React-router-如何在React中的页面之间传递数据? [英] React-router - How to pass data between pages in React?
问题描述
我正在一个项目中,我必须将数据从一页传递到另一页.例如,我在第一页上有 data
.
I am working on a project where I have to pass data from one page to another.
For example, I have data
on the first page.
let data = [
{id:1, name:'Ford', color:'Red'},
{id:2, name:'Hyundai', color:'Blue'}
]
这是第一个组件页面,我在其中显示此名称的数据列表.
Here is the first component page where I render this list of data with the name.
class ListDetail extends Component {
constructor();
handleClick(data){
console.log(data);
}
render() {
return (
<div>
<Hello name={this.state.name} />
<ul>
{data.map((data,i) => {
return <li onClick={this.handleClick.bind(this,data)}>{data.name}</li>
})}
</ul>
</div>
);
}
}
我想将此数据传递到下一个页面,在该页面上我需要该数据以及比此更多的数据.我正在使用React Router4.任何建议或帮助都会有所帮助.
I want to pass this data to the next page where I need this data and more data than this. I am using React Router 4. Any suggestion or help would be helpful.
推荐答案
您可以使用react-router中的Link组件并将 to = {}
指定为对象,并在其中将路径名指定为路由要去.然后添加一个变量,例如 data
保存要传递的值.请参见下面的示例.
You can use the Link component from react-router and specify to={}
as an object where you specify pathname as the route to go to. Then add a variable e.g. data
to hold the value you want to pass on. See the example below.
使用< Link/>
组件:
<Link
to={{
pathname: "/page",
state: data // your data array of objects
}}
>
使用 history.push()
this.props.history.push({
pathname: '/page',
state: data // your data array of objects
})
使用上述两个选项之一,您现在可以按照页面组件中的以下内容访问位置对象上的 data
.
Using either of the above options you can now access data
on the location object as per the below in your page component.
render() {
const { state } = this.props.location
return (
// render logic here
)
}
在另一个示例此处中,您可以看到一个如何将值与路由一起传递的示例.
