如何在功能上停止间隔?

问题描述

我得到了功能，即间隔.我需要在完成时停止它.这是代码:

I got function, which is interval. And I need to stop it when it finishes. here is the code:

 function cut() {
    setInterval(function() {
       timer()
    }, 1000);
 }


 function timer() {

    seconds = seconds - 1;
    document.getElementById("timer1").innerHTML = minutes + ":" + seconds;
    if (seconds < 10) {
       document.getElementById("timer1").innerHTML = minutes + ":" + "0" + seconds
    }
    if (seconds <= 0) {
       clearInterval("cut()");


       //another code to be executed
    }
 }

我可以完全将此clearInterval用于函数吗?还是有另一种解决方案呢?

can I use this clearInterval for function at all? or there is another solution for doing that?

谢谢:)

推荐答案

您必须保留对 setInterval()返回的句柄的引用，然后将其传递给 clearInterval()像这样:

You have to keep a reference to the handle returned from setInterval() and then pass it to clearInterval() like so:

var cutHandle;

function cut() {
    cutHandle = setInterval(timer, 1000);
}

function timer() {
    seconds = seconds - 1;
    var timer = document.getElementById("timer1");
    timer.innerHTML = minutes + ":" + seconds;
    if (seconds < 10) {
        timer.innerHTML = minutes + ":" + "0" + seconds
    }
    if (seconds <= 0) {
        clearInterval(cutHandle);
        //another code to be executed
    }
}
