在React + ES6中重置初始状态

您可以使用getter函数：

class ElementBuilder extends Component {  constructor(props) {    super(props);    this.state = this.initialState;  }  get initialState() {    return {      title: 'Testing',      size: 100,      color: '#4d96ce',    };  }  resetBuilder() {    this.setState(this.initialState);  }}

或只是一个变量：

constructor(props) {  super(props);  this.initialState = {    title: 'Testing',    size: 100,    color: '#4d96ce',  };  this.state = this.initialState;}
