问题:ActionSheet滚动不了。
使用uview ui :u-action-sheet, 但是item太多,超出屏幕了, 查了一下文档,并没有设置滚动的地方。
官方文档:ActionSheet 操作菜单 | uView - 多平台快速开发的UI框架 - uni-app UI框架
解决
只能修改源码了,在v-for遍历外面添加一个滚动视图,即可,其他不变
<template>
<u-popup mode="bottom" :border-radius="borderRadius" :popup="false" v-model="value" :maskCloseAble="maskCloseAble"
length="auto" :safeAreaInsetBottom="safeAreaInsetBottom" @close="popupClose" :z-index="uZIndex">
<view class="u-tips u-border-bottom" v-if="tips.text" :style="[tipsStyle]">
{{tips.text}}
</view>
<scroll-view scroll-y style="min-height: 100rpx;max-height: 700rpx;">
<block v-for="(item, index) in list" :key="index">
<view
@touchmove.stop.prevent
@tap="itemClick(index)"
:style="[itemStyle(index)]"
class="u-action-sheet-item u-line-1"
:class="[index < list.length - 1 ? 'u-border-bottom' : '']"
:hover-stay-time="150"
>
<text>{{item.text}}</text>
<text class="u-action-sheet-item__subtext u-line-1" v-if="item.subText">{{item.subText}}</text>
</view>
</block>
</scroll-view>
<view class="u-gab" v-if="cancelBtn">
</view>
<view @touchmove.stop.prevent class="u-actionsheet-cancel u-action-sheet-item" hover-class="u-hover-class"
:hover-stay-time="150" v-if="cancelBtn" @tap="close">{{cancelText}}</view>
</u-popup>
</template>
效果:控制差不多半屏显示了,不超屏幕了。 在电脑上用鼠标滚轮很正常。但是在手机滚动不了。
问题2: 手机上触摸滚动不了。
再去看源码,发现包裹着block里的view禁止触摸事件,导致滚动视图滚动不了。把@touchmove.stop.prevent删除即可
最终代码
