以下解决方案由 HMR 在评论中发起。
问题是所有模态都显示出来,只有最后一个可见。通过将模态移出状态并从状态中.map更新 ID.map并将状态 ID 传递给模态内的新嵌套组件来修复。
还切换到使用动态 CSS 来显示和隐藏基于状态的模式。
仪表板.jsx
export default class Snippets extends Component {
constructor(props) {
super(props)
this.showModal = React.createRef()
this.state = {
snippets: [],

handleDelete = id => event => {
event.preventDefault()
api
.deleteSnippet(id)
.then(result => {
console.log('DATA DELETED')
api.getSnippets().then(result => {
this.setState({ snippets: result })
console.log('CLIENT UPDATED')
})
})
.catch(err => this.setState({ message: err.toString() }))

handleModal = id => {
this.setState({ sid: id })
this.showModal.current.showModal()

我不确定 handleDelete 函数。但更换线路应该可以解决问题
<button onClick={() => this.handleDelete(snippet._id)}>

一个潜在的问题是this.handleDelete(snippet._id)
will 立即触发而不是onClick
,因此您需要在事件侦听器中添加一个匿名函数:
() => this.handleDelete(snippet._id)
代替
this.handleDelete(snippet._id)
