After Effects Expression for replacing dots with commas

[stefanb78309260]

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!

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(".", ",")+" %";

Thank you very much, this code worked for me too.

In regex syntax the "." symbol is a special character that matches any character other than a line terminator. It should work if you escape it:

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

If you are trying to get a better handle on how regular expressions work an online regex tester like the one at https://regex101.com can be invaluable.

try this 

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

in German

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

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)
