I have a dropdown list in a pdf with a couple of numbers, i want the text to change color depending on what number is choosen (1-5). I have "Space, 1, 2, 3, 4, 5" because i want the list to be blank when nothing is choosen (space).
The code down below gives me the function i want but the sad part is that the list is white when (space) is choosen and if i remove "if (v == 0){ event.target.textColor = color.white;" then i get a 0 instead of a blank box (space)
any suggestions?


var v = Number(this.getField("Dropdown2.1.0").valueAsString) ;
if (v == 0){
event.target.textColor = color.white;
} else if (v < 4){
event.target.textColor = color.black;
} else if (v > 3){
event.target.textColor = color.red;
}
event.value = v;

Didn't you post the same question in august ?

Why are you surprised you get a white color when the chosen value was 'space' ? That's what you programmed in the first line of the if.
Because I'm pretty sure that Number(this.getField("Dropdown2.1.0").valueAsString) returns zero if the field is blank or space.

I know zip, zero, nada, about javascript:x3:.
There's always the possibility to go and learn some... at least the basics. Given that you apparently need (or want?) to work with Javascript, it seems like the right thing to do.
But anyway, the problem should be clear, regardless from the language in question.
