After Effects Expression for replacing dots with commas

  • January 29, 2022

Hello all.

 

I have the following expression for my source code: 

effect("Einstellungen für Schieberegler")("Schieberegler").value.toFixed(1)+" %";

 

Unfortunately, the digits after the comma are separated by a dot. Since I work in Germany, I would like to have the place after the comma separated by a comma. 

 

Unfortunately, this does not work as an addition:

replace (".",",");

 

Can anyone help me?

 

Thank you very much!

    Correct answer OussK

    Also this one is better if you want to automatically add comma for every 3 digits 

     

     

    num = effect("Slider Control")("Slider").value.toFixed(1).toString().replace(".", ",")+"%";
function addCommas(x) { return x.toString().replace(/\B(?=(\d{3})+(?!\d))/g, ","); }
addCommas(num)

     

     

     

    num =effect("Einstellungen für Schieberegler")("Schieberegler").value.toFixed(1).toString().replace(".", ",")+" %";
function addCommas(x) { return x.toString().replace(/\B(?=(\d{3})+(?!\d))/g, ","); }
addCommas(num)

    You'll want to use toLocaleString() to solve such issues related to international numbering systems. 

    I've started writing a series of short tutorials on using Modern Javascript in After Effects Expressions. These are part of my Advanced Course on Developing Advanced Intelligent Design Assets - these are start of the moment AE Templates/MoGRTs.

    I'll add more topics in the days and weeks ahead. Quite a few will also make it into my upcoming AE Script, AeXpressions NotePad - I hope it's OK to share this teaser/snippet.

    try this 

    effect("Slider Control")("Slider").value.toFixed(1).toString().replace(".", ",")+"%";

    in German

    effect("Einstellungen für Schieberegler")("Schieberegler").value.toFixed(1).toString().replace(".", ",")+" %";

        Make sure your project's expression engine is Javascript (which you can do in File > Project Settings > Expressions, then use this expression:

        text.sourceText.split('.').join(',');

         

        Someone who knows Javascript better than me can explain why what you would usually use:

        text.sourceText.replace(/./g, ",")

        replaces all the characters and there's probably a simple character addition to tell the script to only select '.' and not take it to mean all characters.

          Dear ShiveringCactus
          Thank you very much for your help. Unfortunately it doesn't work, although I checked before that my file uses Java script (thanks for the tip). The result was that the whole number was replaced by the word "numbers".
          However, OussK's idea worked:
          effect("Slider settings")("Slider").value.toFixed(1).toString().replace(".", ",")+" %";
