关闭按钮不适用于 react-bootstrap 模态组件

Question

我正在尝试使用 react-bootstrap 模式和反应状态显示另一个组件。我正在遵循 react-bootstrap 模式代码并尝试以我自己的方式自定义状态。我能够在不使用 React.useStae 的情况下创建打开模式的状态。但问题是当我单击关闭按钮时模式没有关闭。那么，我该如何解决这个状态问题呢？

这是我正在关注的 react-bootstrap 模式代码：

这是我试图在模态中打开另一个组件的代码。但关闭 btn 不起作用：

export default Shirts;

Answer 1

您的模态引用 this.state.show，但您的 handleCLose/Show 函数正在设置 this.state.setShow。

您应该设置“显示”

  handleClose = () => {this.setState({show:false})};
  handleShow = () =>{this.setState({show:true})};

您正在查看的示例是一个功能组件，其中 setShow 是 useState 挂钩的突变方法。您正在使用一个基于类的组件，该组件使用 setState 来改变其状态。
