antd表单校验按钮置灰

1.初始置灰

componentDidMount() {
    // To disabled submit button at the beginning.
    this.props.form.validateFields();
  }

2.置灰不显示报错

判断是否有错和输入框是否有空

  hasErrors = (fieldsError) => {
    return Object.keys(fieldsError).some(field => fieldsError[field])
    ||Object.keys(this.props.form.getFieldsValue()).some(field => this.props.form.getFieldsValue()[field]===undefined);
  }

Object.key()
Array.some()
