cytoscape-clipboard

Description

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

Here is a demo:

API

```javascript 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

```javascript 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) {}   

}; ```
