如何停止倒计时功能然后运行

Question

我有这个倒计时功能，但是如果我想在运行模式下停止这个功能，我该怎么做？这样做将是

function GameCounter(){ 

     var sec = 6 
     $("#gamecounter span").html(sec) 

     var timer = setInterval(function() { 
      $('#gamecounter span').text(sec--); 
      if (sec == -1) { 
       newcards(); 
        clearInterval(timer); 
      } 
     }, 1000); 

}

的一种方式，

function GameCounter(){ 
     var sec = 6 
     $("#gamecounter span").html(sec) 
     var timer = setInterval(function() { 
      $('#gamecounter span').text(sec--); 
      if (sec == -1) { 
       newcards(); 
        clearInterval(timer); 
      } 
     }, 1000); 

     return timer; 
} 

//In the place where you calling the GameCounter() function. 
var timer = GameCounter(); 
//Call the below line to stop the interval at any point of time. 
clearInterval(timer);
