这是我在这里问的第一个问题，因此，如果我没有遵循正确的准则，我会提前道歉。

基本上，我想做的是手动在Javascript中导航边区代码。导航本身运行良好，可以单击左侧或右侧，各部分将在轮播中无休止地滚动。但是，当用户离开该部分后，当我尝试将先前的页面scrollTop设置回0时，就会遇到问题。

如果我滚动浏览每个部分并向下滚动一点，那么当我返回首页并再次循环浏览它们时，它们似乎在scrollTop是否实际设置为0。

HTML正文：

<div class="Arrow" id="arrowLeft"></div>
<div class="Arrow" id="arrowRight"></div>
<section class="Page" id="page1"><div class="PageContent"></div></section>
<section class="Page" id="page2"><div class="PageContent"></div></section>
<section class="Page" id="page3"><div class="PageContent"></div></section>
<section class="Page" id="page4"><div class="PageContent"></div></section>
<section class="Page" id="page5"><div class="PageContent"></div></section>
<section class="Page" id="page6"><div class="PageContent"></div></section>
<section class="Page" id="page7"><div class="PageContent"></div></section>
<section class="Page" id="page8"><div class="PageContent"></div></section>
<script src="JavaScript/scroller.js"></script>

Javascript：

//initialising variables and populating arrays
var currentPage = 0;
var previousPage = 0;
var pages = document.getElementsByClassname("Page");
var sections = [];
for (i=0;i<pages.length;i++) {
    sections.push(pages[i]);
}
var pageOffSets = [0,100,200,300,400,-300,-200,-100];
var zOffSets = [0,-1,-2,-3,-4,-1];
for (i = 0;i<sections.length;i++) {
    sections[i].style.left = pageOffSets[i] + "vw";
    sections[i].style.zIndex = zOffSets[i];
}


//Navigate function
function slidePage(direction) {
        previousPage = currentPage;
    if (direction=="right") {
        currentPage+=1;
        if (currentPage>7) {
            currentPage = 0;
        }
        var hold = sections.shift();
        sections.push(hold);

         for (i=0;i<sections.length;i++) {
            sections[i].style.left = pageOffSets[i] + "vw";
            sections[i].style.zIndex = zOffSets[i];
        }
    }

    if (direction=="left") {
        currentPage-=1;
        if (currentPage<0) {
            currentPage = 7;
        }
        var hold = sections.pop();
        sections.unshift(hold);

         for (i=0;i<sections.length;i++) {
            sections[i].style.left = pageOffSets[i] + "vw";
            sections[i].style.zIndex = zOffSets[i];
        }
    }

    //!!!
    //This is the part that is supposed to set the scrollTop back to 0
    //!!!
    setTimeout(function(){
        sections[previousPage].scrollTop = 0;
    },1000);
}


//Event listeners for when the user clicks
document.getElementById("arrowLeft").addEventListener("click",function(){
    slidePage("left");
});
document.getElementById("arrowRight").addEventListener("click",function(){
    slidePage("right");
});

如果有人能指出我做错了什么，我将不胜感激。

修改： 如果需要，这是CSS：

  overflow-x: hidden;
  overflow-y: scroll;
}

  z-index: 1;
  width: 50px;
