[React] React Fundamentals: Owner Ownee Relationship
The owner-ownee relationship is used to designate a parent-child relationship with React components as it differs from the DOM relationship.
When one component renders another component, this is what React refers to as the "owner-ownee relationship," where the parent component is also called a "composite component."
We are going to create a component call 'Widget' which will be used inside our 'React_app' component.
'Widget' doesn't have any state, all it has is from 'React_app' pass into it.
<Widget update={this.myUpdate} name={this.state.name}></Widget>
Example:
<!DOCTYPE html> <html> <head lang="en"> <meta charset="UTF-8"> <title>React Lesson 4: Onwer - Ownee</title> </head> <body> <script src="https://cdnjs.cloudflare.com/ajax/libs/react/0.12.2/react.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/react/0.12.2/JSXTransformer.js"></script> <script type="text/jsx"> var React_app = React.createClass({ getInitialState: function() { return { name: "Joe" } }, myUpdate: function(e){ this.replaceState({name: e.target.value}); }, render: function() { return ( <div> <Widget update={this.myUpdate} name={this.state.name}></Widget> <Widget update={this.myUpdate} name={this.state.name}></Widget> <Widget update={this.myUpdate} name={this.state.name}></Widget> <Widget update={this.myUpdate} name={this.state.name}></Widget> <Widget update={this.myUpdate} name={this.state.name}></Widget> </div> ); } }); var Widget = React.createClass({ render: function(){ return ( <div> Your name: <input type="text" onChange={this.props.update}/> <h1>{this.props.name}</h1> </div> ) } }); React.render(<React_app />, document.body); </script> </body> </html>
