本人需要做一个web端的网页，需要通过微信自带浏览器打开，

但是微信自带浏览器往下拖动会动态查看网页网址，影响网页的用户体验。

翻到一篇文章来讲通过代码来禁止微信下拉查看网页。

禁止微信浏览器下拉查看网址

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();});ordocument.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();  }});
