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();
   }
});
