Simple javascript bookmarklet browser icon

Bookmarklet

Code is based on the Bookmarklet module https://drupal.org/project/bookmarklet for Drupal by Benjamin Doherty. It's completely rewritten to work without dependencies like jQuery and jQuery UI. It also creates just plain iframe inside of the parent site to minimalize the probability of CSS conflicts.

Overview

This bookmarklet can be simply used at any site. Users can drag and drop the Bookmarklet button to his browser bar.

When he clicks at the button, an iframe is created inside of the DOM of the current site pointing to the given URL. Url, title and images from the current site are passed to the iframe as GET parameters.

Configuration

All you have to do is to configure the properties of settings object:

Property	Type	Description
url	string	full url to be opened in iframe
url_js	string	full url of bookmarklet.js file
css_iframe	string	css of iframe
css_overlay	string	css of page url
image	boolean	if we want to look for images contained in site
image_width	integer	minimal width of images
image_height	integer	minimal height of images

And here is the full code of the bookmarklet button (for details see example.html):

Drag and drop this <a href="javascript:
var bookmarklet;

(function () {
  var settings = {
    url: 'http://example.com',
    url_js: 'http://bookmarklet.loc/bookmarklet.js',
