【未解决】ReactJS中如何给可以滚动的页面右边加上垂直方向的滚动条

ReactJS crifan 213浏览 0评论

对于可滚动的页面来说,在滚动的时候,希望右边显示出滚动条。

对于Chrome的调试来说,是可以看到滚动条的:

但是发布到手机端后,iOS和安卓都看不到滚动条。

所以需要去调试看看。

但是之前记得是:

overflow:scroll 或auto

就可以看到滚动条了?

        overlfow: ‘scroll’ // <– This tells the modal to scrol

此处,之前滚动的element是:

对应着之前已经设置了:

#app {
  width: 100%;
  height: 100%;
  // height: calc(~"100% – 49px");
  overflow: auto;
}

结果却不显示滚动条

去试试:

#app {
  width: 100%;
  height: 100%;
  // height: calc(~"100% – 49px");
  // overflow: auto;
  overflow-y: scroll;
  -webkit-overflow-scrolling: touch;
}
.container {
  max-width: 750px;
  min-width: 320px;
  // min-height: 100%;
  clear: both;
  //margin: 0.88rem auto 30px;
  // margin: 0.88rem auto 100px;
  margin: 0.88rem auto 49px;
  background: #fff;
  min-height: 10rem;
  overflow-y: scroll;
  -webkit-overflow-scrolling: touch;
}

但是:

(2个)android手机没有生效

1个iPhone6生效了,但是带了个问题:

此处是针对整个app的整个屏幕的高度去滚动条的。而且滚动期间还导致底部的tab不显示了。。。

css – Overflow:hidden not working on mobile browser – Stack Overflow

去试试

    <meta name="viewport" content="width=device-width, initial-scale=1.0, minimal-ui">

改为:

    <meta name="viewport" content="width=device-width, height=device-height, initial-scale=1.0, minimal-ui">

其中,有点点怀疑,和minimal-ui是否有关系。

但是早晚要去解决的:

【已解决】ReactJS项目在iOS的Safari模拟器中报错:Viewport argument key "minimal-ui" not recognized and ignored

抽空再试试:

user-scalable=no,maximum-scale=1

算了,不去试了,前面的:

height=device-height

没有效果。

估计user-scalable=no,maximum-scale=1也是没效果的。

去试试:

souhe/reactScrollbar: Scrollbar component for React

结果直接就出错:

ERROR in ./~/react-scrollbar/dist/scrollArea.js

         + 4 hidden modules
webpack: Failed to compile.

再去试试:

BosNaufal/react-scrollbar: The Simplest Scroll Area Component with custom scrollbar for React JS 

import ReactScrollbar from ‘react-scrollbar-js’;
    <ReactScrollbar>
      <div class={style.the_herd_all}>
        <Search
          placeholder="请输入牛号搜索"
          onInputChange={this.onInputChange}
        />
          <div class={style.nn_a_list}>
            <Scroll
              loadMore={this.loadMore}
              hasMore={this.state.hasMore}
              showLoading={this.state.isLoading}
            >
            {
              this.state.cowList.map(item => {
                return (
                  <CowListItem
                    data={item}
                    reproductiveStateTypeDict={this.state.reproductiveStateTypeDict}
                  />
                );
              })
            }
            </Scroll>
          </div>
      </div>
    </ReactScrollbar>

然后在模拟器上有效果:

看看真机上如何。

结果iOS上无法滑动+无法点击。

android上,初始时看到滚动条,但是要拖动才能下拉不方便滑动,也是无法点击了。

算了。放弃。
