A snippet of JavaScript stored in a bookmark.

• 2018-02-22 on Pale Moon 27.6.2 (32-bit) on Linux.

• 2018-01-29 on Pale Moon 27.6.2 (32-bit) on Linux.

  • Also works via a keyword.

• (date not recorded) on Firefox (version not recorded)

  • Usable only by manually clicking the bookmark, and not usable with a keyword.

Howto / notes ∞

• Bookmarklets are JavaScript
• Debugging bookmarklets

• /* comments are allowed */

  • Nested comments are not possible.
  • // line comments are not allowed; bookmarklets are concatenated into one line.
• Be careful about using ();) with a semicolon (;). It's best to omit them entirely and use plain parentheses ()).

• Whitespace is largely ignored, so you can use line breaks and indentation.

Debugging bookmarklets ∞

• Chrome has F12 > Console

  • This is built-in.

• Firefox has something, but I haven't tested it.

Then you can paste your code in the console. I highly recommend you use alert()

An example:

alert(

window.location.href
+ "\n" +

'text'

)

prepend and reload ∞

• Tested 2021-06-02 on Brave Version 1.25.68 Chromium: 91.0.4472.77 (Official Build) (64-bit)

Save the current page in The Internet Archive Wayback Machine.

javascript:location.href='https://web.archive.org/save/'+window.location.host+window.location.pathname;

append and reload ∞

For MediaWiki, reset the page's cache ∞

Tested 2018-01-29 on Pale Moon 27.6.2 (32-bit) on Linux.

For the current page, append ?action=purge and reload. For MediaWiki, this forces a page cache reset.

Example:

example.com/foo.php
to:
example.com/foo.php?action=purge

Bookmarklet:

javascript:window.location+=%22?action=purge%22;

search-and-replace (edit and reload) ∞

search-and-replace ∞

From the WordPress editor, view the page: ∞

• Tested 2021-06-02 on Brave Version 1.25.68 Chromium: 91.0.4472.77 (Official Build) (64-bit)

From the WordPress editor, save the page in The Internet Archive Wayback Machine.

https://blog.spiralofhope.com/wp-admin/post.php?post=22505&action=edit
=>
https://web.archive.org/save/https://blog.spiralofhope.com/?p=22505

Bookmarklet:

javascript:location.href='https://web.archive.org/save/'+location.href.replace('wp-admin/post.php?post=','?p=').replace('&action=edit','')

If you use something like BlogText which has the edit URL appended with &classic-editor then you can use

javascript:location.href='https://web.archive.org/save/'+location.href.replace('wp-admin/post.php?post=','?p=').replace('&action=edit','').replace('&classic-editor','')

Obsoleted ∞

remember passwords for any site ∞

From 2010-01-12. This was obsoleted by a Firefox addon (whose name has not been noted).

Bookmark this. Then visit it before signing into one of those pesky sites.

  • You have to delete a character in your email address and re-type it for the password field to be filled again.

• www.cibconline.cibc.com

Does not work for:
