Options - week numbers

It can often be useful to see at a glance what week of the year a week falls into - this option is provided in the datetime calendar picker through the showWeekNumber option which is specified as part of an opts (i.e. options) object.

This example shows the week number enabled for the date picker using a simple ISO8601 date format.

The Javascript shown below is used to initialise the table shown in this example:

var editor = new DataTable.Editor({ ajax: '../php/dates.php', fields: [ { label: 'First name:', name: 'first_name' }, { label: 'Last name:', name: 'last_name' }, { label: 'Registered date:', name: 'registered_date', type: 'datetime', opts: { showWeekNumber: true } } ], table: '#example' }); $('#example').DataTable({ ajax: '../php/dates.php', columns: [ { data: 'first_name' }, { data: 'last_name' }, { data: 'updated_date' }, { data: 'registered_date' } ], layout: { topStart: { buttons: [ { extend: 'create', editor: editor }, { extend: 'edit', editor: editor }, { extend: 'remove', editor: editor } ] } }, select: true });
const editor = new DataTable.Editor({ ajax: '../php/dates.php', fields: [ { label: 'First name:', name: 'first_name' }, { label: 'Last name:', name: 'last_name' }, { label: 'Registered date:', name: 'registered_date', type: 'datetime', opts: { showWeekNumber: true } } ], table: '#example' }); new DataTable('#example', { ajax: '../php/dates.php', columns: [ { data: 'first_name' }, { data: 'last_name' }, { data: 'updated_date' }, { data: 'registered_date' } ], layout: { topStart: { buttons: [ { extend: 'create', editor: editor }, { extend: 'edit', editor: editor }, { extend: 'remove', editor: editor } ] } }, select: true });

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 interaction for this demo is shown below. This server uses PHP, so the PHP script is shown, however our download packages include the equivalent script for other platforms, including .NET and Node.js. Server-side scripts can be written in any language, using the protocol described in the Editor documentation.
