Question

我搜索了一些问题，我发现的唯一消失的相关问题是当人们在模态上使用它时，他们谈到设置z-index来修复它。无论如何我还是没试过。我该如何解决这个问题？

import React from 'react';
import PlaylistPages from './PlaylistPages';

class PlaylistSortableComponent extends React.Component {
  constructor(props, context) {
    super(props, context);

    this.state = {
      test: [
        '1','2', '3', '4'
      ]
    }
  }

  render() {
    return (
      <PlaylistPages pages={this.state.test} style={{zIndex: 999999}} />
    );
  }
}   


const PlaylistPages = SortableContainer(({pages}) => {
  return (
    <div>
      {
        pages.map((page, index) =>
          <PlaylistPage key={index} page={page} style={{zIndex: 99999999}} />
      )}
    </div>
  );
});   

const PlaylistPage = SortableElement(({page}) => {
  return (
    <div style={{zIndex: 99999999}} >{page}</div>
  );
});

Answer 1

每个sortableElement应该拥有它自己的index道具：

<PlaylistPage key={index} index={index} page={page} style={{zIndex: 99999999}} />

我遇到了同样的问题， Dekel 是正确的。就我而言，z-index可修复错误：

<SortableList
    axis="y"
    helperClass="sortable-list-tab"
    lockAxis="y"
    distance={0}
    onSortEnd={onSortEnd}
>
    <ul>
       {toolItems.map((value, index) => (
          <SortableItem key={`item-${index}`} index={index}>
              <li className="sortable-list-tab" >
                 <Button type="dashed">{`${value.label} (${index + 1})`}</Button>
              </li>
          </SortableItem>
        ))}
    </ul>
</SortableList>

sortable-list-tab类如下：

.sortable-list-tab {
    cursor: default;
    visibility: visible;
    z-index: 99999999;
    list-style-type: none;
    padding: .3em;
  }

react-sortable-hoc列表在拖动元素时消失
