私の例では、ボタン（#Bt_CancTable）でいくつかの行を削除しようとしていますが、私は給与計算で自動的にページ合計を更新する必要があります。行を削除しますが、合計は変更されません
表示される行の数を変更すると、合計が動的に更新されます。チェックされた行を削除する必要があります。
ありがとうございます。
$(document).ready(function() {
$('#Bt_CancTable').click(function() {
$('#example').find('tr').each(function() {
var row = $(this);
if (row.find('input[type="checkbox"]').is(':checked')) {
console.log('Deleted ROW: '+row.index());
row.remove();
};
});
});
$('#example').DataTable({
columnDefs: [ {
orderable: false,
targets: 0,
className: 'dt-body-center',
render: function (data, type, full, meta){
return '<input type="checkbox" name="id[]" value="' + $('<div/>').text(data).html() + '">';
}
} ],
select: {
style: 'os',
selector: 'td:first-child'
},
order: [[ 1, 'asc' ]],
footerCallback: function (row, data, start, end, display) {
var api = this.api(), data;
// Remove the formatting to get integer data for summation
var intVal = function (i) {
return typeof i === 'string' ?
i.replace(/[\$,]/g, '')*0.001 :
typeof i === 'number' ?
i : 0;
};
// Total over all pages
total = api
.column(5)
.data()
.reduce(function (a, b) {
return intVal(a) + intVal(b);
}, 0);
// Total over this page
pageTotal = api
.column(5, { page: 'current'})
.data()
.reduce(function (a, b) {
return intVal(a) + intVal(b);
}, 0);
// Update footer
$(api.column(5).footer()).html(
'K$ '+pageTotal +' ('+ total +' K$ total)'
);
}
});

すべてのコードをスニペットに挿入しました。「コードスニペットを実行」ボタンでテストできます。あなたが黄色いボタン "Cancella selezionati"で行を削除するときにあなたがテストするならば、給料の列の最後の合計は変更されません（私は変更が必要です）が、表示される行の数を変更する場合は、 "給与の変化の合計。 ありがとうございました – MadCat
問題は、行を削除するときだと思います。 $（ '＃Bt_CancTable'）。クリック（function（）{...行を削除した後、削除した行を表示する行の数が変更された場合） – MadCat
