Often when using server-side processing you will find that it can be useful to have a specific ID on each row (the primary key value from the database for
example). By assigning the ID you want to apply to each row using the property DT_RowId of the data source object for each row, DataTables will
automatically add it for you.
In addition to DT_RowId there are two other properties which perform similar actions: DT_RowClass and DT_RowData:
DT_RowId - Add an ID to the TR elementDT_RowClass - Add a class name to the TR elementDT_RowData - Add HTML5 data- attributes to the TR element. This is an object of key / value pairs which are
assigned as data attributes to the TR element.This example below shows DT_RowId being used to add information to the table. In addition objects are used as the data source for the rows.
| First name | Last name | Position | Office | Start date | Salary |
|---|---|---|---|---|---|
| First name | Last name | Position | Office | Start date | Salary |
The Javascript shown below is used to initialise the table shown in this example:
$(document).ready(function() {
$('#example').dataTable( {
"processing": true,
"serverSide": true,
"ajax": "scripts/ids-objects.php",
"columns": [
{ "data": "first_name" },
{ "data": "last_name" },
{ "data": "position" },
{ "data": "office" },
{ "data": "start_date" },
{ "data": "salary" }
]
} );
} );
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.
The script used to perform the server-side processing for this table is shown below. Please note that this is just an example script using PHP. Server-side processing scripts can be written in any language, using the protocol described in the DataTables documentation.
