我有一個需求,我需要將第一列及其後續行值添加爲Checked或Unchecked複選框。我現在面臨的問題是服務器端的動態數據之一。這裏,列名和行值都來自服務器端。這是代碼。如何獲得Jquery Datatable的第一列爲複選框

$('#SettingsDatatable').dataTable({ 
    "order": [], 
    "dom": "Bfrtip", 
    "buttons": ["copy", "csv", "excel", "pdf", "print"], 
    "columnDefs": [{ 
    "className": "dt-center", "orderable": false, "width": 20 
         }], 
    "columns": dataObject[0].columns, 
    "data": dataObject[0].data 
        }); 

如何添加複選框列以及如何基於從dataObject[0].data值它被選中和未選中?請幫忙。謝謝。

我有類似的種溶液,其中i產生UI,其中行/列是由服務器生成的側。你只需要在那裏實現,所以客戶端將相應地呈現UI對象。 –

@Jits如何做到這一點,數據是從服務器端來的Json格式? – Lara

你有沒有數據來自mysql表? –

可以使用columnDefs呈現自定義HTML

var dataObject = [{ 
 
    "columns": [{ 
 
    "title": "Select" 
 
    }, { 
 
    "title": "DbColumn Name" 
 
    }, { 
 
    "title": "UserColumn Name" 
 
    }], 
 
    "data": [ 
 
    ["False", "STARTDATE", ""], 
 
    ["True", "ENDDATE", ""], 
 
    ["False", "CLASS ", ""], 
 
    ["True", "AUDIT_DATE ", ""] 
 
    ] 
 
}]; 
 

 
$('#SettingsDatatable').dataTable({ 
 
    "order": [], 
 
    "dom": "Bfrtip", 
 
    "buttons": ["copy", "csv", "excel", "pdf", "print"], 
 
    "columnDefs": [{ 
 
    "targets": 0, 
 
    "render": function(data, type, full, meta) { 
 
     return '<input type="checkbox" ' + (data == 'True' ? 'checked' : '') + ' />'; 
 
    } 
 
    }, { 
 
    "className": "dt-center", 
 
    "orderable": false, 
 
    "width": 20 
 
    }], 
 
    "columns": dataObject[0].columns, 
 
    "data": dataObject[0].data 
 
});

如何根據我的服務器端值檢查未選中,假設我有三列,其值爲'[{「列」:[{「title」:「Select」},{「title」:「DbColumn Name」} ,{「title」:「UserColumn Name」}],「data」:[[「False」,「STARTDATE」,「」],[「True」,「ENDDATE」,「」],[「False」 CLASS「,」「],[」True「,」AUDIT_DATE「,」「]]}]' – Lara

這裏是使用的解決方案PHP,MySQL的& jQuery的。請根據您的需要進行轉換

  1. 將您的數據庫從MySQL更改爲Oracle。
  2. 更改服務器端下拉以使用複選框。
  3. 請給出$ settingsDatatableServer變量(代碼中提到的服務器端文件)的確切路徑。

客戶端側(jQuery的):

settingsDatatable = $("#SettingsDatatable").dataTable({ 
    aLengthMenu: [ [10, 25, 50, 100, "-1"], [10, 25, 50, 100, "All"] ], 
     iDisplayLength: 10, 
     searching: true, 
     "aaSorting": [], 
     "order": [[ 0, "asc" ]], 
     "sPaginationType": "full_numbers", 

     "bProcessing": true, 
     "serverSide": true, 
     "bDestroy": true, 
     "cache": false, 
     "sAjaxSource": "<?php echo $settingsDatatableServer; ?>", 

     "aoColumnDefs": [ 
      { "bSortable": false, "aTargets": [ 1, 2, 3, 4, 5 ] }, 
      { "data": "column1" }, 
      { "data": "column2" }, 
      { "data": "column3" }, 
      { "data": "column4" }, 
      { "data": "column5" }, 
     ], 
    }); 

服務器側(PHP + MySQL的)

<?php 

if($_GET) { 

    $aColumns = array('column1', 'column2', 'column3', 'column4', 'column5'); 

    $sIndexColumn = "column1";

    $sSql['server'] = DB_HOST; 

    function fatal_error ($sErrorMessage = '') 
    { 
     header($_SERVER['SERVER_PROTOCOL'] .' 500 Internal Server Error'); 
     die($sErrorMessage); 
    } 

    if (! $sSql['link'] = mysqli_connect($sSql['server'], $sSql['user'], $sSql['password'] )) 
    { 
     fatal_error('Could not open connection to server'); 
    } 

    if (! mysqli_select_db($sSql['link'], $sSql['db'])) 
    { 
     fatal_error('Could not select database ');
