我正在开发一个基本上有两个流程的应用程序,分别是“ FLOW1”和“ FLOW2”。 有对应于每个流的路由。现在,我维护了一个开关,可以在流之间进行切换,相应地,页面也应该重定向。
FLOW1具有以下路由及其对应的组件:
F1R1:pageF1R1,
F1R2:pageF1R2,
F1R3:pageF1R3
FLOW2具有以下路由及其对应的组件:
F2R1:pageF2R1,
F2R2:pageF2R2,
F2R3:pageF2R3
这些路由是彼此相对的,每当我更改配置文件时,与更改后的流相对应的路由都应该更改。
所以我已经尝试过类似的事情,如果它有很多的话。有没有更好的方法可以实现?
navigate = (event) =>
{
let currentUrl = this.props.history.location.pathname;
let flow = event.target.name;
if(flow === "FLOW1")
{
if(currentUrl === "/F2R1")
this.props.history.push("/pageF1R1");
if(currentUrl === "/F2R2")
this.props.history.push("/pageF1R2");
if(currentUrl === "/F2R3")
this.props.history.push("/pageF1R3");
}
if(flow === "FLOW2")
{
if(currentUrl === "/F1R1")
this.props.history.push("/pageF2R1");
if(currentUrl === "/F1R2")
this.props.history.push("/pageF2R2");
if(currentUrl === "/F1R3")
this.props.history.push("/pageF2R3");
}
}

您可以使用react-router-dom
解决您的问题,这是基于您的想法的我的代码
我在这里只使用一个
/flow
网址,您可以使用以下链接创建您的网址: 尽可能
App.js
import React, { Component } from "react";
import { Route, Switch, Link } from "react-router-dom";
import Flow1 from "./flow1";
import Flow2 from "./flow2";
class App extends Component {
state = {
isFlow: true
};
handleChangeFlow = () => {
let isFlow = this.state.isFlow;
isFlow = !isFlow;
this.setState({ isFlow });
};
render() {
return (
<div>
<h1>welcome</h1>
<button onClick={this.handleChangeFlow}>Switch</button>
<Link to="/flow">Flow</Link>
<Switch>
<Route path="/flow" component={this.state.isFlow ? Flow1 : Flow2} />
</Switch>
</div>
);
}
}
export default App;
Flow1组件
import React from "react";
const Flow1 = () => {
return <h1>Flow-1</h1>;
};
export default Flow1;
和Flow2组件
import React from "react";
const Flow2 = () => {
return <h1>Flow-2</h1>;
};
export default Flow2;
更新:稍微动态的方式
render()部分,您必须先声明所有路由,然后根据您的URL进行声明,它将重定向到所需的页面
render() {
return (
<div>
<h1>welcome</h1>
<button onClick={this.handleChangeFlow}>Switch</button>
{this.state.navBars.map(n => (
<Link to={n.path}>{n.name}</Link>
))}
<Switch>
<Route path="/flow11" component={Flow1} />
<Route path="/flow12" component={Flow2} />
<Route path="/flow13" component={Flow3} />
<Route path="/flow21" component={Flow4} />
<Route path="/flow22" component={Flow5} />
<Route path="/flow23" component={Flow6} />
</Switch>
</div>
);
}
更改状态
state = {
isFlow: true,
navBars: []
};
handleChangeFlow
handleChangeFlow = () => {
let isFlow = this.state.isFlow;
isFlow = !isFlow;
this.setState({ isFlow, navBars: this.getNavBars(this.state.isFlow) });
};
新添加的方法getNavBars,您也从数据库中填充了该数组
getNavBars = isFlow => {
return isFlow
? [
{ name: "Flow1", path: "/flow11" },
{ name: "Flow2", path: "/flow12" },
{ name: "Flow3", path: "/flow13" }
]
: [
{ name: "Flow1", path: "/flow21" },
{ name: "Flow2", path: "/flow22" },
{ name: "Flow3", path: "/flow23" }
];
};
我在这里添加了componentDidMount
componentDidMount() {
this.setState({ navBars: this.getNavBars(this.state.isFlow) });
}
最后,您必须对index.js进行更改。您必须用
包装组件<BrowserRouter>
<App />
</BrowserRouter>
