我的代码有问题:
class Note extends React.Component{
constructor(props){
super(props);
}
xoa(){
var {index, handleRemove} = this.props;
handleRemove(index);
}
render(){
return(
<div>
<p>{this.props.children}</p>
<button onClick={this.xoa.bind(this)}> Delete </button>
</div>
);
}
}
class List extends React.Component{
constructor(props){
super(props);
this.state = {
arrayNote: ['ha', 'hi', 'hu']
};
}
remove(index){
this.state.arrayNote.splice(index, 1);
this.setState(this.state);
}
render(){
this.remove = this.remove.bind(this);
return(
<div>{this.state.arrayNote.map(function(note, i){
return (<Note index={i}
handleRemove={this.remove}
key={i}>{note}</Note>)
})}
</div>
);
}
}
ReactDOM.render(
<List />,
document.getElementById("root")
);
<div id="root"></div>
