React-Router和iframe，浏览器历史记录

Question

I came to the kind of anyoing problem. So, I have a component in react and also using react-router . Everything works almost great. This component has a list of items, when you click on one, it pushes url to the iframe[src={url}] . And here appears the problem, if I will click on several items and then click on the previous page/back button, instead of going to the previous page, it just shows the previous iframe of url that was pushed to iframe.

What do I do in this situation?

@I'm using react-router-dom v4

Don't just change the src. You've to replace a new iframe everytime the src change. By doing that without change things much, just add difference key to your iframe everytime you change src

render(){
const iframe = <iframe key={this.thing.id} src={this.thing.src} ></iframe>
return(iframe)
}
