By : Davood Khani

With these it helps You need to pass a callback as a props in Child component, it will update Parent Component when you click on closeButton in child.
code :
// Parent Component
callbackModal = () => {
   this.setState({ showModal: false });
}
//ChildButton
closeButtonClickHandler = () => {
  this.props.callbackModal();
}

React: Closing Modal in Child Component from Parent


By : Christopher Norman

fixed the issue. Will look into that further I have a modal in a child component that handles a delete function in the parent component. The child is holding the state of the modal (open or closed) as this seems the most logical place for it. , You could use a ref to call the child close function?
Parent
code :
    removeItem() {
       console.log('clicked');
       this.child.close();
    }

   render() {
      return (
         <div>
            <ChildWithModal ref={(ref) => { this.child = ref; }} />
         </div>
      );
   }
...

close() {
   this.setState({ showModal: false })
};

React component tree close previously opened parent node

With these it helps I'm not going to edit the Codepen and do all the work for you, but I'll give you a general idea of how to achieve your requirements.
code :
state = {
  expanded: {},
};
this.setState(prevState => ({
  expanded: {
    ...prevState.expanded, // leave other panels expanded
    [tierOne.name]: true,
  },
}));
this.setState({
  expanded: {
    [tierOne.name] : true, // collapse all other panels
  }
})
if (state.expanded[tierOne.name]) this.setState({ expanded: {} });

Closing react-bootstrap popup modal by passing function from parent component to child component via props not updating


By : Sebastian
Date : March 29 2020, 07:55 AM
like below fixes the issue In togglePopup you use value from props, that is always undefined. You should use this.state.open
code :
togglePopup() {
    this.setState({
        open: !this.state.open
    });
}

react Portal - how to close modal when clicking outside of modal and how to assign ref to modal inside parent component


By : user3452325

fixed the issue. Will look into that further Since the click listener will be applied to all modal instances, I'd move the listener and the ref to a reuseable modal component -- now it'll control clicks once opened. The only thing it really needs is a passed down toggle modal function prop from the parent.
Working example:
code :
import React, { Fragment, PureComponent } from "react";
import { createPortal } from "react-dom";
import PropTypes from "prop-types";

class Modal extends PureComponent {
  componentDidMount() {
    document.addEventListener("click", this.closeModal, false);
  }

  componentWillUnmount() {
    document.removeEventListener("click", this.closeModal, false);
  }

  closeModal = ({ target }) => {
    if (this.modal && !this.modal.contains(target)) {
      this.props.toggleModal();
    }
  };

  render = () =>
    createPortal(
      <Fragment>
        <div className="overlay" />
        <div className="window-container">
          <div className="modal-container">
            <div ref={node => (this.modal = node)} className="modal">
              {this.props.children}
            </div>
          </div>
        </div>
      </Fragment>,
      document.body
    );
}

Modal.propTypes = {
  children: PropTypes.node.isRequired,
  toggleModal: PropTypes.func.isRequired
};

export default Modal;
import React, { Component } from "react";
import Modal from "../Modal";

class Parent extends Component {
  state = {
    showModal: false
  };

  toggleModal = () => {
    this.setState(prevState => ({
      showModal: !prevState.showModal
    }));
  };

  render = () => (
    <div className={`${this.state.showModal ? "blur" : undefined} app`}>
      <img
        src="https://i.imgur.com/BGwgr3A.jpg"
        className="image"
        alt="example.png"
        onClick={this.toggleModal}
      />
      {this.state.showModal && (
        <Modal toggleModal={this.toggleModal}>
          <h1 className="title">Hello!</h1>
          <p className="subtitle">There are two ways to close this modal</p>
          <ul>
            <li>Click outside of this modal in the grey overlay area.</li>
            <li>Click the close button below.</li>
          </ul>
          <button
            className="uk-button uk-button-danger uk-button-small"
            onClick={this.toggleModal}
          >
            Close
          </button>
        </Modal>
      )}
    </div>
  );
}

export default Parent;
