    I cannot get the expression to ‘find a character in a string of text and replace it’ to work.

    I’ve been combing the web and trying all the examples & I either get a syntax error (invalid or unexpected token) or it doesn’t do anything.

    For example: I have a text layer with every character in the alphabet like this…


    I then apply this expression to the source text…

    text.sourceText.replace(/\d/gi, “test”)

    then nada. zip. nuthin.

    any ideas?

    Hi Pete,

    The regex you created will replace every digit (character class \d) with “test”, and there are no digits in your sourceText.

    if you wanted to replace the letter d, don’t use a backslash, if you wanted all non-digit characters, use \D

    still doesn’t work.

    I tried several permutations & still nothing

    Strange. This works for me…

    text.sourceText.replace(/d/gi, "test");

    result is abctestefghijklmnopqrstuvwxyz

    both in legacy extendscript and javascript modes.

    (edit: typos, and watch out for curly quotes that the websites loves to add, but invalidates javascript code)
