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,但是我在方法中遇到错误,说'' js [;]期望'或要求以这种方式宣布课程:
导出默认类Landing扩展了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
};
答案 0 :(得分:0)
您声明了组件时出错了,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
};
