问题描述
我想通过单击按钮停止计时器，但是我找不到确切的方法.我试图通过 clearInterval()停止计时器，但不确定是否调用正确.
I want to stop a timer by clicking a button but I can't find the exact way. I've tried to stop a timer by clearInterval() but I'm not sure if it is called properly.
这是我的工作代码.
<html> <head> <title>Bootstrap</title> <meta charset="utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1"> <link rel="stylesheet" type="text/css" href="setest_style.css"> <link href="cdn.bootcss/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet"> <link rel="stylesheet" href="cdnjs.cloudflare/ajax/libs/font-awesome/4.7.0/css/font-awesome.min.css"> <script src="ajax.googleapis/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <script type="text/javascript"> var sec = 0; function pad(val) { return val > 9 ? val : "0" + val; }; setInterval( function(){ $("#seconds").html(pad(++sec%60)); $("#minutes").html(pad(parseInt(sec/60,10))); }, 1000); function myStopFunction() { clearInterval(sec); } </script> </head> <body> <div class="quiz-time"> <div class="timer"> <span id="minutes">00</span>:<span id="seconds">00</span> </div> <button href="#" id="show-explanation" class="button1" onclick="myStopFunction()">Stop</button> </div> </body> </html> 推荐答案
将设置的间隔作为变量，然后使用清除间隔
take that set interval into a variable then use clear interval
var myInterval = setInterval( function(){ $("#seconds").html(pad(++sec%60)); $("#minutes").html(pad(parseInt(sec/60,10))); }, 1000); function myStopFunction() { clearInterval(myInterval); }更多推荐
