我正在将facebook社交插件添加到网页
当我手动添加:
<div class="fb-comments" data-href="http://website.com/z" data-width="700" data-numposts="7" data-colorscheme="light"></div>
但是,当javascript代码添加它时,它不会
任何想法?

JS SDK在初始化时会遍历您的文档,以查找要解析为社交插件的元素。如果您还想要解析稍后添加到文档中的内容,则需要调用FB.XFBML.parse()
。

太棒了@CBroe!
谢谢!它适用于 Nextjs/React 项目。
作为参考,请查看实现它的自定义钩子:
import { useEffect } from 'react';
let FB;
const useFacebook = ({ addTrack }) => {
useEffect(() => {
const facebookScript = document.createElement("script");
facebookScript.id = 'fb-sdk';
facebookScript.async = true;
facebookScript.defer = true;
facebookScript.crossOrigin = "anonymous";
facebookScript.nonce = "5JOEwLPT";
const track = addTrack ? `&appId=${process.env.NEXT_PUBLIC_FACEBOOK_ID}&autoLogAppEvents=1` : '';
facebookScript.src = `https://connect.facebook.net/pt_BR/sdk.js#xfbml=1&version=v10.0${track}`;
document.body.appendChild(facebookScript);
const startScript = document.createElement('script');
const code = `window.fbAsyncInit = function() {
FB.init({
appId : '${process.env.NEXT_PUBLIC_FACEBOOK_ID}',
autoLogAppEvents : ${addTrack},
xfbml : true,
version : 'v10.0'
});
};`;
startScript.appendChild(document.createTextNode(code));
document.body.appendChild(startScript);
if(window.FB) {
window.fbAsyncInit();
}
return () => {
document.body.removeChild(facebookScript);
document.body.removeChild(startScript);
}
}, [addTrack]);
};
export default useFacebook;
