React.js:如何使用两个不同的独立 Button 组件下载两个不同的文件?

[英]React.js: How can I download two different files with two different separate Button components?

I have got two buttons as components that need to download two different files, but so far both buttons download the same file that is no surprise for me.我有两个按钮作为需要下载两个不同文件的组件,但到目前为止,这两个按钮都下载同一个文件,这对我来说并不奇怪。 I have tried different solutions, with useState() and without, but none of them seem to be working.我尝试了不同的解决方案,使用 useState() 和不使用,但似乎都没有用。 I know I am missing logic here, but I do not understand where I am missing it.我知道我在这里缺少逻辑,但我不明白我在哪里缺少它。 How do I download a different file when clicking the first button, and download another file when clicking on another button?如何在单击第一个按钮时下载不同的文件,然后在单击另一个按钮时下载另一个文件? Should there be something that I should recap on, too?我也应该回顾一下吗?

Here is the code:这是代码:

Hero.js (Parent component) Hero.js(父组件)

import Button from "../../components/UI/Button/Button";

const Hero = () => {

  return (
    <div>
      <div>
        <Button>CV (English)</Button>
        <Button>CV (Another Language)</Button>
      </div>
    </div>
  );
};

export default Hero;

Button.js (Child component) Button.js(子组件)

import cv from "../../../assets/files/CV English.pdf";
import anotherLanguage from "../../../assets/files/anotherLanguage.pdf";

const Button = (props) => {
  const file = cv;

  return (
    <button>
      {file === cv ? (
        <a href={cv} download="CV English">
          {props.children}
        </a>
      ) : (
        <a href={anotherLanguage} download="CV Another Language">
          {props.children}
        </a>
      )}
    </button>
  );
};

export default Button;

You could pass a language prop to the button like this:您可以像这样将语言道具传递给按钮:

      <div>
        <Button language="en">CV (English)</Button>
        <Button>CV (Another Language)</Button>
      </div>

And then use it in the Button component like this:然后像这样在 Button 组件中使用它:

import cv from "../../../assets/files/CV English.pdf";
import anotherLanguage from "../../../assets/files/anotherLanguage.pdf";

const Button = (props) => {
  const file = cv;

  return (
    <button>
      {props.language === "en" ? (
        <a href={cv} download="CV English">
          {props.children}
        </a>
      ) : (
        <a href={anotherLanguage} download="CV Another Language">
          {props.children}
        </a>
      )}
    </button>
  );
};

export default Button;
