SMART datagrid v.1 > Classes > TreeDataRow

DataLudi.TreeDataRow.children  property

将正下方的子行返回为数组。 

如果没有子行，就会返回空数组。 可以通过getDescendants，获取所有子孙行的列表。 

Getter

function children(): Array

    $('#checkSum').click(function () {
        var row = tree.focusedRow();
        if (row) {
            var sum = 0;
            var rows = row.children();
            for (var i = rows.length; i--;) {
                sum += rows[i].getData('amount');
            }
            if (sum > 10000) {
                alert('Too large !');
            }
        }
    });
