}微信浏览器禁止页面下拉查看网址（不影响页面内部scroll）
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();
}
});
