el.addEventListener(‘touchstart‘, function() {
var top = el.scrollTop ,
totalScroll = el.scrollHeight ,
currentScroll = top + el.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) {
el.scrollTop = 1;
} else if(currentScroll === totalScroll) {
el.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(el.offsetHeight < el.scrollHeight)
evt._isScroller = true;
});
}
overscroll(document.querySelector(‘.scroll‘));
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();
}
});
此類事件是手機touchmove默認事件行為,可以通過js代碼隱藏事件:
$(‘body’).on(‘touchmove’, function (event) {event.preventDefault();}); or document.addEventListener(‘touchmove‘, function(e){e.preventDefault()}, false); 但這樣往往會把頁面原生的scroll效果也一同去掉了,下面的代碼可以完美解決這個問題: var overscroll = function(el) {詳情見:https://github.com/luster-io/prevent-overscroll/blob/master/index.html
