I am trying to turn an old javascript program of mine into a service on a mac using automator. When I use my Code, it doesn't work. I have checked what I can, and I have found that the most basic issue I encounter is that the .length property from javascript does not work. This simple program doesn't return what it should. It returns nothing:
function run(input) {
var ina = 'hello';
var newn = ina.length;
return newn;
}
Your code returns 5.
input is an array of 0 elements. Not of much use in script editor. When run from a command line it is the parameters.
As a side note run is the run handler for all AppleScript (including JXA), so you would not call function run. It is called for you.
UPDATE:
In automator, The result (5) is sent to the next automator task. You can do a "Set Value of Variable" right after you do "Run JavaScript" with your script to capture the 5.
