I need to extract the number of google plus likes with javascript

[Gulo]

Hello, I need to extract the number of google plus likes of some pages, for example bytes.com

the number is here:

https://plusone.google. com/u/0/_/%2B1/fastbutton?coun t=true&url=http ://www.bytes.com/


When you look at the html, you see much text and this:

window.__SSR = {c: 6.0 ,

the number after c: is 6.0, which is the number of likes.

But I don't know how to get this number..
I need it as javascript variable, because this will be used in other javascript functions of my website.

Small working example?
thanks

Small working example?

what have you tried?

[Gulo]

Usually I have used local Javascript functions. But in that case I don't even know how to save the html code of this website in a variable. Then I could try to extract this number.

The problem is, I don't know how to start.

the first thing to do is getting the page's source code in text form.
