When you want to have user selectable rows in DataTables, it is relatively trivial when using DOM based data - but when using server-side processing, DataTables doesn't retain DOM row elements over pages / filtering etc. As such, you will need to keep a track of which rows a user as selected and mark them as selected on each draw.
This is shown in this demo, which uses a unique ID assigned to the TR element (this is done
automatically through the use of the DT_RowId special property returned as part of the
object given by the server for each row) to track which rows are selected and reselect them is
appropriate on a draw.
| Name | Position | Office | Extn. | Start date | Salary |
|---|---|---|---|---|---|
| Name | Position | Office | Extn. | Start date | Salary |
The Javascript shown below is used to initialise the table shown in this example:
$(document).ready(function() {
var selected = [];
$("#example").dataTable({
"processing": true,
"serverSide": true,
"ajax": "scripts/ids-arrays.php",
"rowCallback": function( row, data, displayIndex ) {
if ( $.inArray(data.DT_RowId, selected) !== -1 ) {
$(row).addClass('selected');
}
}
});
$('#example tbody').on('click', 'tr', function () {
var id = this.id;
var index = $.inArray(id, selected);
if ( index === -1 ) {
selected.push( id );
} else {
selected.splice( index, 1 );
}
$(this).toggleClass('selected');
} );
} );
In addition to the above code, the following Javascript library files are loaded for use in this example:
The HTML shown below is the raw HTML table element, before it has been enhanced by DataTables:
This example uses a little bit of additional CSS beyond what is loaded from the library files (below), in order to correctly display the table. The additional CSS used is shown below:
The following CSS library files are loaded for use in this example to provide the styling of the table:
This table loads data by Ajax. The latest data that has been loaded is shown below. This data will update automatically as any additional data is loaded.
