Targeting dynamic text fields from within a function (JS)

[michaelh_cdk]

I have the function below, it runs on a timer every second. The idea is to update the 3 dynamic text fields with the current hour, minute and second.  If the code inside the function is run on the root timeline, it's fine. But once placed within a function, the "this." parts that target the dynamic text fields (near the end of the function) no longer work. I guess the text fields are not visible to the function?   I've tried removing "this". I've tried adding "window." or "parent." but to no success. What targets *anything* on the root timeline from within a function?

function updatetime() {
totalmilli = totalmilli-1000;
console.log('Remaining milliseconds = ' + totalmilli)
// 1- Convert to seconds:
seconds = totalmilli / 1000;
// 2- Extract hours:
hours = parseInt( seconds / 3600 ); // 3,600 seconds in 1 hour
seconds = seconds % 3600; // seconds remaining after extracting hours
// 3- Extract minutes:
minutes = parseInt( seconds / 60 ); // 60 seconds in 1 minute
// 4- Keep only seconds not extracted to minutes:
seconds = seconds % 60;
// Handle display of the above.
if (seconds< 10){
seconds = "0"+seconds;
}
if (minutes< 10){
minutes = "0"+minutes;
}
if (hours< 10){
hours = "0"+hours;
}
console.log(hours+" hours and "+minutes+" minutes and "+seconds+" seconds!" );
this.dyn_hours.text = hours;
this.dyn_minutes.text = minutes;
this.dyn_seconds.text = seconds;
}

Ah, I eventually found the right thing to ask Google. Hurrah. The new equivalent of _root is exportRoot.

So 

exportRoot.dyn_hours.text = hours;

works.
