React getting access to properties of list component on click


By : CaseyQueso
Date : September 16 2020, 12:00 AM
it helps some times You aren't passing the id to the Seat component. So it makes sense why this.props.id is not there.
Either pass the id to the component:
code :
<Seat 
  id={seat._id} 
  onClick={this.handleClick.bind(this)} 
  key={seat._id} 
  value={seat._id} 
  ticket={seat.ticket} 
  seat={seat}
/>
this.setState({seatId: this.props.value})

React: how to access component function from a click event on vis.js edge?


By : user1569745

this one helps. You can change the function given to selectEdge to an arrow function to use the enclosing lexical scope instead, which has _openDialog on this.
code :
export default class App extends Component {
  // ...

  render() {
    return (
      <div>
        <div className="tree_graph_div">
          <Graph
            graph={graph}
            events={{
              selectEdge: (event) => {
                var { nodes, edges } = event;
                if (edges.length == 1) {
                  this._openDialog(edges);
                }
              }
            }}
          />
        </div>
        <div>
          <Dialog />
        </div>
      </div>
    );
  }
}

How to access properties of objects from a third-party DOM library used in a React component from the outside


By : user1964143

I hope this helps you . Actually the flow should be the other way round, define the nodes outside of the component, then pass them in. For that define the constructor as:
code :
 constructor(props) {
    super(props);
    this.nodes = props.nodes;
    //...
}
 const nodes = new DataSet([/*...*/]);
 ReactDOM.render(<VisNetwork nodes={nodes} />,document.getElementById('mynetwork'));

Detect click outside a component react way NOT dom access


By : Ray Hyde

this one helps. If you really, really don't want to attach dom events to your components, you can add a 'dismisser' component behind the Crop component and handle the reset there.
code :
const Dismisser = ({ onClick }) => <div onClick={onClick} style={{
  position: 'fixed',
  top: 0, left: 0, right: 0, bottom: 0,
  zIndex: 100,
}} />
{src && (
  <React.Fragment>
  <div style={{position: 'relative', zIndex: 200}}>
    <ReactCrop
      src={src}
      crop={crop}
      ...
    />
  </div>
  <Dismisser onClick={this.resetCrop} />
  </React.Fragment>
)}

How to access react-list getVisibleRange() within a functional component


By : user3190353
Date : March 29 2020, 07:55 AM
will help you You need to access it through a reference, with hooks you may use useRef:
code :
const TalentSearch = () => {
  const listRef = useRef();
  return <ReactList ref={listRef} />;
};
listRef.current.getVisibleRange();

How to access method of another component on button click in React?


By : user3394988
Date : March 29 2020, 07:55 AM
it helps some times Generally, you're going to want to "lift" state up to a common ancestor. I took your code below and lifted state to a common "App" ancestor.
code :
class IncreaseDiceButton extends React.Component {
  render () {
    return (
      <button onClick={props.incrementState}>
        Increase Number Of Dice
      </button>
    );
  }
};
class NumDice extends React.Component { 
  render() {
    return (
      <h2>
        {props.mystate}
      </h2>
    );  
  }
};
class App extends React.Component {
  constructor () {
    super();
    this.state = { mystate: 1 }; 
  }

  incrementState = () => {
    var myNewState = this.state.mystate +1;
    this.setState({mystate: myNewState});
  };

  decrementState = () => {
    var myNewState = this.state.mystate -1;
    if(myNewState > 0){
      this.setState({mystate: myNewState});
    }
  }

  render() {
    return (
      <NumDice mystate={this.state.mystate} />
      <IncreaseDiceButton incrementState={incrementState} />
    )
  }
}
