我要评论微信浏览器禁止页面下拉查看网址实例详解
此类事件是手机touchmove默认事件行为，可以通过js代码隐藏事件：
$(‘body').on(‘touchmove', function (event) {event.preventdefault();});
or
document.addeventlistener('touchmove', function(e){e.preventdefault()}, false);
但这样往往会把页面原生的scroll效果也一同去掉了，下面的代码可以完美解决这个问题：
var overscroll = function(el) {
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();
}
});
