React Access parent component name

react call parent function from child

I want to get the parent component name inside the child component to display a error message when validating properties of that child component. I'm creating a reusable component, so anyone can use my component inside their components. When they are using my component I want to display warning messages with the name of the parent component.

Is there a specific method to get parent name in react. Any kind of help would be appreciated.

Children can see the context they are composed in through this._reactInternalInstance._currentElement._owner._instance.__proto__.constructor.name.

Used in the following way:

import React, { Component } from 'react';
class Warning extends Component {
  render() {
    return (
      <div> {"WARNING: " + this._reactInternalInstance._currentElement._owner._instance.__proto__.constructor.name + " has an error."}
      </div>
    )
  } 
}

export default Warning;

Do not believe this is parent child communication, it is like standing in a room and seeing from containing walls where you are.. this is not the container (parent) communicating to you (child) but rather the child being context aware.

Use this how you may, however do note that it is part of reacts internal instance and subject to change (do believe it is stable enough as of today).

How to get parent component's name in React?, While it's not clear how you'd use this with a Promise component you mentioned in a comment, you could try this: var componentName = this.constructor. The parent component displays an HTML table of data which gets retrieved from a PHP API backend and stored in a state variable named contacts. This is the example ContactForm child component: class ContactForm extends React.Component { state = { name: '', email: '',

you can get parent component from this._reactInternalFiber._debugOwner.type.name

You can access the parent node of a component using:

How to access value from parent method in child class in reactjs , How to access value from parent method in child class in reactjs I am not able to use props to access the date and month in child component render method. Accessing parent state in child in React. I have (e.g.) two components in React. The first, app.js, is the root component. It imports some JSON data and puts it in its state. This works fine (I can see it in the React devtools). The second, docs.js, is meant to show this JSON data.

React: Communication Between Components, Understand communication between React components: Render C is actually rendered in P, P is C's Parent component and C is the child component. So the C component can access the value of name in the props  class Child1 extends React.Component{sendData = => {this.props.parentCallback("Hey Popsie, How’s it going?");}, render() { //you can call function sendData whenever you'd like to send data from child component to Parent component.

Refs and the DOM – React, Refs provide a way to access DOM nodes or React elements created in the render In the typical React dataflow, props are the only way that parent components this alternative approach and explicitly pass a ref as a differently named prop. 1 Answer 1. active oldest votes. 45. It probably makes the most sense to pass it as a property, but if you really need to get it programmatically, and from inside the component, you can wait for the component to mount, find its DOM node, and then look at its parent.

Forwarding Refs – React, This way, components using FancyButton can get a ref to the underlying button DOM If you name the render function, DevTools will also include its name (e.g.​  Components can refer to other components in their output. This lets us use the same component abstraction for any level of detail. A button, a form, a dialog, a screen: in React apps, all those are commonly expressed as components. For example, we can create an App component that renders Welcome many times:

Comments
  • I'm not sure if this is necessarily better, but I'll post it here in case it helps someone out: this._reactInternalInstance._currentElement._owner.getName()
  • Just for notice: if you need to access to the parent component's name, it might will work only in the development stage, where your sources ain't got uglified via code compressors (ie. WebPack).
  • Can this way be used in prod? Is there any risk that the property will be lost?
  • I wouldn't recommend using it in production as it's react's internal properties.
