This just makes so many assumptions. The URL needs to be parsed properly.

@naomik: we are developers, we solve the tasks as they appear. The theoretics may theoretize for years, while we just provide a solutions for the business.

@naomik: treat it as a way to teach a person about how to ask better question. Well, I see your point, thank you for being such pedantic. Give me a second to check your answer. See you there. stackoverflow.com/a/17245542/251311 --- here is the first. Should I continue?

This won't match if the id is the only URL parameter, correct?

params = location.search.substring(location.search.indexOf('id')).split('&')[0]
id = params.substr(3)

This looks like the best answer here.

Note that this should be wrapped up into a function so that inside you can count the length of the key and dynamically populate that
substr argument.If it is always shipped in this exact order - then
url.match(/\d+/)
otherwise
url.match(/id=(\d+)/)

Sorry, but this is just asking for trouble.

@naomik: I'm following the task description. If it's not complete - it's not my problem.
zerkms
@naomik: please prove it's not the best? Please keep in mind that your criterias to determine the solution quality may not match mine.
zerkms
@naomik: you're making assumptions that such key may appear in the url. I'm used to using APIs that don't change randomly. Stop making assumptions please. If you want to prove my solution won't work - please ask OP to provide the URL my regex won't match

The second line of code is wrong, you are missing a
[1]. |
