После визуализации сетки jQuery может искать флажки.
Вы можете использовать классы PQ Grid для выбора строк.
.pq-grid-row является классом для каждой строки. .pq-grid-oddRow является классом для нечетных строк. .pq-grid-title-row является классом для строки заголовка.
Таким образом, чтобы получить четные строки, вы можете использовать селектор всех строк и селектор .not().
Чтобы установить флажки, используйте селектор атрибута .
// Disable the columns checkboxes (check all)
$(".pq-grid-title-row [type='checkbox']").prop("disabled",true);
// Disable checkboxes on even rows.
$(".pq-grid-row:not(.pq-grid-oddRow) [type='checkbox']").prop("disabled",true);
// Disable checkboxes on odd rows.
$(".pq-grid-oddRow [type='checkbox']").prop("disabled",true);
Вот фрагмент кода, в котором флажки в нечетных строках и столбец «проверить все» отключены.
