expire time

I have the following code here but the question is I want the function $.do_time pass a value called expire time. So when button1Start and the expire time is getting close the color of the font would change.

$("#btn1Start").click(function () {
            timer1 = setInterval("$.do_time('timer1',"00:10:00","red")", 1000);
            $(this).attr("disabled", true);
      });

Given the code you've already got, you probably know how to add the parameters to the call and the function.

Javascript recognizes dates, but not times without dates, so you may have to convert back and forth to do the comparison... something like this code might help you get started

Then you'll have to set your attribute after the comparison "matches"

// converting time string to a date:
// from http://www.webdeveloper.com/forum/showthread.php?t=123460
var a = "10:15"
var b = toDate(a,"h:m")
alert(b);
function toDate(dStr,format) {
	var now = new Date();
	if (format == "h:m") {
 		now.setHours(dStr.substr(0,dStr.indexOf(":")));
 		now.setMinutes(dStr.substr(dStr.indexOf(":")+1));
 		now.setSeconds(0);
 		return now;
	}else 
		return "Invalid Format";
}

// changing color attribute
$(timerID).attr({ style: "color: red;" } );

I don't need dates at all. I just set the expire time to then if the timer ticker reaches that expired time then the text will change red.

This is a double post. Check https://www.experts-exchange.com/questions/26607756/expire-time-comparing-string.html

BTW, the function should check if the parameter "exptime" exists, because it could be optional.

@sam2912 you are right about checking the existence of the exptime variable.
but I do find my solution more elegant since it doesn't apply the color every second after exptime.

A better solution, in my opinion, would be this:

if(exptime){
	var temp = exptime.split(':');
	var expire = [];
	expire[0] = parseInt(temp[0],10);
	expire[1] = parseInt(temp[1],10);
	expire[2] = parseInt(temp[2],10);
	if( expire[0] == hour && expire[1] == minute && expire[2] == second){
		if(color){
			$('#' + timerID).css('color',color);
		} else {
			$('#' + timerID).css('color',"red");
		}
	}
}

ikbentomas this is true but lets say you had more then 3 buttons the expire time solution only works for 3 buttons . Correct me if i am wrong.
