滚动穿透:
页面里的弹窗也是可以滚动的,然后页面本身内容多所以也是滚动的,就造成,在弹窗滚动的时候,页面内容也跟着滚动了。如图所示
ps: 电脑端分鼠标滚轮滚动和长按鼠标拖拽滚动,手机端只有触屏滑屏滚动,即像电脑端的长按鼠标拖拽滚动
我是在电脑上录屏的,所以两种情况的滚动穿透我都录上去
鼠标滚轮滚动的穿透
长按鼠标拖拽滚动的穿透
解决滚动穿透:
前提: 我用了UViewUi1.0版本的弹窗组件
Popup 弹出层 | uView - 多平台快速开发的UI框架 - uni-app UI框架
然后我的场景是内容局部滚动,UView提供的内容局部滚动方案如下:
所以结构是这样的
<u-popup mode="bottom" v-model="show">
<view class="content">
<scroll-view scroll-y="true" style="height: 500rpx;">
<view>
局部内容局部内容
</view>
</scroll-view>
<view class="confrim-btn">
<u-button @click="show = false;">确定</u-button>
</view>
</view>
</u-popup>
1 解决电脑端长按鼠标拖拽滚动,即手机端的触屏滑屏滚动穿透问题(主要)
电脑端
重要代码:
@touchmove.stop.prevent="() => {}"
这句代码加在scroll-view上
手机端
重要代码(我找了好久才找到这个属性的):
overscroll-behavior-y: contain !important;
简单了解看这个:
https://www.jianshu.com/p/fb95e6552d13
完整学习看这个:
overscroll-behavior - CSS(层叠样式表) | MDN
这句代码是css的,因为用了UView的组件,所以这个要阻断滚轮链,就得要阻断真的滚动区域(最顶上的父级),直接加在我们的局部滚动scroll-view上是无效的,要加在最顶上的父级滚动区,这个需要你开调试者工具找,因为你可能用别的组件,多包了几层。
想改变深层元素的深层样式,代码如下
ps:
1、因为是改变了深层元素的样式,所以要手动刷新一下,不要热刷新,会没效果哈。
2、uniapp的插件引入,支持自己直接改源码的,所以,你可以直接去UView的弹窗文件里修改,就不用加 /deep/了。
2 解决电脑端的鼠标滚轮滚动穿透
其实是因为弹窗和弹窗的遮罩层(阴影层)没有阻止电脑端的鼠标滚轮滚动的操作,所以就导致了还存在鼠标滚轮滚动穿透。
这是是用了UView的组件的问题,所以直接去源码里改
重要代码
@mousewheel.prevent
遮罩层 u-mask:
弹窗 u-popup :
直接在这加,那弹窗的所有地方都不能鼠标滚动了,包括你自己的scrollview区域。
u-popup 的禁止滚轮滚动这个可以不弄,因为滚轮滚动挺方便的,想保留自己的scrollview区域的鼠标滚动,就要在非scrollview的地方加阻断滚轮事件的操作。而且只要加了下面的代码的,在你的局部滚动处(scrollview)滚轮滚动的穿透基本无了。
overscroll-behavior-y: contain !important;
我的完整效果代码(uview源码修改的就不贴了)
弹窗
<!-- @touchmove.stop.prevent 在u-popup已经设置了,所以触摸的滚动是阻断的,电脑鼠标滚轮滚动没阻断而已 -->

<u-icon name="close" color="#999999" size="28" @tap="onPopupClose"></u-icon>
</view>
<!-- @touchmove.stop.prevent="() => {}" 写在 scroll-view 里是为了兼容电脑端,阻断上下拖拽动作 ,手机端 使用 overscroll-behavior-y: contain !important;就足够阻断滚动穿透了,@mousewheel.prevent阻止电脑端滚轮滚动穿透-->

因为从自己代码里扣出来的,所以可能漏东西,但是问题不大,漏啥你们再自己补补就好了。
ps:
最后发现,在手机端我一个手指长按屏幕的在弹窗滑倒底部的时候,手指不松开,马上把另一个手的手指按住屏幕不松开的滑上滑下,发现还是存在滚动穿透了,只有这样操作的情况下才存在,所以我的解决方法没有很完美,如果你有其他的好法子请告诉我,谢谢。
搜了一下,一只手指按住屏幕另一只手指划得动屏幕叫做多点触控。
