使用Script组件在Next.js中向头部插入脚本
<p>我想在我的Next.js应用程序的每个页面的Head部分中插入来自名为Zoho的应用程序的跟踪代码。我使用的是一个名为_document.tsx的文件，它正常工作。对于一个倾斜的脚本，Next.js建议使用Next.js Script组件（https://nextjs.org/docs/messages/no-script-tags-in-head-component）。我按照说明将脚本插入到括号中，但它被忽略了，没有错误消息。我可以在_document.tsx文件的Head部分输入这段代码吗？是否最好将其拆分为一个单独的组件？</p>
<p>任何建议都将有所帮助</p>
<pre class="brush:php;toolbar:false;">import Document, {

Head,
Main,
NextScript,
DocumentContext,
DocumentInitialProps,
} from "next/document";
import Script from "next/script";
class MyDocument extends Document {
static async getInitialProps(
ctx: DocumentContext
): Promise<DocumentInitialProps> {
const initialProps = await Document.getInitialProps(ctx);
return { ...initialProps };
}
render() {
return (

我重新阅读了之前的帖子Next 11 and adding Script tags not working. No scripts are rendered enter link description here，意识到你不能把
<Script>组件放在Head标签中。此外，它不应该在_document.tsx中，而应该在_app.tsx中（除非你使用beforeInteractive，参见上面的链接）。因为我还想包含Google Analytics脚本，所以我创建了一个名为TrackingCode的组件作为单独的js文件。
import Script from "next/script"; function TrackingCode() { return ( <> {/* Global site tag (gtag.js) - Google Analytics */} <Script src="https://www.googletagmanager.com/gtag/js?id=G-GOOGLEID" /> <Script id="google-analytics" strategy="afterInteractive"> {` window.dataLayer = window.dataLayer || []; function gtag(){window.dataLayer.push(arguments);} gtag('js', new Date()); gtag('config', 'G-GOOGLEID'); `} </Script> {/* for Zoho Marketing Automation */} <Script id="zoho-ma"> {`var w = window; var p = w.location.protocol; if (p.indexOf("http") < 0) { p = "http" + ":"; } var d = document; var f = d.getElementsByTagName("script")[0], s = d.createElement("script"); s.type = "text/javascript"; s.async = false; if (s.readyState) { s.onreadystatechange = function () { if (s.readyState == "loaded" || s.readyState == "complete") { s.onreadystatechange = null; try { loadwaprops( "mycode", "mycode", "mycode", "mycode", "0.0" ); } catch (e) {} } }; } else { s.onload = function () { try { loadwaprops( "mycode", "mycode", "mycode", "mycode", "0.0" ); } catch (e) {} }; } s.src = p + "//ma.zoho.com/hub/js/WebsiteAutomation.js"; f.parentNode.insertBefore(s, f);`} </Script> {/* end Zoho marketing automation */} </> ); } export default TrackingCode;我的_app.tsx文件如下：
import "../assets/scss/material-kit.scss"; import "../node_modules/bootstrap/scss/bootstrap.scss"; import "../styles/globals.scss"; import { useEffect } from "react"; import type { ReactElement, ReactNode } from "react"; import type { NextPage } from "next"; import type { AppProps } from "next/app"; import TrackingCode from "../components/tracking-code"; import store from "../app/store"; export type NextPageWithLayout = NextPage & { getLayout?: (page: ReactElement) => ReactNode; }; type AppPropsWithLayout = AppProps & { Component: NextPageWithLayout; }; export default function MyApp({ Component, pageProps }: AppPropsWithLayout) { const getLayout = Component.getLayout ?? ((page) => page); useEffect(() => { typeof document !== undefined ? require("../node_modules/bootstrap/dist/js/bootstrap") : null; }, []); return getLayout( <> <TrackingCode /> <Component {...pageProps} /> </> ); }
