我尝试在几分钟内更改用户输入，但不幸的是，当我尝试这样做时，没有任何改变。
我所做的是将“remseconds”更改为 remminuts，并将数学也更改为“x 60”，但什么也没发生。
const container = document.querySelector('.counter');
const buttonsDiv = document.querySelector('.buttons');
const secInput = document.getElementById('seconds');
var seconds;
var remseconds;
var minuts;
var toCount = false;
function toSubmit() {
display('start');
remove('seconds');
remove('ok');
seconds = Number(secInput.value);
counting();
}
function display(e) {
document.getElementById(e).style.display = 'block';
}
function remove(e) {
document.getElementById(e).style.display = 'none';
}
function check(stat) {
if (stat.id == "start") {
display("stop");
remove("start");
toCount = true;
} else if (stat.id == "stop") {
display("continue");
remove("stop");
toCount = false
} else {
display("stop");
remove("continue");
toCount = true;
}
}
function count() {
if (seconds > 0) {
if (toCount == true) {
seconds--;
remseconds = seconds % 60;
minuts = Math.floor(seconds / 60);
if (minuts < 10) {
minuts = "0" + minuts;
}
if (remseconds < 10) {
remseconds = "0" + remseconds;
}
container.innerHTML = minuts + " : " + remseconds;
}
} else {
container.innerHTML = "DONE!";
buttonsDiv.style.opacity = "0";
}
}
function counting() {
remseconds = seconds % 60;
minuts = Math.floor(seconds / 60);
if (remseconds < 10) {
remseconds = "0" + remseconds;
}
container.innerHTML = minuts + " : " + remseconds;
setInterval(count, 1000);

我在这里编辑了几分钟的答案:js seconds countdown
获取分钟并在counting()中仅将其乘以x60转换为秒
const container = document.querySelector('.counter');
const buttonsDiv = document.querySelector('.buttons');
const minInput = document.getElementById('minutes');
var seconds;
var remseconds;
var minuts;
var toCount = false;
function toSubmit() {
display('start');
remove('minutes');
remove('ok');
minuts= Number(minInput.value);
counting();
}
function display(e) {
document.getElementById(e).style.display = 'block';
}
function remove(e) {
document.getElementById(e).style.display = 'none';
}
function check(stat) {
if (stat.id == "start") {
display("stop");
remove("start");
toCount = true;
} else if (stat.id == "stop") {
display("continue");
remove("stop");
toCount = false
} else {
display("stop");
remove("continue");
toCount = true;
}
}
function count() {
if (seconds > 0) {
if (toCount == true) {
seconds--;
remseconds = seconds % 60;
minuts = Math.floor(seconds / 60);
if (minuts < 10) {
minuts = "0" + minuts;
}
if (remseconds < 10) {
remseconds = "0" + remseconds;
}
container.innerHTML = minuts + " : " + remseconds;
}
} else {
container.innerHTML = "DONE!";
buttonsDiv.style.opacity = "0";
}
}
function counting() {
seconds = minuts*60;
remseconds = seconds % 60;
//minuts = Math.floor(seconds / 60);
if (remseconds < 10) {
remseconds = "0" + remseconds;
}
container.innerHTML = minuts + " : " + remseconds;
setInterval(count, 1000);
