I'm trying to replicate the example of a modal from material ui examples but I can't make it work, first I was getting a "Cannot read property 'setState' of undefined" I solved that and now there are no errors in the console but when I click on the button that displays the modal nothing happens.
Im using material-ui v1.0.0-beta.31
This is the code:
import React from 'react';
import PropTypes from 'prop-types';
import { withStyles } from 'material-ui/styles';
import Typography from 'material-ui/Typography';
import Modal from 'material-ui/Modal';
import Button from 'material-ui/Button';
function rand() {
return Math.round(Math.random() * 20) - 10;
}
function getModalStyle() {
const top = 50 + rand();
const left = 50 + rand();
return {
top: `${top}%`,
left: `${left}%`,
transform: `translate(-${top}%, -${left}%)`,
};
}
const styles = theme => ({
paper: {
position: 'absolute',
width: theme.spacing.unit * 50,
backgroundColor: theme.palette.background.paper,
boxShadow: theme.shadows[5],
padding: theme.spacing.unit * 4,
},
});
class SimpleModal extends React.Component {
constructor(props) {
super(props);
this.state = {
open: false
};
this.handleOpen = this.handleOpen.bind(this);
this.handleClose = this.handleClose.bind(this);
}
handleOpen() {
this.setState({ open: true });
};
handleClose(){
this.setState({ open: false });
};
render() {
const { classes } = this.props;
return (
<div>
<Typography gutterBottom>Click to get the full Modal experience!</Typography>
<Button onClick={this.handleOpen}>Open Modal</Button>
<Modal
aria-labelledby="simple-modal-title"
aria-describedby="simple-modal-description"
open={this.state.open}
onClose={this.handleClose}
>
<div style={getModalStyle()} className={classes.paper}>
<Typography type="title" id="modal-title">
Text in a modal
</Typography>
<Typography type="subheading" id="simple-modal-description">
Duis mollis, est non commodo luctus, nisi erat porttitor ligula.
</Typography>
<SimpleModalWrapped />
</div>
</Modal>
</div>
);
}
}
SimpleModal.propTypes = {
classes: PropTypes.object.isRequired,
};
const SimpleModalWrapped = withStyles(styles)(SimpleModal);
export default SimpleModalWrapped;
From the original example the only difference with the code above is that I add the following:
constructor(props) {
super(props);
this.state = {
open: false
};
this.handleOpen = this.handleOpen.bind(this);
this.handleClose = this.handleClose.bind(this);
}
Thanks!
Try binding this
when rendering the button:
<Button onClick={this.handleOpen.bind(this)}>Open Modal</Button>
And likewise, for modal,
onClose={this.handleClose.bind(this)}
, no need for these lines:
this.handleOpen = this.handleOpen.bind(this);
this.handleClose = this.handleClose.bind(this);
