React data table component, passing info for clicked row into modal

Question

I'm making an offline PWA with ReactJS and I've started using the react-data-table-component, which has been great so far.

I've set the table to have an onRowClicked function that is called anytime a row is clicked, and so far, I only have that function opening a modal upon click which does indeed work.

My issue is that I want the modal to contain information from the row elements for the row that was clicked. So basically, if I click the first row that has the title "Hello There" (element.title) I want the modal to also contain the elements for that row.

This code shows everything I have, including how I'm mapping my documents from PouchDB into the elements object , which is what informs the rows in my data table.

What do I need to do in order to pass the info for the clicked row into the modal?

import React, { useState,useMemo} from 'react';
import { Column, Row } from 'simple-flexbox';
import { StyleSheet, css } from 'aphrodite/no-important';

const columns = [
  {
    name: 'Title',
    sortable: true,
    cell: row => (<div>{row.title}</div>),
  },
  {
    name: 'Date of Entry',
    selector: 'createdAt',
    sortable: true,
    right: true,
  },
];

class MedJournalComponent extends React.Component {

    constructor(props){
      super(props);
      this.state = {
        loading: true,
        elements: null,
        notebookDisplayOpen: false
      };

      this.fetchData.bind(this);
    }

    componentDidMount(){
      this.fetchData();
    }

    fetchData = () => {
      this.setState({
          loading: true,
          elements: null,
      });
      this.props.notes.db.allDocs({
          include_docs: true,
      }).then(result => {
          const rows = result.rows;
          this.setState({
              loading:false,
              elements: rows.map(row => row.doc),
          });
      }).catch((err) =>{
          console.log(err);
      });
    }

    notebookEntryHandler = () => {
      this.setState({notebookDisplayOpen: true});
    }

    closeNotebookEntry = () => {
      this.setState({notebookDisplayOpen: false});
    }

    render() {

        const { notebookDisplayOpen } = this.state;

        if (this.state.loading || this.state.elements === null) {
            return `loading...`;
        }
        return (
            <Column>

                <Modal open={notebookDisplayOpen} onClose={this.closeNotebookEntry}>
                    <div>Test</div>
                </Modal>

                <DataTable
                    title="Notebook Entries"
                    columns={columns}
                    data={this.state.elements}
                    theme="solarized"
                    selectableRows 
                    onRowClicked={this.notebookEntryHandler}
                    Clicked
                    Selected={handleChange}
                />

            </Column>
        );
    }
}

export default MedJournalComponent;

you can always search in rources ... https://github.com/jbetancur/react-data-table-component/blob/9cd157094a8cf14f59fe53c514a96f73070f0950/src/DataTable/DataTable.js#L131 ... as expected handler gets `row` — xadm, Mar 28 '20 at 00:31
Wait, I didn't see that anywhere for some reason. So I should be able to keep my onRowClicked line the way it is, but in the function I'm calling it should expect row by default? — Geoff_S, Mar 28 '20 at 00:45
it's logical, isn't it ? handler without that is unusable, not needed? — xadm, Mar 28 '20 at 00:48
@xadm I guess my question is how to access it in my function though? I'm a react noob still, so I'm just trying to figure out from that source, how can I access the row in my ```notebookEntryHandler```? — Geoff_S, Mar 28 '20 at 01:44

change:

notebookEntryHandler = () => {
  this.setState({notebookDisplayOpen: true});
}

to:

notebookEntryHandler = row => {
  this.setState({notebookDisplayOpen: true});
}

row represents the clicked row, you can store it in state and use it in the modal.

That got it, thanks! This makes more sense now as well after reading the source as @xadm pointed out – Geoff_S Mar 28 '20 at 03:24
