JS to grab a linkedin memberID from a profile

get-linkedin-id.js

// paste this in the chrome console and call findMemberID() when on a profile page
// need to be logged in

function decodeHtml(html) {
    var txt = document.createElement("textarea");
    txt.innerHTML = html;
    return txt.value;
}

function httpGet(){
    var xmlHttp = new XMLHttpRequest();
    xmlHttp.open( "GET", location.href, false );
    xmlHttp.send( null );
    return xmlHttp.responseText;
}
const gregex = /li:member:[0-9]+/g;

function findMemberId(){
	// we can't simply grab from the DOM due to the values getting clobbered :(
	// so we grab the profile HTML as a string and regex the member ID out
	var html = decodeHtml(httpGet());
	results= [];
	while ((m = gregex.exec(html)) !== null) {
		// This is necessary to avoid infinite loops with zero-width matches
		if (m.index === gregex.lastIndex) {
			gregex.lastIndex++;
		}
		
		results.push(m);
	}
	return results[results.length-1][0].split(':')[2]
