我使用數(shù)據(jù)表制作了一個頁面。但是隨著數(shù)據(jù)量的增加，加載數(shù)據(jù)的速度變慢了，所以我們嘗試進行分頁。但是我不知道如何在當前代碼中修改它。應(yīng)該如何修改？在這個我的數(shù)據(jù)表腳本中 $(function() { $('#datatable1').DataTable({ responsive: true, order: [[ 1, "desc" ], [ 2, "desc"]], language: { searchPlaceholder: 'Search...', sSearch: '', lengthMenu: '_MENU_ items/page', }, dom : 'Bfrtip', buttons: [ 'copy', 'excel', 'print' ] }); });在這個sql查詢中 $sql = "SELECT id, DATE_FORMAT(tranDate,'%Y-%m-%d') as tranDate, tranTime, date, cmd, paymethod, amount, orgRefNo, orgTranDate FROM noti_card_data WHERE mbrNO = '1'";in this table view code if($result = mysqli_query($link, $sql)){ if(mysqli_num_rows($result) > 0){ echo "<table id='datatable1' class = table style = 'width: 100%; font-size:12.5px; font-family:nanum; background-color:transparent;'>"; echo "<thead >"; echo "<tr>"; echo "<th>No</th>"; echo "<th>amount</th>"; echo "</tr>"; echo "</thead>"; echo "<tbody>"; while($row = mysqli_fetch_array($result)){ echo "<tr>"; echo "<td>" . $row['id'] . "</td>"; echo "<td>" . number_format($row['amount']) . "</td>"; echo "</tr>"; } echo "</tbody>"; echo "</table>"; // Free result set mysqli_free_result($result); } else{ } } else{ echo "ERROR: Could not able to execute $sql. " . mysqli_error($link); } // Close connection mysqli_close($link); 在這個視圖中如何使用分頁

您可以通過獲取分頁所在的當前頁面所需的數(shù)據(jù)集來實現(xiàn)此目的，而不是獲取查詢返回的所有數(shù)據(jù)集。
例如：
想象一下你在分頁的第 1 頁。如果你每頁只需要 100 個項目，那么你可以將查詢檢索的項目限制為 100 個，這樣可以更快地檢索數(shù)據(jù)，因為而不是獲取每個數(shù)據(jù)從查詢中設(shè)置您剛剛獲得 100 以顯示在當前頁面中。
您必須在網(wǎng)址中傳遞頁碼。想象一下您的網(wǎng)址就像下面提到的那樣。
http://localhost/pagination.php?page=2
// getting the current page to set the starting point to get data.
if (isset($_GET['page'])) {
$curPage = $_GET['page'];
} else {
$curPage = 1;
}
//number of items you need per a page
$labels_per_page = 100;
//setting the starting point according to the page no.
if($curPage>1){
$start = ($curPage-1)*$labels_per_page;
}else{
$start = 0;
}
//limiting the query according to the starting point nd items per page
$sql = "SELECT id, DATE_FORMAT(tranDate,'%Y-%m-%d') as tranDate, tranTime, date, cmd, paymethod, amount, orgRefNo, orgTranDate FROM noti_card_data WHERE mbrNO = '1' LIMIT ".$start .','.$labels_per_page ;
