javascript - 如何使用语义UI打开多个 Accordion 作出 react ？

我正在尝试使用包含多个条目的语义UI手风琴，并允许一次打开多个条目。每个条目都有一个标题部分，该标题部分包含一个带有弹出菜单的图标，以及一个包含文本区域的内容区域。

我希望能够同时打开两个手风琴，当按documentation here中所述制作手风琴元素时，显然通过使用exclusive={false}道具得到支持。

但是该示例似乎使用的对象数组的内容是字符串，而不是其他react / html / jsx元素（在我的情况下是语义ui图标，弹出窗口和文本区域）。该对象数组被传递到手风琴的panel道具。

而且，我不了解语义ui反应手风琴在跟踪索引和其他内容时正确运行所需的功能，我不确定我还需要配置什么，或者不确定是否可以使用语义ui组件。

我基本上复制了this example并使用了活动索引和onclick处理程序，该处理程序在组件反应状态下切换了活动索引。

这是手风琴和onclick处理程序的片段，并对应用程序状态做出反应：

class FileUpload extends Component {

 // other stuff omitted

  constructor(props) {
    super(props);

    this.state = {
      activeAccordionIndex: -1
    };

  handleAccordionClick = (e, titleProps) => {
     const { index } = titleProps;
     const { activeAccordionIndex } = this.state;
     const newIndex = activeAccordionIndex === index ? -1 : index;

     this.setState({
       activeAccordionIndex: newIndex
     })
   }

 // I'm using a small helper function to create the accordion and invoke it in
 // the render method, just one item for brevity; the other entries are pretty
 // much the same

getAccordionInputs() {

     const { activeAccordionIndex } = this.state;

     let accordionContent = (
      <Accordion fluid exclusive={false}>
         <Accordion.Title
           className="file-upload-ordinal-accord-title"
           active={activeAccordionIndex === 0}
           index={0}
           onClick={this.handleAccordionClick}
          >
           <Icon name='dropdown' />
           Enter Ordinal Features
           <Popup
             on="click"
             position="right center"
             header="Ordinal Features Help"
             content={
               <div className="content">
                 <p>Ordinal Features help description</p>
               </div>
             }
             trigger={
               <Icon
                 className="file-upload-ordinal-help-icon"
                 inverted
                 size="large"
                 color="orange"
                 name="info circle"
               />
             }
           />
         </Accordion.Title>
         <Accordion.Content
            active={activeAccordionIndex === 0}
          >
           <textarea
             className="file-upload-ordinal-text-area"
             id="ordinal_features_text_area_input"
             label="Ordinal Features"
             placeholder={"{\"ord_feat_1\": [\"MALE\", \"FEMALE\"], \"ord_feat_2\": [\"FIRST\", \"SECOND\", \"THIRD\"]}"}
             onChange={this.handleOrdinalFeatures}
           />
         </Accordion.Content>
       </Accordion>
     )
     return accordionContent;
   }

  }

我不知道如何设置此功能以允许同时打开多个不是字符串的内容的手风琴。语义ui手风琴有可能吗？还是我需要找到替代解决方案和/或手工制作具有所需行为的零件？

最佳答案

您可以更改索引逻辑，因此无需在状态中设置活动索引，而是将索引添加到数组中并检查它是否存在于数组中以及是否确实显示了手风琴

这是一个例子：

export default class AccordionExampleStandard extends Component {
  state = { activeIndexs: [] };

  handleClick = (e, titleProps) => {
    const { index } = titleProps;
    const { activeIndexs } = this.state;
    const newIndex = activeIndexs;

    const currentIndexPosition = activeIndexs.indexOf(index);
    if (currentIndexPosition > -1) {
      newIndex.splice(currentIndexPosition, 1);
    } else {
      newIndex.push(index);
    }

    this.setState({ activeIndexs: newIndex });
  };

  render() {
    const { activeIndexs } = this.state;

    return (
      <Accordion>
        <Accordion.Title
          active={activeIndexs.includes(0)}
          index={0}
          onClick={this.handleClick}
        >
          <Icon name="dropdown" />
          What is a dog?
        </Accordion.Title>
        <Accordion.Content active={activeIndexs.includes(0)}>
          <p>
            A dog is a type of domesticated animal. Known for its loyalty and
            faithfulness, it can be found as a welcome guest in many households
            across the world.
          </p>
        </Accordion.Content>

        <Accordion.Title
          active={activeIndexs.includes(1)}
          index={1}
          onClick={this.handleClick}
        >
          <Icon name="dropdown" />
          What kinds of dogs are there?
        </Accordion.Title>
        <Accordion.Content active={activeIndexs.includes(1)}>
          <p>
            There are many breeds of dogs. Each breed varies in size and
            temperament. Owners often select a breed of dog that they find to be
            compatible with their own lifestyle and desires from a companion.
          </p>
        </Accordion.Content>

        <Accordion.Title
          active={activeIndexs.includes(2)}
          index={2}
          onClick={this.handleClick}
        >
          <Icon name="dropdown" />
          How do you acquire a dog?
        </Accordion.Title>
        <Accordion.Content active={activeIndexs.includes(2)}>
          <p>
            Three common ways for a prospective owner to acquire a dog is from
            pet shops, private owners, or shelters.
          </p>
          <p>
            A pet shop may be the most convenient way to buy a dog. Buying a dog
            from a private owner allows you to assess the pedigree and
            upbringing of your dog before choosing to take it home. Lastly,
            finding your dog from a shelter, helps give a good home to a dog who
            may not find one so readily.
