ZeroClipboard is a JavaScript interface and integration library designed to copy text to the system clipboard. It functions as a bridge between JavaScript and a hidden Adobe Flash movie runtime to achieve system-level clipboard access.
The project specifically bypasses legacy browser security restrictions that prevent direct clipboard writes. It enables clipboard functionality for older web browsers that lack modern JavaScript clipboard APIs by routing text operations through an invisible Flash object.
The library provides the necessary tools to develop web page utilities where visitors can copy specific snippets of text or codes via a single-click interface.
