Help on getting elapsed time and elapsed distance into correct formatting

Former Member over 8 years ago

Hi, I'm playing around with data fields and hoping someone can help with this.

Trying to get formatting for elapsed time into m:ss from the info.elapsedtime data. Would also like it to support over the hr mark and going h:mm

And for distance I'm trying to get info.elapseddistance into 0.00 format.

Is there any samples out there i can look at? Also need to know if I need to account for null values at the beginning of an activity etc.

Thank you

Here's a simple function that does the conversion for time (call with ms - etime=toHMS(info.elapsedTime/1000); ):

function toHMS(secs) {
    	var hr = secs/3600;
    	var min = (secs-(hr*3600))/60;
    	var sec = secs%60;
    	if(hr!=0) {
    		return hr.format("%d")+":"+min.format("%02d")+":"+sec.format("%02d");
    	} else {
    		return min.format("%02d")+":"+sec.format("%02d");
    	}
    }

Here's a simple one for distance ( call is elapsedDistance=toDist(info.elapsedDistance);, and you need to do the formatting on the distance - it's in kms or miles ):

function toDist(value) {
		var ret=value/1000.0;
		if(Sys.getDeviceSettings().distanceUnits==Sys.UNIT_STATUTE) {
			ret=ret*0.621371;
		}
		return ret;
    }

Thank you sir. Would you also have one for average speed by chance?

Many thanks.

No problem (called with avgSpeed=toSpeed(info.averageSpeed); ) - value returned is mph or kph:

function toSpeed(value) {
		var ret=(value*3600.0)/1000.0;
		if(Sys.getDeviceSettings().paceUnits==Sys.UNIT_STATUTE) {       //you can use distanceUnits if you want
			ret=ret*0.621371;
		}
		return ret;
    }

OK thanks. In terms of calling this, I'd just make avgspeed and elapseddistance a variable? I'm a bit confused on the elapsed time one though with 'call with ms - etime=toHMS(info.elapsedTime/1000); ):

Yes - I put the converted value in a variable. For the code I pasted, I'm doing this in compute() in a data field, and then in onUpdate(), I display the value. One thing I didn't show is you want to check things like info.elapsedDistance for null, as many things in "info" can be null when first starting.

toHMS(info.elapsedTime/1000)
info.elapsedTime is in milliseconds, so info.elapsedTime/1000 converts that into seconds
