    Smile JavaScript question

    Hello. Sorry potentially about this question. On a computer I use..I can first go to the 'tools' command button...then scroll down to 'developer tools'. When I get there a particular screen shows up. It displays the javascript encoded on the the particular 'page' I am viewing. Is it possible to 'alter' the code that already exists for a page? I can not seem to alter what I am viewing at all.

    Can you create javascript by 'typing' in script when this screen is displayed? Or do you have to use 'notepad'?

    Thanks for any and all responses
    Bye

    My assumption is that you are looking at the "View Source" screen display.

    You cannot modify this screen and re-execute the script.
    You can however copy the source, paste it to a new textfile with NotePad (or other text editor)
    save the modified code and then execute it from your browser's 'open file' command.

    That also assumes there are not any external files being accessed.
    If there are, they need to be copied as well if they are not referenced with a complete URL.

    I think he means Developer Tools (F12 in IE).

    Is it possible to 'alter' the code that already exists for a page? No, no and no!

    He means (say) change price = 100 to price = 1 or something.

    All the code given in this post has been tested and is intended to address the question asked.
    Unless stated otherwise it is not just a demonstration.

    in firefox's tools>web developer there is a javascript scratch pad where you can enter javascript and see what changes it makes to the page. It will only affect the local version of the page for the length of the browser session, though, of course.
