Bug 396609

I can't get this working on Firefox. But Bookmarklets are working at all in Falkon.
Here is an example you can try on the current page:

================== EXAMPLE BOOKMARKLET ======================

javascript:mt=document.getElementsByTagName('meta')[0].getAttribute('content');if(mt){alert('Content of the current page is: '+mt)};

=============================================================

The translation bookmarklet still doesn't work for me in Falkon 3.1.0. The_assassin's example works fine.

Hello,
There is probably some mistake in that code (it is old).

1. As mentioned, you need to use https otherwise it will work only on http sites
2. we can get rid or 'scri'+'pt' and replace it with 'script' (it is easier to read)
3. And here comes the obstacle
 - Remove: v.style.display='none';
   It will display some selectbox to manually trigger translating
 - Use the select box to trigger the translating, the translate bar will appear
 - After this was done, when you use this bookmarklet again on the same tab it will display the selectbox and also the translate toolbar and loads a lots of scripts
4. So I presume it is some kind of error with javascript or some execution thing...
5. The workaround is not so bad...

====

javascript:%7Bd=document;b=d.body;o=d.createElement('script');o.setAttribute('src','https://translate.google.com/translate_a/element.js?cb=googleTranslateElementInit');o.setAttribute('type','text/javascript');b.appendChild(o);v=b.insertBefore(d.createElement('div'),b.firstChild);v.id='google_translate_element';p=d.createElement('script');p.setAttribute('type','text/javascript');p.text='function%20googleTranslateElementInit()%7Bnew%20google.translate.TranslateElement(%7BpageLanguage:%22%22%7D,%22google_translate_element%22);%7D';b.appendChild(p);%7D

I confirm that this workaround works as described, and here is an interesting observation: once this workaround has been applied and a page has been translated, the original bookmarklet works now on any page on the same site, but only as long as I don't click "Show original" in the translation bar.
