Parent child editor

This example demonstrates Editor being used in a parent / child manner to edit groups of related items. The code and methodology is fully documented in this blog post. A similar post is also available showing parent / child editing in a child row.

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

var siteEditor = new DataTable.Editor({
	ajax: '../php/sites.php',
	fields: [
		{
			label: 'Site name:',
			name: 'name'
		}
	],
	table: '#sites'
});

var siteTable = $('#sites').DataTable({
	ajax: '../php/sites.php',
	columns: [

		{

			render: function (data) {
				return data.length;
			}
		}
	],
	layout: {
		topStart: {
			buttons: [
				{ extend: 'create', editor: siteEditor },
				{ extend: 'edit', editor: siteEditor },
				{ extend: 'remove', editor: siteEditor }

	},
	select: {

	}
});

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.
