I am using react and everytime after navigating away from a page, the state goes back to original state. I have a state that is set when a user clicks on a button. This handles the setState of listView
which is a boolean. So if listView is true, then the view would be listView and vice versa. The issue is that if I choose the other view, and refresh the page, immediately after it would go back to listView. Now I saw how to persist state using hooks by doing some research but I couldnt find an example of doing this in a class component that really is similar to my example. Please see my code. Thanks!
constructor(props) {
super(props);
this.state = {
listView: true,
};
}
And the toggle area that setStates of the listView to be true or false, not really necessary, but just in case:
<ToggleButtonGroup className={classes.toggleButtonContainer} exclusive orientation="horizontal">
<ToggleButton className={listView ? classes.selectedToggleButton : '' } selected={listView} onClick={() => this.setState({ listView: true })} value="list" aria-label="list">
<Icon fontSize="large" color="default">view_list</Icon>
</ToggleButton>
<ToggleButton className={!listView ? classes.selectedToggleButton : '' } selected={!listView} onClick={() => this.setState({ listView: false })} value="module" aria-label="module">
<Icon fontSize="large" color="default">view_module</Icon>
</ToggleButton>
</ToggleButtonGroup>
You can achieve this with different methods:
React-Redux , alternative Context API
Adding and Fetching state value from localStorage
like this:
constructor(props) { super(props); this.state = { listView: JSON.parse(localStorage.getItem('listView')) || [] } } renderListView = (selection) => {... this.setState({ listView: selection },() => { localStorage.setItem('listView', JSON.stringify(this.state.listView)) }); }
Pushing into URL as query param after every response change:
history.push({pathname: 'path/', search: '?' + Qs.stringify(params)}); //fetch the params from URL params = Qs.parse(nextProps.location.search.substring(1)); //add it to your local state of particular component this.setState({selectedOption: params.selectedOption});
