Bookmarklet editor

In a nutshell, bookmarklets are small little applications you can place as browser’s bookmark bar, and they each perform a specific function, depending on what they are coded for.

Bookmarklets are usually written in JavaScript, and they are extremely easy to install/remove. To install a bookmarklet, all you need to do is drag them to your bookmark toolbar.

If you want to test with a bookmarklet and you don't have one available, here is one that increases the font size of all elements by 25%. Copy the code into the textarea above.

javascript:(function()%7Blet%20elms%20%3D%20%5B...document.querySelectorAll('*')%5D%3B%0A%0Afor%20(let%20elm%20of%20elms)%20%7B%0A%20%20%20%20let%20cs%20%3D%20getComputedStyle(elm)%3B%0A%20%20%20%20let%20fs%20%3D%20cs%5B'font-size'%5D%3B%0A%20%20%20%20elm.oriSize%20%3D%20parseFloat(fs)%3B%0A%7D%0A%0Afor%20(let%20elm%20of%20elms)%20%7B%0A%20%20%20%20let%20fs%20%3D%201.25%20*%20elm.oriSize%3B%0A%20%20%20%20elm.style.fontSize%20%3D%20fs%20%2B%20%22px%22%3B%0A%7D%7D)()

And here is one that looks for the current website in the Wayback Machine archive.

javascript:(function()%7Bwindow.location%3D'http%3A%2F%2Fweb.archive.org%2Fweb%2F*%2F'%20%2B%20document.URL%7D)()

And one that pops up the content of the cookies associated with the current website.

javascript:(function()%7Bdocument.cookie%3D''%3Bfunction%20hjK(S4p)%7BD3p%3D%2F%3B%20%2Fg%3Breturn%20S4p.replace(D3p%2C%20'%3Cbr%3E%3Cbr%3E')%3B%7Dif(document.cookie.length%3C1)%7Balert('No%20cookie%20from%20this%20site!')%7Delse%7Bwith((na%3Dopen(''%2C''%2C'')).document)%7Bwrite(hjK('Cookie%20for%20'%2Bdocument.title.link(window.location.href)%2B'%2C%20dd.%20'%2Bnew%20Date()%2B'%3Chr%3E'%2Bdocument.cookie))%3Bclose()%7D%7D%7D)()
