javascript - jQuery Countdown Timer for Games -

i need solid countdown timer queeze game, not easy hack.

i tried create own timer, sense fragile hacking:

var counter = 10; var timer = null; function countdown(){ if (counter == 10) { $(".time_box").html(counter); } if (counter <= 0) { stopinterval(); } else { counter--; $(".time_box").html(counter); } } function reset() { clearinterval(timer); counter=0; } function startinterval() { $(".time_box").html(counter); timer= setinterval("countdown()", 1000); } function stopinterval() { clearinterval(timer); }

any ideas security improvments?

javascript not place security, 1 recommendation give cut down risk of user intervening encapsulate code cannot modified outside of object.

for illustration @ moment run next in browser console gain myself time:

counter = -99999

however if encapsulate logic counter isn't exposed wouldn't possible.

var myfunction = function(){ var counter = 10; var timer = null; function countdown(){ if (counter == 10) { $(".time_box").html(counter); } if (counter <= 0) { stopinterval(); } else { counter--; $(".time_box").html(counter); } } function reset() { clearinterval(timer); counter=0; } function startinterval() { $(".time_box").html(counter); timer= setinterval(countdown, 1000); } function stopinterval() { clearinterval(timer); } homecoming { startinterval: startinterval } }();

then phone call next start count down:

myfunction.startinterval();

now phone call counter in browser console wouldn't work, , neither myfunction.counter.
