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

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

uniapp 微信小程序和H5的弹窗滚动穿透解决

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:

uniapp 微信小程序和H5的弹窗滚动穿透解决

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

uniapp 微信小程序和H5的弹窗滚动穿透解决

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。

uniapp 微信小程序和H5的弹窗滚动穿透解决

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;

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
