copy

Since: Buttons 1.0.0

Copy table data to clipboard button.
Please note - this property requires the Buttons extension for DataTables.

Description

This button type serves as a proxy that will automatically detect if the copyHtml5 button can be used based on the browser's capabilities and the libraries available on the page.

This is provided as there is no API in HTML5 that allows a copy to clipboard action when clicking a button.

If the requirements of the copyHtml5 button are not satisfied, no button will be presented to the end user. For the requirements of each button type, please refer to its own documentation.

Options

This button can have the following options set in its configuration object to customise its actions and display, in addition to those options which are available for all buttons (e.g. buttons.buttons.text):

Name	Type	Default
`action`
Display a dialogue box that the user can use to copy table data to clipboard
`className`		buttons-copy
The button's class name. See `buttons.buttons.className` for details.
`copySuccess` Since: 3.1.2		true
Indicate if the message should be displayed or not when the copy is complete.
`customize` Since: 1.1.1		undefined
Function that can be used to modify the contents of the exported data. The function takes two parameters, the data as configured by the button and the button's configuration object. The value that the function returns is the value that will be used for the export. This can be particularly useful if you wish to add a company header or footer, description data or any other information to the exported data. As of Buttons 1.5.2 this function is passed three parameters: The data to be copied as a string The button configuration object A DataTables API instance for the table the button belongs to.
`exportOptions`		{}
Select the data to be gathered from the DataTable for export. This includes options for which columns, rows, ordering and search. Please see the `buttons.exportData()` method for full details - the object given by this parameter is passed directly into that action to gather the required data.
`fieldBoundary`
The character(s) used to enclose each field in the plain text representation of the table that is copied to the system's clipboard. This is automatically added at the start and end of each cell's data.
`fieldSeparator`		\t
The character(s) used to separate fields in the plain text representation of the table that is copied to the system's clipboard.
`footer`		false
Indicate if the table footer should be included in the exported data or not.
`header`		true
Indicate if the table header should be included in the exported data or not.
`messageBottom` Since: 1.4.0		*
Message to be shown at the bottom of the table, or the `caption` tag if displayed at the bottom of the table.
`messageTop` Since: 1.4.0		*
Message to be shown at the top of the table, or the `caption` tag if displayed at the top of the table.
`newline`		\n
The character(s) used to separate the lines of data. Please note that on Windows client's the default is `\r\n`. All other platforms have a default or `\n` only.
`text`		Copy
The button's display text. The text can be configured using this option (see `buttons.buttons.text`) or the `buttons.copy` option of the DataTables `language` object.
`title` Since: 1.4.0		*

Examples

DataTables initialisation: Use the copy button type to alias the HTML button options.:

new DataTable('#myTable', {
	layout: {
		topStart: {
			buttons: ['copy']
		}
	}
});

DataTables initialisation: Use the exportOptions to copy only the current DataTable page:

new DataTable('#myTable', {
	layout: {
		topStart: {
			buttons: [
				{
					extend: 'copy',
					text: 'Copy current page',
					exportOptions: {
						modifier: {
							page: 'current'
						}
					}
				}
			]
		}
	}
});
