How to extract a JS variable using scan or match function in ruby?

Question

I get the content (source) of a webpage by using faraday in ruby. I want to extract a JS variable in the source code obtained with faraday. The JS variable is written like this :

argTab["labelExample"] = "theThingIWant";

I want to do this in ruby (framework rails).

How about this:

/\w+\[\"\w+\"\]\s\=\s\"(\w+)\"\;/.match(f)[1]

where f is your source string? It's important to note that this only escapes double quotes, but it could easily be improved to allow single or double quotes.
