[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
我已经建立了一个网站来响应。 我的代码在这里https://codesandbox.io/s/3d-tool-zjm5m?file=/src/components/modeling.jsx 。 我想要的是当用户点击 Modeling 选项卡中的“Go upload”按钮时,它会链接到一个新的 upload.jsx 页面,并且仍然有导航栏。
App.js 代码:
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 代码:
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!
您的导航栏具有指向“主页”部分的哈希链接。 当您引入应用导航并且想要多个页面时,您应该使用Link
组件而不是锚标记。 您还需要将Navigation
组件放置在路由上,以便它可以访问Router
上下文。
由于您已经将整个应用程序包装在Router
您只需将Navigation
和“主页”组件放在Route
。 将“主页”组件渲染为匿名组件,并记住将路由道具传递给每个组件。
<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>
为了保持 hashlink 功能正常工作,您还需要从其他页面导入HashLink
组件。
import { HashLink } from "react-router-hash-link";
并将所有锚标签更改为HashLink
组件。
<HashLink className="navbar-brand page-scroll" to="/#page-top">
3D RECONSTRUCTION TOOL
</HashLink>{" "}
...
<HashLink to="/#page-top" className="page-scroll">
Home
</HashLink>
// ...etc...
修复按钮的onClick
属性,它是onClick
而不是onclick
。 因为路由道具是从App.js
,所以history
道具现在可用于命令式导航。
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>
现在您可能会注意到,当导航到“/upload”上的新页面时,导航标题仍然固定在窗口的顶部,而页面呈现在下方。 这是从react-bootstrap
应用的样式。 要解决此问题,您可以向正文添加padding-top
以将内容下推到标题下。
body {
padding-top: /* whatever the navigation header height is */;
}
不过,您的标题是动态的,具体取决于视图宽度,因此您可能需要检查视图宽度并在 JS 中进行设置。 这是一个很有前途的解决方案: https : //stackoverflow.com/a/38105035/8690857
