How to: Add a Copyright Notice to Copied Text

This is not a big magic thing. I just simply running a JavaScript function for this magic. This function grabs the copied content, insert a copyright notice, and then add to the clipboard. Thanks to c.bavota for his great script. According to the developer, this function will work for all major browsers except Internet Explorer.

Here is the Magic.Just copy this script and paste it into the “<head> </head>” tags.

Copyright ©";
var copytext = selection + pagelink;
var newdiv = document.createElement('div');'absolute';'-99999px';
newdiv.innerHTML = copytext;
window.setTimeout(function() {
document.oncopy = addLink;
