It's a good idea to learn some JavaScript.
var
myCommaSeparatedInputString = '2,5,7,9,2,4,6,5,9,8,7,4,12,5',
myUniqueOutputString = Array.from(new
Set(myCommaSeparatedInputString.split(','))).join()
;
We can test it directly with devtools in Firefox (F12) -> JS-Environment.
console.clear();
var
myCommaSeparatedInputString = '2,5,7,9,2,4,6,5,9,8,7,4,12,5',
myUniqueOutputString = Array.from(new
Set(myCommaSeparatedInputString.split(','))).join()
;
console.log(myCommaSeparatedInputString);
console.log(myUniqueOutputString);
Output:
21:13:38.354 Konsole wurde geleert. Scratchpad/1:1
21:13:38.354 2,5,7,9,2,4,6,5,9,8,7,4,12,5 Scratchpad/1:8:1
