# Editor example Cancel button

This example shows how the `formButtons` option of the `create`, `edit` and `remove` buttons can be used to add a cancel button to the Editor form. The value given is passed directly to the `buttons()` method, so allowed values there are also accepted by `formButtons`.

In this example we make use of that ability to provide a simple submit button (`buttons()` will automatically assign a submit action to string values) and a button that will call the `close()` method to cancel the current action.

Name | Position | Office | Extn. | Start date | Salary
--- | --- | --- | --- | --- | ---
Name | Position | Office | Extn. | Start date | Salary

- JavaScript
- HTML
- CSS
- Ajax
- Server-side script

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

`const editor = new DataTable.Editor({ ajax: '../php/staff.php', fields: [ { label: 'First name:', name: 'first_name' }, { label: 'Last name:', name: 'last_name' }, { label: 'Position:', name: 'position' }, { label: 'Office:', name: 'office' }, { label: 'Extension:', name: 'extn' }, { label: 'Start date:', name: 'start_date', type: 'datetime' }, { label: 'Salary:', name: 'salary' } ], table: '#example' }); const table = new DataTable('#example', { ajax: '../php/staff.php', columns: [ { data: null, render: (data) => data.first_name + ' ' + data.last_name }, { data: 'position' }, { data: 'office' }, { data: 'extn' }, { data: 'start_date' }, { data: 'salary', render: DataTable.render.number(null, null, 0, '$') } ], layout: { topStart: { buttons: [ { extend: 'create', editor: editor, formButtons: [ { text: 'Cancel', action: function () { this.close(); } }, 'Create' ] }, { extend: 'edit', editor: editor, formButtons: [ { text: 'Cancel', action: function () { this.close(); } }, 'Edit' ] }, { extend: 'remove', editor: editor, formButtons: [ { text: 'Cancel', action: function () { this.close(); } }, 'Delete' ] } ] } }, 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:

`a.marginLeft { margin-left: 1em; }`

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.
