How do I open the JavaScript console in different browsers?

  • Web browsers provide a JavaScript console as part of their developer tools. This console is useful for the following reasons:

    • Errors and warnings that occur on a web page are logged into the console.
    • JavaScript commands for interacting with a web page can be executed in the console.

    What are the keyboard shortcuts for opening the console in different browsers?

    I went and made a tinyurl that links here, so if you need to instruct an audience of varied browser folks to open their javascript console... http://tinyurl.com/jscons

    • Mac : ++I

    In Firefox, it can opened in a separate window (and be global - not just for the current tab) by menu *Tools* → *Web Developer* → *Browser Console*.

    **F12** works in many browsers.

  • To indirectly reach the Console in Opera (checked on v9.6) the shortcut is Ctrl+Shift+i while on Safari 5 (on Windows) it is Ctrl+Alt+i

    I wish all the browser makers could get together to standardize the keyboard shortcuts.

    Update: It appears that the REPL tab under the Scripts tab in Opera Dragonfly in Opera 11 is similar to the Console option that was available in previous Opera versions.

    I did not found much documentation on REPL after a cursory search, except for this article which has an indirect reference.

    I tried this command in REPL with the Google home page open & it executed fine i.e. it hid the Google logo - document.getElementById('logo').style.visibility = 'hidden';

    CTRL + SHIFT + I will open the dev tools in Opera. But where is the JavaScript console? Where can I input JavaScript code and execute it?

    CTRL + ALT + I does nothing in my Safari 5 on Windows 7. Can you confirm that it works?

    That could be because you do not have the Develop menu option enabled. To activate this option, go to Edit > Preferences & in the Advanced tab enable the "Show Develop menu in menu bar" checkbox option.

    That was my problem. Stupid Apple disabling developer features by default. `:)` Thanks.

    Yes, that is it. I overlooked that REPL tab at the bottom LOL
