I have a parent component in which I'm struggling to properly open/close the child component (modal). The two code boxes below are simplified examples of my components.
EDIT: Here is a code sandbox with the following code -- there isn't an actual modal, however i've logged all of the stateful values that I assume will have an effect on this problem and you can see how they change/don't change as I hope they would.
Thanks to whoever reaches out, and if you have any clarifying questions feel free to ask!
class Parent extends Component {
constructor(props) {
super(props);
this.showModal = this.showModal.bind(this);
this.closeModal = this.closeModal.bind(this)
this.state = {
showModal: false
};
this.showModal = this.showModal.bind(this)
this.closeModal = this.closeModal.bind(this)
}
showModal() {
this.setState({ showModal: true });
}
closeModal() {
this.setState({ showModal: false });
}
render() {
return (
<MenuItem onClick={this.showModal}>
<ChildComponent
prop1={prop1}
isOpen={this.state.showModal}
closeModal={this.closeModal}
/>
</MenuItem>
)}
const ChildComponent = ({
prop1,
isOpen,
closeModal
}) => {
const [modalOpen, setModalOpen] = useState(isOpen)
useEffect(() => {
setModalOpen(isOpen)
},[isOpen])
console.log('isopen on child', isOpen)
console.log('modalOpen', modalOpen)
return (
<div>
{modalOpen && (
<button
onClick={() => {
setModalOpen(false)
closeModal()
}}
>
{'click to close modal'}
</button>
)}
</div>
)}
)}
I figured out my problem!
In my parent component the onClick handler that sets the modal open wrapped my child component. I needed to remove it and conditionally render it separately like so:
<div>
<div onClick={this.showModal}>{"Click here to open modal"}</div>
{this.state.showModal && (
<ChildComponent
prop1={prop1}
isOpen={this.state.showModal}
closeModal={this.closeModal}
/>
)}
</div>
