Question

有没有人有任何想法会导致滚动不能在safari上工作但是在chrome上工作？这两个都在OSX上。

在我的控制台中，我记录了delta，出于某种原因，对于弱滚动，它总是记录3或-3。如果我连续滚动了很多次，那么它最终会向下或向上滚动。这是视差滚动。这是我的代码：

function parallaxScroll(evt) {
  console.log("what about this")
  if (isFirefox) {
    //Set delta for Firefox
    delta = evt.detail * (-120);
  } else if (isIe) {
    //Set delta for IE
    delta = -evt.deltaY;
  } else {
    //Set delta for all other browsers
    delta = evt.wheelDelta;
    console.log(delta)
  }

  if (ticking != true){
    if (delta <= -scrollSensitivitySetting) {
      //Down scroll
      ticking = true;
      if (currentSlideNumber !== (totalSlideNumber - 1)) {
        currentSlideNumber++;
        nextItem();
      }
      slideDurationTimeout(slideDurationSetting);
    }
    if (delta >= scrollSensitivitySetting) {
      //Up scroll
      ticking = true;
      if (currentSlideNumber !== 0) {
        currentSlideNumber--;
        previousItem();
      }
      slideDurationTimeout(slideDurationSetting);
    }
  }
}

所以问题似乎没有变换：translate3d和我的webkit转换以及溢出设置为auto。设置溢出到隐藏并添加转换：translate3d到处都使用webkit-transform修复了我的问题。

Javascript滚动不工作safari但适用于chrome OSX
