微信浏览器禁止页面下拉查看网址

时间:2022-01-25 18:29:48

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();});
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();
}
});
