The Communauto Bookmarklet targets the Communauto website, a car pool sharing service located in Quebec, Canada. This mini-project was to me an introduction to bookmarklets, jquery and node.js (for testing).
The Communauto bookmarklet only does one thing: show the car numbers in the 'Availability Report' or 'Reservervation Grid' pages. These were recently removed and while it is still possible to know the numbers for available cars (by hovering the mouse over the link and analyzing the URI), this bookmarklet simplifies the task. It adds the car number next to the 'Select' links for every availability.
Hence there is no more guessing the car numbers. We can pick our favorite car just as before.
Go to this link and follow the instructions. It's dead simple. You just need to drag and drop a link to your bookmark browser bar. This will create the bookmarklet. The link to create it cannot be placed here as GitHub has severe restrictions on Javascript (i.e. this website is primarily used for source control and not as a web hosting solution).
Once you have the bookmarklet loaded in your bookmark bar, login to the Communauto page, do your operations as usual. But once you get in either the 'Availability Report' or 'Reservation Grid' pages, hit the 'Communauto Bookmarklet' button (or menu). This will execute Javascript code that will display the car numbers next to the 'Select' links. This only applies for cars that were not reserved yet, as the car number is not available (i.e. in the browser) for reserved cars.
Only Chrome has been tested with so far. Bookmarlets should work across all modern browsers though. If you have a bug or want to request support for your favorite browser, open an issue.
There are many improvement the Communauto website could use. If you think so too, and have an idea, open an issue.
