cytoscape-clipboard

Description

A Cytoscape.js extension to provide copy-paste utilities, distributed under The MIT License.

Here is a demo:

API

    var cy = cytoscape({...});

    var cb = cy.clipboard(options);

cy.clipboard(options) Initializes extension & sets options.

cb.copy(eles [, id]) Copies eles and returns id of operation. If id is not specified, it will be assigned automatically.

cb.cut(eles [, id]) Cuts eles, which copies and removes them. If id is not specified, it will be assigned automatically.

cb.paste([id]) Pastes the copied elements which has id. If id is not specified, it will have the last operation's id.

Default Options

var options = {

	// The following 4 options allow the user to provide custom behavior to
	// the extension. They can be used to maintain consistency of some data
	// when elements are duplicated.
	// These 4 options are set to null by default. The function prototypes
	// are provided below for explanation purpose only.
	
	// Function executed on the collection of elements being copied, before
	// they are serialized in the clipboard
	beforeCopy: function(eles) {},
	// Function executed on the clipboard just after the elements are copied.
	// clipboard is of the form: {nodes: json, edges: json}
	afterCopy: function(clipboard) {},
	// Function executed on the collection of elements being cut, before
	// they are serialized in the clipboard
	beforeCut: function(eles) {},
	// Function executed on the clipboard just after the elements are cut.
	// clipboard is of the form: {nodes: json, edges: json}
	afterCut: function(clipboard) {},
	// Function executed on the clipboard right before elements are pasted,
	// when they are still in the clipboard.
	beforePaste: function(clipboard) {},
	// Function executed on the collection of pasted elements, after they
	// are pasted.
	afterPaste: function(eles) {}	
};
