const gcComboBox2 = new InputMan.GcComboBox(document.getElementById('gcComboBox2'), {
items: orders,
columns: columns,
displayMemberPath: 'product',
valueMemberPath: 'product',
dropDownWidth: 'auto',
});
//ソート条件によるソート(昇順)
document.getElementById('ascId').addEventListener('change', (e) => {
let sortIdInfo = { name: 'id', isAsc: true };
e.target.checked ? gcComboBox.sort(sortIdInfo) : gcComboBox.sort(null);
});
//ソート関数によるソート
document.getElementById('customSort').addEventListener('change', (e) => {
if (e.target.checked === true) {
gcComboBox2.sort(ascFunc);
} else {
gcComboBox2.sort(null);
}
});
//昇順関数
const ascFunc = (first, second) => {
if (first.item.id == second.item.id) {
return first.item.price - second.item.price;
}
return first.item.id - second.item.id;
}
