React中传参方式有很多，通过路由传参的方式也是必不可少的一种。
本文记录项目中会用到的路由传参方式： 路由跳转传参API + 目标路由获取参数的方式。
一、动态路由
跳转方法
Link
<Link to={{ pathname: "/user/add/1" }}>跳转新增页面</Link>
history.push
this.props.history.push("/user/add/1");
获参方法
this.props.match.params
二、路由query显示参数
Link跳转
<Link to={{ pathname: "/user/add", query: { id: 1 } }}>
跳转新增页面
</Link>
history.push
this.props.history.push({
pathname: "/user/add",
//参数
query: { id: 1 },
});
获参方法
this.props.location.query
三、路由state隐式参数
Link跳转
<Link to={{ pathname: "/user/add", state: { id: 1 } }}>
跳转新增页面
</Link>
history.push
this.props.history.push({
pathname: "/user/add",
state: { id: 1 },
});
获参方法
this.props.location.state
代码DEMO
入口App组件
class App extends React.Component {
render() {
return (
<BrowserRouter>
<Route path="/user" exact component={User} />
//动态路由
<Route path="/user/add/:id?" component={UserAdd} />
{/* <Redirect to="/user" /> */}
</BrowserRouter>
);
}
}
动态路由Demo
User组件
import React, { Component } from "react";
import { Link } from "react-router-dom";
export default class User extends Component {
render() {
return (
<div>
<div className="user">User</div>
{/* <Link to={{ pathname: "/user/add/1" }}>跳转新增页面</Link> */}
<button
onClick={() => {
// 1.
// this.props.history.push("/user/add/1");
// 2.
this.props.history.push({
pathname: "/user/add/1",
});
}}
>
跳转新增页面
</button>
</div>
);
}
}
UserAdd组件
import React, { Component } from "react";
export default class UserAdd extends Component {
render() {
console.log("this.props.match.params:", this.props.match.params);
return <div>UserAdd</div>;
}
}
路由query显示参数Demo
User组件
import React, { Component } from "react";
import { Link } from "react-router-dom";
export default class User extends Component {
render() {
return (
<div>
<div className="user">User</div>
<Link to={{ pathname: "/user/add", query: { id: 1 } }}>
跳转新增页面
</Link>
<button
onClick={() => {
this.props.history.push({
pathname: "/user/add",
query: { id: 1 },
});
}}
>
跳转新增页面
</button>
</div>
);
}
}
路由state隐式参数Demo
User组件
import React, { Component } from "react";
import { Link } from "react-router-dom";
export default class User extends Component {
render() {
return (
<div>
<div className="user">User</div>
<Link to={{ pathname: "/user/add", state: { id: 1 } }}>
跳转新增页面
</Link>
<button
onClick={() => {
this.props.history.push({
pathname: "/user/add",
state: { id: 1 },
});
}}
>
跳转新增页面
</button>
</div>
);
}
}
