在 React Helmet/ Gatsby 中插入自定义脚本

Question

I have this custom script that from a third party I am trying to embed into React Helmet我有这个来自第三方的自定义脚本，我试图将它嵌入到 React Helmet 中

Usually the scripts are given only as a src url.通常脚本仅作为 src url 给出。 If I am given the code below, what is the best practice to embed the embed the script with React Helmet如果给我下面的代码，使用 React Helmet 嵌入脚本的最佳实践是什么

    <script>
document.getElementsByTagName('head')[0].appendChild(function(s){
    var d=document,m2g=d.createElement('script'),l=function(){Mobi2Go.load(s.container,s.ready);},jq=window.jQuery&&+window.jQuery.fn.jquery.replace(/^(\d+).*$/,'$1')===1&&+window.jQuery.fn.jquery.replace(/^\d+\.(\d+).*$/,'$1')>=7,qs=window.location.search.substring(1),re='=(.*?)(?:;|$)',c=d.cookie.match('MOBI2GO_SESSIONID'+re),w=window.innerWidth;
    m2g.src='https://www.mobi2go.com/store/embed/1990-v8oL.js?'+qs+(jq?'&no_jquery':'')+(c?'&s='+c[1]:'')+'&device_width='+w;
    if(m2g.onload!==undefined)m2g.onload=l;else m2g.onreadystatechange=function(){if(m2g.readyState!=='loaded'&&m2g.readyState!=='complete')return;m2g.onreadystatechange=null;l();}
    window.Mobi2Go_est = +(new Date);
    return m2g;
}({
    container: 'Mobi2Go-Storefront', // Replace with ID  of the element to inject UI into
    ready: function() {} // Callback to fire when app is ready
}));
</script>

There is obviously errors if I include all of that in the React Helmet Not sure what is the best practice to make it work.如果我将所有这些都包含在 React Helmet 中，显然会出现错误。不确定使其工作的最佳实践是什么。

I have also tried placing it in the html.js file in gatsby我也试过把它放在 gatsby 的 html.js 文件中

 import React from 'react';
import PropTypes from 'prop-types';

export default function HTML(props) {
  return (
    <html {...props.htmlAttributes}>
      <head>
        <meta charSet="utf-8" />
        <meta httpEquiv="x-ua-compatible" content="ie=edge" />
        <meta
          name="viewport"
          content="width=device-width, initial-scale=1, shrink-to-fit=no"
        />
        {props.headComponents}
      </head>
      <body {...props.bodyAttributes}>
        {props.preBodyComponents}
        <div
          key={`body`}
          id="___gatsby"
          dangerouslySetInnerHTML={{ __html: props.body }}
        />
        {props.postBodyComponents}
      </body>
      <script
        dangerouslySetInnerHTML={{
          __html: `
          document.getElementsByTagName('head')[0].appendChild(function(s){
            var d=document,m2g=d.createElement('script'),l=function(){Mobi2Go.load(s.container,s.ready);},jq=window.jQuery&&+window.jQuery.fn.jquery.replace(/^(\d+).*$/,'$1')===1&&+window.jQuery.fn.jquery.replace(/^\d+\.(\d+).*$/,'$1')>=7,qs=window.location.search.substring(1),re='=(.*?)(?:;|$)',c=d.cookie.match('MOBI2GO_SESSIONID'+re),w=window.innerWidth;
            m2g.src='https://www.mobi2go.com/store/embed/1990-v8oL.js?'+qs+(jq?'&no_jquery':'')+(c?'&s='+c[1]:'')+'&device_width='+w;
            if(m2g.onload!==undefined)m2g.onload=l;else m2g.onreadystatechange=function(){if(m2g.readyState!=='loaded'&&m2g.readyState!=='complete')return;m2g.onreadystatechange=null;l();}
            window.Mobi2Go_est = +(new Date);
            return m2g;
        }({
            container: 'Mobi2Go-Storefront', // Replace with ID  of the element to inject UI into
            ready: function() {} // Callback to fire when app is ready
        })););
        `,
        }}
      />
    </html>
  );
}

HTML.propTypes = {
  htmlAttributes: PropTypes.object,
  headComponents: PropTypes.array,
  bodyAttributes: PropTypes.object,
  preBodyComponents: PropTypes.array,
  body: PropTypes.string,
  postBodyComponents: PropTypes.array,
};

Answer 1

It should work using react-helmet , there are examples of it in the README .它应该使用react-helmet工作，在README中有它的例子。

You might be missing type="text/javascript" in your script tag:您的script标签中可能缺少type="text/javascript" ：

<script type="text/javascript">
  // your script goes here
</script>

Al alternative option if this doesn't work for you is to customize Gatsby's html.js .如果这对您不起作用，另一种选择是自定义 Gatsby 的 html.js 。

Answer 2

Use the script tag inside the helmet tag.使用头盔标签内的脚本标签。 Most important your script should me inside the curly braces最重要的是你的脚本应该在花括号内

 <Helmet> <script> {`alert( 'Hello, world;' );`} </script> </Helmet>
