清除设定间隔

Question

 setInterval(function hello() {
  console.log('hello world');
  return hello;
}(), 6000);

如何清除间隔，我尝试添加变量间隔

var i =0;
var interval = setInterval(function hello() {
  console.log('world');
  if(++i == 3) clearInterval(interval);
  return hello;
}(), 5000);

但是没有用。感谢您的帮助。

Answer 1

clearInterval() 当然有效。您在以下代码行中有错误：

    }(), 5000);
   //^^ remove () as this is not IIFE

Answer 2

var i =0;
var interval = setInterval(function hello() {
  console.log('world');
  if(++i == 3) clearInterval(interval);
  return hello;
}(), 5000); // notice those parenthesis

您应该将处理程序传递给 setInterval() 而不是就地调用它，
