  • Hi,

    I have develop my first extension following the guide lines of the opera for developers 🙂
    But i have the following example problem that i need help.

    I want to inject/alter javascript code in all pages where that particular javascript is present.

    1. The user types a site
    2. The extension checks if the javascript code is present
    3. If exists alters the javascript code and continue loading the page

    Note: The code alteration is setup of the first time the extension is installed.

    If anyone can help me out on this one, Thanks

  • I think you can use the webRequest API to detect it. For example, take a look at this SO answer here

  • Thanks for all the help but i got even more confuse.

    The purpose was to build a tool that will switch the adsense affiliate code to any PUB-ID you want and every time a advertising was loaded it will be credit to that account. Usefull for Cyber Cafes owners.
