创建一个有状态组件
提示1:
class StatefulComponent extends React.Component {
constructor(props) {
super(props);
// initialize state here
// "This" area may be a good place to use "dot" notation.
// dont forget to describe "name" property inside the state and assign your name to a property of "name".
}
render() {
return (
<div>
<h1>{this.state.name}</h1>
</div>
);
}
};
解
class StatefulComponent extends React.Component {
constructor(props) {
super(props);
// initialize state here
this.state = {
name : "Name"
}
}
render() {
return (
<div>
<h1>{this.state.name}</h1>
</div>
);
}
};
