编写的 Material UI 组件是基于功能的组件吗？

Question

我正在尝试将材料 ui 组件用于基于反应类的组件材料 ui 组件演示一切基于函数，但我们编写的所有项目页面都是基于类的，很难集成材料 UI 组件

Answer 1

在基于类的组件上集成并不难。是的，在 Material UI 文档中，所有东西都使用 Hooks 集成在基于功能的组件上。但是你应该有一些关于钩子和状态概念的知识，然后你就可以很容易地集成它们。 例如：

  export default function AlertDialog() {
  const [open, setOpen] = React.useState(false);

  const handleClickOpen = () => {
    setOpen(true);
  };

  const handleClose = () => {
    setOpen(false);
  };

  return (
    <div>
      <Button variant="outlined" color="primary" onClick={handleClickOpen}>
        Open alert dialog
      </Button>
      <Dialog
        open={open}
        onClose={handleClose}
        aria-labelledby="alert-dialog-title"
        aria-describedby="alert-dialog-description"
      >
        <DialogTitle id="alert-dialog-title">{"Use Google's location service?"}</DialogTitle>
        <DialogContent>
          <DialogContentText id="alert-dialog-description">
            Let Google help apps determine location. This means sending anonymous location 
         data to
            Google, even when no apps are running.
          </DialogContentText>
        </DialogContent>
        <DialogActions>
          <Button onClick={handleClose} color="primary">
            Disagree
          </Button>
          <Button onClick={handleClose} color="primary" autoFocus>
            Agree
          </Button>
        </DialogActions>
      </Dialog>
    </div>
  );
}

所以，这个对话框代码是用基于函数的组件编写的，但是我们可以很容易地集成在基于类的组件上，比如：

 export default  class  AlertDialog extends React.Components{
  constructor(){

 super(props)
this.state={
    open:false
    }
  }


  handleClickOpen = () => {
    this.setState({open:true})
  };

  handleClose = () => {
       this.setState({open:false})
  };
render(){
  return (
    <div>
      <Button variant="outlined" color="primary" onClick={handleClickOpen}>
        Open alert dialog
      </Button>
      <Dialog
        open={this.state.open}
        onClose={this.handleClose}
        aria-labelledby="alert-dialog-title"
        aria-describedby="alert-dialog-description"
      >
        <DialogTitle id="alert-dialog-title">{"Use Google's location service?"}</DialogTitle>
        <DialogContent>
          <DialogContentText id="alert-dialog-description">
            Let Google help apps determine location. This means sending anonymous location 
         data to
            Google, even when no apps are running.
          </DialogContentText>
        </DialogContent>
        <DialogActions>
          <Button onClick={this.handleClose} color="primary">
            Disagree
          </Button>
          <Button onClick={this.handleClose} color="primary" autoFocus>
            Agree
          </Button>
        </DialogActions>
      </Dialog>
    </div>
  );
}
}

所以，只要我们了解基本的 React 概念，你就可以做到这一点。
