我正在创建一个有两个我想然后div自动滚动，并保持在div的高度是固定的滚动证明部分
我不知道为什么，但是在我的代码中只有一个div移动，另一个没有。
我已经创建了一个div并应用了JavaScript用于自动滚动，但是JavaScript对第二个div不起作用。

ScrollRate = 100;

function scrollDiv_init() {
  DivElmnt = document.getElementById("MyDivName");
  ReachedMaxScroll = false;

  DivElmnt.scrollTop = 0;
  PreviousScrollTop = 0;

  ScrollInterval = setInterval("scrollDiv()", ScrollRate);
}

function scrollDiv() {
  if (!ReachedMaxScroll) {
    DivElmnt.scrollTop = PreviousScrollTop;
    PreviousScrollTop++;

    ReachedMaxScroll =
      DivElmnt.scrollTop >= DivElmnt.scrollHeight - DivElmnt.offsetHeight;
  } else {
    ReachedMaxScroll = DivElmnt.scrollTop == 0 ? false : true;

    DivElmnt.scrollTop = PreviousScrollTop;
    PreviousScrollTop--;
  }
}

function pauseDiv() {
  clearInterval(ScrollInterval);
}

function resumeDiv() {
  PreviousScrollTop = DivElmnt.scrollTop;
  ScrollInterval = setInterval("scrollDiv()", ScrollRate);
}

ScrollRate2 = 100;

function scrollDiv_init_2() {
  DivElmnt2 = document.getElementById("MyDivName2");
  ReachedMaxScroll2 = false;

  DivElmnt2.scrollTop2 = 0;
  PreviousScrollTop2 = 0;

  ScrollInterval2 = setInterval("scrollDiv2()", ScrollRate2);
}

function scrollDiv2() {
  if (!ReachedMaxScroll2) {
    DivElmnt2.scrollTop2 = PreviousScrollTop2;
    PreviousScrollTop2++;

    ReachedMaxScroll2 =
      DivElmnt2.scrollTop2 >= DivElmnt2.scrollHeight2 - DivElmnt2.offsetHeight2;
  } else {
    ReachedMaxScroll2 = DivElmnt2.scrollTop2 == 0 ? false : true;

    DivElmnt2.scrollTop2 = PreviousScrollTop2;
    PreviousScrollTop2--;
  }
}

function pauseDiv2() {
  clearInterval(ScrollInterval2);
}

function resumeDiv2() {
  PreviousScrollTop2 = DivElmnt2.scrollTop2;
  ScrollInterval2 = setInterval("scrollDiv2()", ScrollRate2);
}

由于变量名和dulpicates的原因，有很多错误。但是在resume中，你不能在body标签上有两个onLoad属性，你也不能将scrollTop设置为var，它是相应元素的属性。

ScrollRate = 100;

function init() {
  scrollDiv_init();
  scrollDiv_init_2();
}

function scrollDiv_init() {
  DivElmnt = document.getElementById("MyDivName");
  ReachedMaxScroll = false;

  DivElmnt.scrollTop = 0;
  PreviousScrollTop = 0;

  ScrollInterval = setInterval("scrollDiv()", ScrollRate);
}

function scrollDiv() {
  if (!ReachedMaxScroll) {
    DivElmnt.scrollTop = PreviousScrollTop;
    PreviousScrollTop++;

    ReachedMaxScroll =
      DivElmnt.scrollTop >= DivElmnt.scrollHeight - DivElmnt.offsetHeight;
  } else {
    ReachedMaxScroll = DivElmnt.scrollTop == 0 ? false : true;

    DivElmnt.scrollTop = PreviousScrollTop;
    PreviousScrollTop--;
  }
}

function pauseDiv() {
  clearInterval(ScrollInterval);
}

function resumeDiv() {
  PreviousScrollTop = DivElmnt.scrollTop;
  ScrollInterval = setInterval("scrollDiv()", ScrollRate);
}

ScrollRate2 = 100;

function scrollDiv_init_2() {
  DivElmnt2 = document.getElementById("MyDivName2");
  ReachedMaxScroll2 = false;

  DivElmnt2.scrollTop = DivElmnt2.scrollHeight - DivElmnt2.offsetHeight;
  PreviousScrollTop2 = DivElmnt2.scrollHeight - DivElmnt2.offsetHeight;

  ScrollInterval2 = setInterval("scrollDiv2()", ScrollRate2);
}

function scrollDiv2() {
  if (!ReachedMaxScroll2) {
    DivElmnt2.scrollTop = PreviousScrollTop2;
    PreviousScrollTop2--;

    ReachedMaxScroll2 = DivElmnt2.scrollTop == 0;
  } else {
    ReachedMaxScroll2 = DivElmnt2.scrollTop >= DivElmnt2.scrollHeight - DivElmnt2.offsetHeight ? false : true;

    DivElmnt2.scrollTop = PreviousScrollTop2;
    PreviousScrollTop2++;
  }
}

function pauseDiv2() {
  clearInterval(ScrollInterval2);
}

function resumeDiv2() {
  PreviousScrollTop2 = DivElmnt2.scrollTop;
  ScrollInterval2 = setInterval("scrollDiv2()", ScrollRate2);
