微信浏览器禁止页面下拉查看网址实例详解

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(documenthttp://.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();http://

}

});
