HomeWeb Front-endHTML Tutorial手机页面滚动穿透问题【原创】_html/css_WEB-ITnose

最近在写的微信页面有遇到一个问题:就是点击页面一个按钮出来弹框和透明蒙版后,理论上底部的父页面是不可以被操作的。但是现在对当前弹框和透明蒙版组成的页面滑动时,底部的父页面还是会跟着滚动,这也就是所谓的手机页面穿透问题。

百度了很多方法后,还是没能完美的解决这个问题。不过这里也将把这些方法总结列举一下,期待后面有更好的解决办法。

方法一:

.alpha {     height: 100%;     overflow: hidden;     position: relative;}.alpha body {     height: 100%;     overflow: hidden;}

当你切换弹框出现或隐藏的时候只要切换该css,即:

$('html').toggleClass('alpha');

当然在实际使用的时候你可能需要拆开使用这句代码,如当你点击按钮让弹框出来的时候需要使用该css,即用:

$('html').toggleClass('alpha');

当你点击确定或取消让弹框消失的时候,你需要去掉该css使父页面恢复正常滚动状态,即:

$('html').removeClass('alpha');

该方法的缺点就是当你的页面内容一屏显示不完时,需要滚动屏幕显示全部内容时,你的弹框会出现在页面内容的顶部,因为上面的css已经将页面高度定义成了屏幕高度,所以页面下面的部分也就相当于暂时截取掉了,当你隐藏弹框的时候,你也是在页面顶部,不会默认回到你之前点击按钮(按钮在页面底部)的地方,在页面很长的时候用户体验不是很好。方法二:

.noscroll {    position: fixed!important}
var page = document.getElementsByTagName('body')[0];//禁止页面滚动page.classList.add('noscroll');//恢复页面滚动page.classList.remove('noscroll');

也有上面的缺点方法三:

//If you want to use the iframe's scrollbar and not the parent's use thisdocument.body.style.overflow = 'hidden';//If you want to use the parent's scrollbar and not the iframe's then you need to use:document.getElementById('your_iframes_id').scrolling = 'no';or set the scrolling="no" attribute in your iframe's tag: <iframe src="some_url" scrolling="no">

该方法不会出现上面的问题,但是可惜的是在手机页面没用,只在pc浏览器有用。
