Javascript 如何停止/清除间隔

我正试图停止/清除间隔，但出现了一个错误

代码如下：

   function play(){
      function sequencePlayMode() {
         var arg1;//some arguments
         var arg2;//some arguments
         changeBG(arg1,arg2);//here is function that changes the background
      }

     var time = 5000;
     var timer = setInterval(sequencePlayMode, time);//this starts the interval and animation

    }


    function stop(){
       var stopPlay  = clearInterval(sequencePlayMode);//here i'm getting error "sequencePlayMode is not defined"
    }


    $("#startAnimation").click(function(){
            play();
    });

    $("#stopAnimation").click(function(){
           stop();   
    });

有人能帮我吗？

您需要使用存储函数的变量，而不是调用它的函数。您还需要使其他函数可以访问该变量

(function () {  

   var timer;  //define timer outside of function so play and stop can both use it
   function play(){
      function sequencePlayMode() {
         var arg1;//some arguments
         var arg2;//some arguments
         changeBG(arg1,arg2);//here is function that changes the background
      }

     var time = 5000;
     timer = setInterval(sequencePlayMode, time);//this starts the interval and animation

    }


    function stop(){
       var stopPlay  = clearInterval(timer);
    }


    $("#startAnimation").click(function(){
            play();
    });

    $("#stopAnimation").click(function(){
           stop();   
    });

})();

间隔定时器；试试这个可能的@epascarello副本-当然……我真傻……我怎么会错过这个！非常感谢
