sourcetext: two expressions work well alone, but not together
Hello dear fellows,
I wrote two lines of code for a source text:
var txt = value;
txt.trim(); //removes whitespaces in front of text
txt.substr(0/37);//limits the string to 37 signs
Both expressions do what they should do when applied alone, but when I put them together,
the trim-expression seems not to function- whitespaces in front will not be cutted off. I tried to change to order of the two line as a test, but I still have no clue why does not work properly. I used the clamp-expression in an other situation, but I guess this is a wrong way. Does anyone have an idea to put them together or have a different solution? Thanks you so much!
Yours, Matthias

you’ve got the syntax wrong, each expression works fine on it’s own, but they RETURN a value, they don’t modify the existing value.
var txt = value;
txt.trim(); // removes whitespaces in front of text and returns the value - doesn't change the value of "txt" variable
txt.substr(0/37);//limits the ORIGINAL string to 37 signs and returns it again. Expressions uses this as the last returned valueTherefore you need to do something like this:
var txt = value;
txt = txt.trim(); //removes whitespaces in front of text
txt = txt.substr(0/37); //limits the string to 37 signs
txt;each expression will now update the value of the “txt” variable. hope that helps!

Yes, it works! Thank you so much for that help! It´s just mean that the expressions works seperately..I need to code for work and it´s so long ago that I did this. The brain is a sieve…or more precise,
my brain 🤣
