要在执行函数时停止它，请使用 −

document.getElementById().addEventListener().

示例

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Document</title>
<link rel="stylesheet" href="//code.jquery.com/ui/1.12.1/themes/base/jquery-ui.css">
<script src="https://code.jquery.com/jquery-1.12.4.js"></script>
<script src="https://code.jquery.com/ui/1.12.1/jquery-ui.js"></script>
</head>
<body>
<button type="button" id="call">Call the function</button>
<button type="button" id="halt">Stop the function execution </button>
<script>
   document.getElementById("call").addEventListener("click", callFunction);
   document.getElementById("halt").addEventListener("click", haltFunction);
   var timeValue = null;
   function callFunction() {
      timeValue = setInterval(function() {
         console.log("The call() is being executed....");
      }, 1000);
   }
   function haltFunction() {
      clearInterval(timeValue);
   }
</script>
</body>
</html>

要运行上述程序，请保存文件名为anyName.html(index.html)，然后右键单击该文件并选择在 VS 代码编辑器中使用实时服务器打开选项。
