JavaScript for iPhone to open in Safari from non-default iOS browser

Question

"googlechrome://www.lego.com" opened in mobile Safari will switch to Google Chrome iOS app to open the URL. This allows for scriptlets like the one below, which allows you to open the current page in Google Chrome iOS app, switching from mobile Safari:

(function()%7Bif(document.location.href.indexOf('http')===0)document.location.href=document.location.href.replace(/%5Ehttp/,'googlechrome');%7D)();

My question is, can the reverse be done? I tried "safari://www.lego.com", and it is simply an invalid URL. Can you make a scriptlet which switches from Google Chrome to mobile Safari to open the current page.

Answer 1

The answer is yes. Courtesy or MacStories (http://www.macstories.net/tutorials/chrome-for-ios-send-a-webpage-back-to-safari-via-bookmarklet/), I found this code:

window.location='googlechrome-x-callback://x-callback-url/open/?url='+encodeURIComponent(location.href)+'&x-source=Safari&x-success='+encodeURIComponent(location.href);

Execute that code, go to your homescreen, reopen Chrome, and there's a magical back button to go back to Safari. This may not be exactly what you want, but it works... Kink of.

Good luck!

It seems that the functionality to do this has broken. Thank you!
