将反应图标动态添加到组件中的导航栏项目

Question

请耐心等待，我正在学习 React，所以我是初学者。我正在尝试创建一个底部导航面板。我没有对每个导航栏元素进行硬编码，而是找到了将导航栏元素存储在数组中然后将其映射到导航栏的好示例。我已经得到了下面的工作，除了我不确定如何在组件本身内动态引用我的 navTabs 数组中的图标？我可以毫无问题地添加（例如）<FaIdCard />，但我不想对此进行硬编码，因为它会破坏从数组生成导航的意义。

import React from 'react';
import { Nav, NavItem} from 'reactstrap';
import { NavLink } from 'react-router-dom';
import { FaIdCard, FaInfoCircle } from "react-icons/fa";


/* This array will be mapped onto our nav elements */
const navTabs = [{
    route: "/about",
    icon: FaInfoCircle,
    label: "About"
},{
    route: "/customer",
    icon: FaIdCard,
    label: "Customer"      
}]

const Navigation = (props) => {
    return (
        <div>
            <nav className="navbar fixed-bottom navbar-light" role="navigation">
                <Nav className="w-100">
                    <div className="d-flex flex-row justify-content-around w-100">
                        { 
                        /*  index is a built-in part of .map that gives u index number. 
                            The grave accent (`) is used for template literals, or combining variables, javascript and text/html
                        */
                            navTabs.map((tab, index) =>(
                                <NavItem key={`tab-${index}`}> 
                                    <NavLink to={tab.route} className="nav-link" activeClassName="active">
                                        <div className="row d-flex flex-column justify-content-center align-items-center">
                                            <div>{tab.label}</div>
                                        </div>
                                    </NavLink>
                                </NavItem>
                            ))
                        }
                    </div>
                </Nav>
            </nav>
        </div>
    )
  };
  
  export default Navigation;

尝试使用您的图标组件 icon 属性:

const navTabs = [{
    route: "/about",
    icon: <FaInfoCircle />,
    label: "About"
},{
    route: "/customer",
    icon: <FaIdCard />,
    label: "Customer"      
}]

然后像这样将其添加到 NavItem 中：

<NavItem key={`tab-${index}`}>
  <NavLink to={tab.route} className='nav-link' activeClassName='active'>
    <div className='row d-flex flex-column justify-content-center align-items-center'>
      <div>
        {tab.icon} {tab.label}
      </div>
    </div>
  </NavLink>
</NavItem>;
