网页加载完调用
$(function(){
var overscroll = function (els) {
for (var i = 0; i < els.length; ++i) {
var el = els[i];
el.addEventListener(‘touchstart‘, function () {
var top = this.scrollTop
, totalScroll = this.scrollHeight
, currentScroll = top + this.offsetHeight;
//If we‘re at the top or the bottom of the containers
//scroll, push up or down one pixel.
//
//this prevents the scroll from "passing through" to
//the body.
if (top === 0) {
this.scrollTop = 1;
} else if (currentScroll === totalScroll) {
this.scrollTop = top - 1;
}
});
el.addEventListener(‘touchmove‘, function (evt) {
//if the content is actually scrollable, i.e. the content is long enough
//that scrolling can occur
if (this.offsetHeight < this.scrollHeight)
evt._isScroller = true;
});
}
};
//禁止body的滚动事件
document.body.addEventListener(‘touchmove‘, function (evt) {
//In this case, the default behavior is scrolling the body, which
//would result in an overflow. Since we don‘t want that, we preventDefault.
if (!evt._isScroller) {
evt.preventDefault();
}
});
//给class为.scroll的元素加上自定义的滚动事件
overscroll(document.querySelectorAll(‘.scroll‘));
})
如果页面中有需要滚动的元素，在div加上scroll类
html{
width: 100%;
height: 100%;
overflow: hidden;
}
body{
width: 100%;
height: 100%;
overflow: hidden;
}
最外层外包div.scroll元素 让次元素可滚动
