我可以在常量内声明一个 Meteor onLogout 方法吗?

I can declare a method Meteor onLogout within a constant?

我可以在常量中声明一个方法,我尝试在导航栏中实现 onLogout 方法,但我在方法中遇到错误,说 'js [;] expected' 或要求在此声明 class方式:

export default class Landing extends React.Component

import React from 'react';
import {Link} from 'react-router'
import { Accounts } from 'meteor/accounts-base';

const NavbarLanding = () => {
  onLogout() {
    Meteor.logout();
  };
  return (
    <div className="navbar-landing">
      <nav>
        <div>
          <ul className="ul-landing">
            <img src="/images/fly_paper.svg"></img>
            <li className="navbar-title"><a>Landing</a></li>
 {/* <img border="0" height="40" hspace="0" src="/images/fly_paper.png" width="80" /> */}
 {/* onClick={this.onLogout.bind(this) */}
 {/* btn-primary */}
            <div className="navbar-menu">
              <li><a>acerca</a></li>
              <li><a>portafolio</a></li>
              <li><a>contacto</a></li>

              <button className="btn"onClick={this.onLogout.bind(this)}>Logout</button>
            </div>
          </ul>
        </div>
      </nav>
    </div>
  );
};

export default NavbarLanding;

NavbarLanding.reactProptype = {
  title: React.PropTypes.string.isRequired
};

您在声明组件时出错,它应该是这样的:

export default class NavbarLanding extends React.Component {
  onLogout() {
    Meteor.logout();
  }

  render() {
    return (
      // your html here
    );
  }
};

NavbarLanding.reactProptype = {
  title: React.PropTypes.string.isRequired
};
