下面是来自App.js的代码段,其中包括Navigator
组件:
class App extends Component {
constructor(props) {
super(props);
}
render() {
return (
<Router>
<div>
<HeaderAmex className="App" />
<div>
<Navigation/>
</div>
<Route exact path="/invoice" component={Invoice} />
</div>
</Router>
);
}
}
export default withRouter(App)
我的导航组件如下所示。它获取位置作为属性:
class Navigation extends Component {
render() {
const { match, location, history } = this.props
return (
<Router>
<nav className="navbar navbar-expand-lg navbar-light bg-light">
<button
className="navbar-toggler"
type="button"
data-toggle="collapse"
data-target="#navbarSupportedContent"
aria-controls="navbarSupportedContent"
aria-expanded="false"
aria-label="Toggle navigation"
>
<span className="navbar-toggler-icon"></span>
</button>
<div className="collapse navbar-collapse" id="navbarSupportedContent">
<ul className="navbar-nav mr-auto">
<NavDropdown name="Test">
<a className="dropdown-item" >
<li><Link to={"/Invoice"} >Mexico Invoice</Link></li>
</a>
</NavDropdown>
<NavDropdown name="Analysis">
<a className="dropdown-item" href="/Transaction">Audit Log</a>
</NavDropdown>
</ul>
<Route exact path="/Invoice" component={Invoice} />
</div>
</nav>
</Router>
);
}
}
export default withRouter(Navigation)
下面是Invoice.js中的代码
render() {
const { match, location, history } = this.props
console.log("---------------------------"+this.state.invoicedisplayFlag);
return (
<div className="App">
<br/>
<label className="lable" style={{marginRight:19}}>
InvoiceXml:
<input
type="text"
name="invoiceXml"
placeholder="Enter invoice xml"
onBlur={this.handleChangeInvoice.bind(this)}
style={{marginLeft:15}}
/>
</label>
<br/>
<input
type="button"
onClick={this.handleSubmitInvoiceXml}
name="Submit"
value="Submit"
className="submitButton"
style={{marginLeft:-60}}
/>
<br/>
<div className={this.state.invoicedisplayFlag ? "showDisplay" : "hide"}>
<h5>Transaction Id is :{this.state.invoiceTransId}</h5>
</div>
</div>
);
}
我遇到了错误:
"TypeError: Cannot read property 'location' of undefined" at Router.js:66
我已尝试针对此问题列出多种方法,但没有任何方法解决我的错误。有人可以帮我吗?

欢迎来到stackoverflow,
我不确定我是否正确理解了您的问题,因为您大多在显示代码,但没有具体说明发生错误的情况或位置。
我看到的是,您正在通过Invoice
属性将component
组件传递给路由。读完this github post后,看来在react-router v4中,您应该使用render
属性将道具和您的组件一起移交。
所以基本上您应该做的是:
创建一个将props作为参数并返回具有所需props的Invoice组件的函数
在Navigator.js中将<Route exact path="/Invoice" component={Invoice} />
更改为<Route exact path="/Invoice" render={MyInvoiceFunction} />
请记住,为您的下一个问题提供更多信息和格式正确的代码;)
希望这可以解决您的问题
编辑:
您应该将该函数添加到Invoice.js中,例如:
export const MyInvoiceFunction = (props) => {
return (
<Invoice match={this.match.bind(this)} location={this.location.bind(this)} {...props} />
);
};
