微信瀏覽器禁止頁面下拉查看網址實例詳解

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