reactjs状态setstate问题

Question

我有一个Submit form方法，该方法看起来很正常，但是会发出警告，我想知道为什么？ 警告是“ warning.js？6327：33警告：setState（...）：只能更新已安装或正在安装的组件。这通常意味着您在未安装的组件上调用了setState（）。这是空操作。请“

constructor(props) {
super(props);
this.handleForm = this.handleForm.bind(this);
this.handleState = this.handleState.bind(this);
this.submitForm = this.submitForm.bind(this);
this.submitButton = null;
let form = null;
if (props.node !== null) {
  form = { ...props.node };
} else {
  form = {
    name: null,
    description: null,
    enabled: null,
    cost: null,
    thumbnail: null,
    image: null,
    grants: []
  };
}
this.state = {
  isLoading: false,
  success: null,
  form: form,
  errorMessages: null,
  invalid: {
    name: false,
    description: false,
    enabled: false,
    cost: false,
    thumbnail: false,
    image: false,
    grants: false
  }
};

}

 async handleForm(event) {
event.preventDefault();
if (!this.refs.form || this.refs.form.checkValidity()) {
  try {
    let result = null;
    let serviceId;
    if (this.state.form.id) {
      result = await editMutation(
        this.state.form.id,
        this.state.form.name,
        this.state.form.description,
        this.state.form.enabled,
        this.state.form.cost,
        this.state.form.thumbnail,
        this.state.form.image,
        this.state.form.grants
      );
      serviceId = result.serviceEditMutation.service.id;
    } else {
      result = await addMutation(
        this.state.form.name,
        this.state.form.description,
        this.state.form.enabled,
        this.state.form.cost,
        this.state.form.thumbnail,
        this.state.form.image,
        this.state.form.grants
      );
      serviceId = result.serviceAddMutation.service.id;
    }
    serviceIdAction.serviceAction(serviceId);
    this.setState({ success: true });
  } catch (e) {
    this.setState({ success: false, errorMessages: e });
  }
}

}
