我使用此代码, 在ipad中滚动溢出div(隐藏),并且工作期望它不流畅,有什么方法可以让它平滑滚动吗?
function initMobileScroll(ele) {
var mobileScrollArea = document.getElementById(ele);
mobileScrollArea.addEventListener('touchstart', function(event){
touchstart (event);
});
mobileScrollArea.addEventListener('touchmove', function(event){
touchmove (event);
});
// let’s set the starting point when someone first touches
function touchstart (e) {
startY = e.touches[0].pageY;
startX = e.touches[0].pageX;
}
// calls repeatedly while the user’s finger is moving
function touchmove(e) {
var touches = e.touches[0];
// override the touch event’s normal functionality
e.preventDefault();
// y-axis
var touchMovedY = startY - touches.pageY;
startY = touches.pageY; // reset startY for the next call
mobileScrollArea.scrollTop = mobileScrollArea.scrollTop + touchMovedY;
// x-axis
var touchMovedX = startX - touches.pageX;
startX = touches.pageX; // reset startX for the next call
mobileScrollArea.scrollLeft = mobileScrollArea.scrollLeft + touchMovedX;
}
}

Smooth Div scroll现在支持触摸滚动。它是免费的,就像你描述的那样 - 在另一个div中滚动一个div,隐藏溢出。

看起来和我试图做的相似......祝你好运
if (evt.type == "touchstart")
{
tsStartY = evt.originalEvent.changedTouches[0].clientY;
}
if (evt.type == "touchend")
{
var te = evt.originalEvent.changedTouches[0].clientY;
var delta = tsStartY - te;
if (tsStartY > te) {
// going down
this.transY += delta;
if (this.transY > this.minY)
{
this.transY = this.minY;
}
}
if (tsStartY < te)
{
// going up
this.transY -= -delta;
if (this.transY < this.maxY) {
this.transY = this.maxY;
}
}
}
