               </script>
            <a id="OpenDialog" href="#">Click here to open dialog</a>

I think you have wrong understanding of how react works, since you are using plain html to build what you are showing here.我认为您对 react 的工作原理有错误的理解，因为您使用普通的 html 来构建您在此处显示的内容。 First google "create react app", react uses JSX which is like combination of JS and Html, so you don't need to have script tags or html tags inside of your code, and you do not code inside of html file, you should be coding inside file that ends with js or jsx and you create as many of them as you want.首先谷歌“创建反应应用程序”，反应使用JSX，就像JS和Html的组合，所以你不需要在你的代码中有脚本标签或html标签，你不要在ZFC35FDC70D5FC69A53EZ文件内编码，你应该在以 js 或 jsx 结尾的文件中进行编码，您可以根据需要创建任意数量的文件。 It's best to have file for each bigger component, so your code is like pieces of legos and website is what you built with these legos.最好为每个更大的组件都有文件，这样你的代码就像乐高积木一样，而网站就是你用这些乐高积木构建的。
