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，其中包含一个附有弹出窗口的图标和一个包含textarea的内容区域。
我希望能够同时打开两个手风琴，显然支持使用exclusive={false}道具制作手风琴元素，如documentation here所述
但是这个例子看起来是使用一个对象数组，其内容是一个字符串，而不是其他的react / html / jsx元素（在我的例子中，它是语义ui图标，弹出窗口和textareas）。那个对象数组传递给手风琴的panel道具。
而且我不熟悉手风琴所需要的语义ui能够正确运行以及跟踪索引和其他内容，我不知道还需要配置什么，或者这是否可以使用语义ui组件。
我基本上复制了this example并使用一个活动索引和一个onclick处理程序来切换组件反应状态中的活动索引。
这是手风琴和onclick处理程序的片段并反应应用程序状态：
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;
}
}
我不知道如何设置它以允许多个手风琴一次打开，内容不是字符串。用语义ui手风琴可以实现吗？或者我是否需要找到替代解决方案和/或手动制作具有所需行为的部件？
您可以更改索引逻辑，而不是在您的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" />

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.
