js regular filtering and adding image prefixes in rich text

1. Filter the image prefix without '/' and turn it into a relative path. The following two regular rules are available. Personal test

// 示例，过滤图片前缀且不带'/'，变成相对路径

console.log('valueHtml', valueHtml.replace(/https?:\/\/[^\/]*(\/)*/g, ''));

console.log('valueHtml', valueHtml.replace(/\bhttps?:\/\/(.*?)\/+/ig, ''));

2. Add picture prefix 

valueHtml= result.detail.content.replace(/<img [^>]*src=['"]/g, `<img src="${你的域名}`)
