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(如果页面没有内嵌scroll,可以直接用此解决方案),下面的代码可以不是十分完美的解决这个问题:
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(); } });
要给需要下拉的box添加一个class="scroll"就可以了
此方法对安卓的下拉不起效 但是不影响使用 主要为了解决苹果端页面上下拉之后导致页面内部scroll划不动的现象
