timers

I created the following function and calling it like this but the problem is i have to keep hitting the start button for the text area to change seconds.  I want to be able to click on start and it will count automatically but it isn't working now. Why is that?

      $("#btn1Start").click(function() {                  
            timer1 = setInterval($.do_time('hr1','min1','sec1'), 1000);
        });
      
      $("#btn2Start").click(function() {                  
            timer2 = setInterval($.do_time('hr2','min2','sec2'), 1000);
        });

      $("#btn3Start").click(function() {                  
            timer3 = setInterval($.do_time('hr3','min3','sec3'), 1000);
        });


//Timer JQuery function

(function($) 
{
	$.do_time = function(hrName,minName,secNam) {

		// parseInt() doesn't work here...
				hour = parseFloat($("#"+hrName).text());
				minute = parseFloat($("#"+minName).text());
				second = parseFloat($("#"+secNam).text());
				second++;
				
				
				
				if(second > 59) {
					second = 0;
					minute = minute + 1;
				}
				if(minute > 59) {
					minute = 0;
					hour = hour + 1;
				}
				
				$("#"+hrName).html("0".substring(hour >= 10) + hour);
				$("#"+minName).html("0".substring(minute >= 10) + minute);
				$("#"+secNam).html("0".substring(second >= 10) + second);
		
			
			}//End Doo time function
})(jQuery);

try using val() instead of html()

e.g.
$("#"+hrName).val("0".substring(hour >= 10) + hour);

it might work.. just an idea

put the function to execute as a string not directly.

so replace :
timer1 = setInterval($.do_time('hr1','min1','sec1'), 1000);
by :
timer1 = setInterval("$.do_time('hr1','min1','sec1')", 1000);

BTW, parseInt() does work, but because it is parsing a string with a leading zero i.e. "08", it treats it like an octal number. What you need to do is tell it to parse in base 10 using the less known second parameter if parseInt().

Why not also combine the H:M:S into one field?

FYI, there's a very simple, working example of this in the W3CSchools site: http://www.w3schools.com/js/tryit.asp?filename=tryjs_setinterval. That may help you understand the moving parts?

Now how would you make a function that would stop the timer.

leakim971PluritechnicianCommented:
Use clearInterval(id_of_setinterval) : http://www.w3schools.com/jsref/met_win_clearinterval.asp

$("#myStopButton1").click(function() { if(timer1) clearInterval(timer1) });
$("#myStopButton2").click(function() { if(timer2) clearInterval(timer2) });
$("#myStopButton3").click(function() { if(timer3) clearInterval(timer3) });

It worked how would you have a label that would calculate the total time of each timer running
