对于一个项目,我需要每隔7秒向下滚动一页,如果它到达底部,它会向上滚动。那一遍又一遍。
到目前为止我已经做到了它每7秒滚动一次。如果触摸到底部,我尝试了20个选项滚动到顶部,但没有一个工作。

答案 0 :(得分:0)
这应该有效:
function countdown() {
var count = 8;
var timerId = setInterval(
function() {
count--;
console.log(count);
document.getElementById("timer").innerHTML = count;
if(count == 0) {
count = 8;
if (document.documentElement.scrollTop >= document.documentElement.scrollHeight - document.documentElement.offsetHeight) {
window.scrollTo(0, 0);
}
else {
window.scrollBy(0, 685);
}
}
if(count == 1) {
}
if(count == 2) {
}
}, 1000);
}
