How to find a specific javascript code within pages?

[g52010]

Say .. I must find a specific javascript code within pages (*.php,*.html,*.asp etc)Code: [ Select ]How widely used is this key/value pair?doing a simple google for javascript advertising_client reveals that it's not a very common variable, as it returns no results. I think you're going to be hard pressed to find this. May I ask what you're trying to find? Maybe there's another approach.Would you like to search that code inside a specific website or to search what sites around the internet have that code inside their pages?I'm sorry if my question was not clear, since English is not my primary language I'm searching what pages in internet have that code inside their pages.The reason is, my friend has many FREE websites .. too many until he himself forgot that sites. The only thing he remember is that he always place a FREE counter or Advertisement in all those FREE websites.He also has lost one email account, which is provided by a paid domain that now is taken by somebody else.I would like to track those FREE website by searching that FREE counter code or Advertisement code, which is in Javascript.Again, english is not my primary language I don't think google texitifes javascript, so it's not possible to match that code.An alternative way could be to scan your friend's e-mail box and search for the e-mails received from that free hosting service.better to type the description or title of the code that you want and not the code it self.
