Question

我在React 16.3.2中使用了材料-ui的v1.1.0。我正在尝试创建类似于Showcase - Local Insights

的着陆页

对话框具有不透明度（查找止赎）。我正在尝试使用PaperProps for Dialog组件Dialog doc

这是我为尝试这样做而创建的组件。

import React from 'react';
import PropTypes from 'prop-types';
import { withStyles } from '@material-ui/core/styles';

import Button from '@material-ui/core/Button';

import Dialog from '@material-ui/core/Dialog';
import DialogActions from '@material-ui/core/DialogActions';
import DialogContent from '@material-ui/core/DialogContent';
import DialogTitle from '@material-ui/core/DialogTitle';

import ForwardIcon from '@material-ui/icons/Forward';

import Input from '@material-ui/core/Input';
import FormControl from '@material-ui/core/FormControl';
import Slide from '@material-ui/core/Slide';


const styles = theme => ({
  dialogPaper: {
    opacity: 0.5,
    border: '#FF0000 1px solid',
  },
  button: {
    margin: '30px'
  }
});

function Transition(props) {
  return <Slide direction="up" {...props} />;
}

class SignInDialog extends React.Component {
  state = {
    open: false,
    username: ''
  };

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

  handleClose = () => {
    this.setState({ open: false });
  };

  handleChange = name => event => {
    this.setState({
      [name]: event.target.value,
    });
  };

  render() {
    const { classes } = this.props;

    return (
      <div>
        <Button variant="fab" color="primary" aria-label="add" className={classes.button} onClick={this.handleClickOpen}>
          <ForwardIcon />
        </Button>
        <Dialog
          PaperProps={styles.dialogPaper}
          open={this.state.open}
          TransitionComponent={Transition}
          onClose={this.handleClose}
          aria-labelledby="form-dialog-title"
        >
          <DialogTitle id="form-dialog-title">WELCOME</DialogTitle>
          <DialogContent>
            <p>SIGN IN</p>
            <FormControl className={classes.formControl}>
              <Input
                value={this.state.searchString}
                onChange={this.handleChange('search')}
                id="siginin-input"
                placeholder="Enter your username"
              />
            </FormControl>
          </DialogContent>
          <DialogActions>
            <Button onClick={this.handleClose} color="primary">
              Cancel
            </Button>
            <Button onClick={this.handleClose} color="primary">
              Continue
            </Button>
          </DialogActions>
        </Dialog>
      </div>
    );
  }
}

SignInDialog.propTypes = {
  classes: PropTypes.object.isRequired,
};

export default withStyles(styles)(SignInDialog);

我无法弄清楚如何让Dialog采用这些风格。让PaperProps工作需要什么？

Answer 1

如果您想使用PaperProps，则必须指定要应用样式的Paper的道具。

<Dialog
          PaperProps={{ classes: {root: classes.dialogPaper } }}
          />

CodeSandBox Demo

您还可以使用classes属性并覆盖样式

<Dialog
          classes={{paper:classes.dialogPaper}}
          />

Answer 2

覆盖纸道具的正确方法是使用classNames

<Dialog
PaperProps={{ className: classNames(classes.dialogPaper) }}/>
