我已经获得了路由器链接并将图像插入其中。图像显示一切都很好。但是，

我的问题是，当我单击第二个路由器链接时，我想将第二个routerlink图像转换为第一个路由器链接图像，并将第一个路由器链接图像转换为第二个routerlink图像。

试图在切换的帮助下解决此代码，但无法正常工作，我对此任务感到担心。

import eligibilitypng from "C:/Users/DHANUNJAY/datri/src/validatemoilenumberpng.png.";
import validatemoilenumberpng from "C:/Users/DHANUNJAY/datri/src/eligibilitypng.png";


<li onClick={this.toggleImage}>{this.state.open ? <img src={eligibilitypng} /> : <img src={validatemoilenumberpng } />}</li>

在reactjs中更改图像onclick
