javascript - Jquery: setTimeout Timer and Corresponding High Score List Do Not Match -


this seems simple problem, can't seem find posts similar issue. i've written basic timer in jquery , starts , stops click of 2 buttons, , time @ stops passed high score list appears after. appears on high score list 0.01 seconds lower number on timer. there settimeout method cause this, or missing something?

fiddle here: https://jsfiddle.net/nbsteuv/j9otp5ya/

here's code i'm using timer:

function timer(){         if(starttimer=="true"){             settimeout(function(){                 i=i+0.01;                 $(".timer").html("<h1><center>"+ i.tofixed(2) + "</center></h1>");                 timer();             },10);         }; };

and here's code updates high score list:

$(".stopbutton").click(function(){         if(starttimer== "true"){             starttimer= "false";             updatescores(i);             darken(".space");         };     });  function updatescores(newscore){      if(newscore > highscore1){         var redscore="score1";         highscore5=highscore4;         highscore4=highscore3;         highscore3=highscore2;         highscore2=highscore1;         highscore1=newscore;     }else if(newscore > highscore2){         var redscore="score2";         highscore5=highscore4;         highscore4=highscore3;         highscore3=highscore2;         highscore2=newscore;     }else if(newscore > highscore3){         var redscore="score3";         highscore5=highscore4;         highscore4=highscore3;         highscore3=newscore;     }else if(newscore > highscore4){         var redscore="score4";         highscore5=highscore4;         highscore4=newscore;     }else if(newscore > highscore5){         var redscore="score5";         highscore5=newscore;     };      var highscoreplace1= "<div class='score' id='score1'><h1><center>" + highscore1.tofixed(2) + "</center></h1></div>";     var highscoreplace2= "<div class='score' id='score2'><h1><center>" + highscore2.tofixed(2) + "</center></h1></div>";     var highscoreplace3= "<div class='score' id='score3'><h1><center>" + highscore3.tofixed(2) + "</center></h1></div>";     var highscoreplace4= "<div class='score' id='score4'><h1><center>" + highscore4.tofixed(2) + "</center></h1></div>";     var highscoreplace5= "<div class='score' id='score5'><h1><center>" + highscore5.tofixed(2) + "</center></h1></div>";      $("#highscores").append(highscoreplace1, highscoreplace2, highscoreplace3, highscoreplace4, highscoreplace5, resetbutton);     $("#highscores").slidedown(1000);     $("#"+redscore).css("color", "red");     $(".resetbutton").click(function(){         gamereset();     }); };

full code, including variables , other functions, in fiddle.

it looks when click stop button, timer runs 1 more time, value of 'i' set value had when clicked (0.01 less). add 0.01 in click event stop button, updatescores(i+0.01); or perhaps find better way of doing altogether :). take @ satckoverflow answer: how create stopwatch using javascript?
