我正在尝试在代码中的<DropdownLink />
内执行<BootstrapDropdown />
,但是我不知道该怎么做。
我试图用React文档解决问题,但是什么也没找到。
App.js
import React from 'react';
import '../scss/app.scss';
import BootstrapDropdown from './helpers/bootstrapDropdown';
import DropdownLink from './helpers/dropdownLink';
function App() {
return (
<div className="App">
<BootstrapDropdown name={"Dropdown"}>
<DropdownLink name={"Strona główna"} href={"/"} />
</BootstrapDropdown>
</div>
);
}
export default App;
dropdownLink.js
import React from 'react';
class DropdownLink extends React.Component {
render() {
return <a className="dropdown-item" href={this.props.href}>{this.props.name}</a>
}
}
export default DropdownLink;
bootstrapDropdown.js
import React from 'react';
class BootstrapDropdown extends React.Component {
render() {
return <div className="dropdown">
<button className="btn btn-secondary dropdown-toggle" type="button" id="dropdown" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
{this.props.name}
</button>
<div className="dropdown-menu" aria-labelledby="dropdownMenuButton">
</div>
</div>
}
}
export default BootstrapDropdown;
我想在<DropdownLink />
中的<div className="dropdown-menu"></div>
内显示<BootstrapDropdown />
。

您需要明确说明在何处渲染子代:
import React from 'react';
class BootstrapDropdown extends React.Component {
render() {
return <div className="dropdown">
<button className="btn btn-secondary dropdown-toggle" type="button" id="dropdown" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
{this.props.name}
</button>
<div className="dropdown-menu" aria-labelledby="dropdownMenuButton">
{this.props.children}
</div>
</div>
}
}
export default BootstrapDropdown;
