Copy-to-clipboard Bookmarklet

Create Bookmarklet (browser bookmark that executes Javsacript) to copy a given text to Clipboard.

This is the base javascript:

(function (text) {
  var node = document.createElement('textarea')
  var selection = document.getSelection()

  node.textContent = text
  document.body.appendChild(node)

  selection.removeAllRanges()
  node.select()
  document.execCommand('copy')

  selection.removeAllRanges()
  document.body.removeChild(node)
})('Text To Copy')

Minify it (you can use UglifyJS or any other) to get something like this:

!function(a){var b=document.createElement("textarea"),c=document.getSelection();b.textContent=a,document.body.appendChild(b),c.removeAllRanges(),b.select(),document.execCommand("copy"),c.removeAllRanges(),document.body.removeChild(b)}("Text To Copy");

Prefix it with javascript::

javascript:!function(a){var b=document.createElement("textarea"),c=document.getSelection();b.textContent=a,document.body.appendChild(b),c.removeAllRanges(),b.select(),document.execCommand("copy"),c.removeAllRanges(),document.body.removeChild(b)}("Text To Copy");

Then add it as a new bookmark, in the URL field:

You can do stuff like a "Copy page title" bookmarklet by simply passing document.title instead of the fixed string:

javascript:!function(a){var b=document.createElement("textarea"),c=document.getSelection();b.textContent=a,document.body.appendChild(b),c.removeAllRanges(),b.select(),document.execCommand("copy"),c.removeAllRanges(),document.body.removeChild(b)}(document.title);
