在React Component中渲染脚本标签 [英] Render script tag in React Component

问题描述

我正在制作一个React应用程序，我只需要在一个组件中运行Javascript脚本，并引用div之一.

I'm making a React application and I need to run a Javascript script only in one component, making reference to one of the div's.

我知道有一些这样做的库，但是我想知道是否有更直接的方法来做到这一点.现在，我这样做:

I know there are some libraries to do so, but I wonder if there's a more direct way to do it. Right now I do this:

import React, { Component } from "react";
import "../ThisComponent.css";

export default class MyComponent extends Component {
  render() {
    return (
      <div>
        <div id="scriptTarget" />
        <div className="main">
          // Other stuff
        </div>
        <script src="js/myScript.js" />
      </div>
    );
  }
}

但是什么也没发生.脚本存储在public/js/myScript.js中.
谢谢！

But nothing happens. The script is stored in public/js/myScript.js.
Thanks!

推荐答案

我最终在渲染组件之前通过添加componentDidMount函数解决了它.像这样:

I finally solved it by adding the componentDidMount function before rendering the component. Like this:

import React, { Component } from "react";
import "../ThisComponent.css";

export default class MyComponent extends Component {
  componentDidMount() {
    const script = document.createElement("script");

    script.src = "js/myScript.js";
    script.async = true;

    document.body.appendChild(script);
  }

  render() {
    return (
      <div>
        <div id="scriptTarget" />
        <div className="main">
          // Other stuff
        </div>
      </div>
    );
  }
}
