[英]How can I get a button to link to a new page, and have a search bar pre filled
[英]How to link 2 components in React and in a new page still have a navigation bar
我已經建立了一個網站來響應。 我的代碼在這里https://codesandbox.io/s/3d-tool-zjm5m?file=/src/components/modeling.jsx 。 我想要的是當用戶點擊 Modeling 選項卡中的“Go upload”按鈕時,它會鏈接到一個新的 upload.jsx 頁面,並且仍然有導航欄。
App.js 代碼:
import React, { Component } from 'react'
import Navigation from './components/navigation';
import Header from './components/header';
import About from './components/about';
import Modeling from './components/modeling';
import Resources from './components/resources';
import Team from './components/Team';
import JsonData from './data/data.json';
export class App extends Component {
state = {
landingPageData: {},
}
getlandingPageData() {
this.setState({landingPageData : JsonData})
}
componentDidMount() {
this.getlandingPageData();
}
render() {
return (
<div>
<Navigation />
<Header data={this.state.landingPageData.Header} />
<About data={this.state.landingPageData.About} />
<Modeling data={this.state.landingPageData.Modeling} />
<Resources data={this.state.landingPageData.Resources} />
<Team data={this.state.landingPageData.Team} />
</div>
)
}
}
export default App;
Modeling.jsx 代碼:
import React, { Component } from "react";
import Upload from "./upload";
export class Modeling extends Component {
uploadButton = (event) => {
event.preventDefault();
this.props.history.push({
pathname: "/upload"
});
};
render() {
return (
<div id="modeling">
<div className="container">
<div className="row">
<div className="about-text">
<h2>3D MODELING</h2>
</div>
</div>
<div className=" wow fadeInUp slow">
<div className="row pt-5 justify-content-center">
<div className="col text-center">
<h1>
<b>Pick what's right for you </b>
</h1>
</div>
</div>
</div>
<div class="row p-5 p-md-0 pt-md-5 justify-content-around">
<div
class="col-md-5 mb-4 m-md-0 ml-md-5 modern-card card card-body shadow text-center wow fadeIn slow"
data-wow-delay="0.2s"
>
<h2 class="mb-3 blue">
<b>A 3D model from a 2D image.</b>
</h2>
<button
type="button"
class="btn btn-primary go-button"
onclick={this.uploadButton}
>
Go upload
</button>
</div>
<div
class="col-md-5 mr-md-5 modern-card card card-body shadow text-center wow fadeIn slow"
data-wow-delay="0.4s"
>
<h2 class="mb-3 blue">
<b>A virtual tour from a 3D model.</b>
</h2>
<button
type="button"
class="btn btn-primary go-button"
>
Go!
</button>
</div>
</div>
</div>
</div>
);
}
}
export default Modeling;
Can someone stop by give me any suggestions? I have really appreciated it. Thanks!
您的導航欄具有指向“主頁”部分的哈希鏈接。 當您引入應用導航並且想要多個頁面時,您應該使用Link
組件而不是錨標記。 您還需要將Navigation
組件放置在路由上,以便它可以訪問Router
上下文。
由於您已經將整個應用程序包裝在Router
您只需將Navigation
和“主頁”組件放在Route
。 將“主頁”組件渲染為匿名組件,並記住將路由道具傳遞給每個組件。
<div>
<Route component={Navigation} />
<Switch>
<Route path="/upload" component={Upload} />
<Route
render={(routeProps) => (
<>
<Header {...routeProps} data={this.state.landingPageData.Header} />
<About {...routeProps} data={this.state.landingPageData.About} />
<Modeling {...routeProps} data={this.state.landingPageData.Modeling} />
<Resources {...routeProps} data={this.state.landingPageData.Resources} />
<Team {...routeProps} data={this.state.landingPageData.Team} />
</>
)}
/>
</Switch>
</div>
為了保持 hashlink 功能正常工作,您還需要從其他頁面導入HashLink
組件。
import { HashLink } from "react-router-hash-link";
並將所有錨標簽更改為HashLink
組件。
<HashLink className="navbar-brand page-scroll" to="/#page-top">
3D RECONSTRUCTION TOOL
</HashLink>{" "}
...
<HashLink to="/#page-top" className="page-scroll">
Home
</HashLink>
// ...etc...
修復按鈕的onClick
屬性,它是onClick
而不是onclick
。 因為路由道具是從App.js
,所以history
道具現在可用於命令式導航。
uploadButton = (event) => {
event.preventDefault();
this.props.history.push({
pathname: "/upload"
});
};
...
<button
type="button"
className="btn btn-primary go-button"
onClick={this.uploadButton}
>
Go upload
</button>
現在您可能會注意到,當導航到“/upload”上的新頁面時,導航標題仍然固定在窗口的頂部,而頁面呈現在下方。 這是從react-bootstrap
應用的樣式。 要解決此問題,您可以向正文添加padding-top
以將內容下推到標題下。
body {
padding-top: /* whatever the navigation header height is */;
}
不過,您的標題是動態的,具體取決於視圖寬度,因此您可能需要檢查視圖寬度並在 JS 中進行設置。 這是一個很有前途的解決方案: https : //stackoverflow.com/a/38105035/8690857
