Extract all URLs from a web page

Here is a quick JavaScript snippet to extract all URLs from a webpage, using Developer Tools. No Browser Extension is required!

const results = []; var urls = document.getElementsByTagName('a'); for (urlIndex in urls) { const url = urls[urlIndex] const externalLink = url.host !== window.location.host if(url.href && url.href.indexOf('://')!==-1) results.push([url.href]) // url.rel } const urlLists = results.map((line)=>{ return line.map((cell)=>{ if(typeof(cell)==='boolean') return cell ? 'TRUE': 'FALSE' if(!cell) return '' let value = cell.replace(/[\f\n\v]*\n\s*/g, "\n").replace(/[\t\f ]+/g, ' '); value = value.replace(/\t/g, ' ').trim(); return `"${value}"` }).join('\t') }).join("\n"); console.log(urlLists)// display url list copy(urlLists) // copy to clipboard
