How to get the current version of Chrome from the extension?

Question

I am making a user-agent switch for Chrome using the experimental WebRequest API, and I would like to display the current user agent.

To do this, I need to get the current version of Chrome, but I don’t know anything about this in the document, and I can’t access the page "chrome: // version" due to security reasons.

Do you have an idea to help me?

Answer 1

What about

window.navigator.userAgent 

on your original page?

Answer 2

You can always use the good old navigator object ( navigator.userAgent is an exact property, but it contains a lot of other information), it is available for extensions.

Answer 3

try

 function getChromeVersion(){ var match = window.navigator.userAgent.match(/Chrom(?:e|ium)\/([0-9\.]+)/); return match ? match[1] : null; }
