JavaScript: 让代码每分钟运行一次

小开

最佳答案

setInterval(function() {
// your code goes here...
}, 60 * 1000); // 60 * 1000 milsec

The function returns an id you can clear your interval with clearInterval:

var timerID = setInterval(function() {
// your code goes here...
}, 60 * 1000);


clearInterval(timerID); // The setInterval it cleared and doesn't run anymore.

A "sister" function is setTimeout/clearTimeout look them up.

If you want to run a function on page init and then 60 seconds after, 120 sec after, ...:

function fn60sec() {
// runs every 60 sec and runs on init.
}
fn60sec();
setInterval(fn60sec, 60*1000);

You could use setInterval for this.

<script type="text/javascript">
function myFunction () {
console.log('Executed!');
}


var interval = setInterval(function () { myFunction(); }, 60000);
</script>

Disable the timer by setting clearInterval(interval).

to call a function on exactly the start of every minute

let date = new Date();
let sec = date.getSeconds();
setTimeout(()=>{
setInterval(()=>{
// do something
}, 60 * 1000);
}, (60 - sec) * 1000);
