How to store a value of variable in javascript for new tab opened in browser

This function works fine as well as I'm getting currentUrl here:

currentUrl

var currentUrl;

function onFileSelected(event)
var selectedFile = event.target.files[0];
var reader = new FileReader();

var result = document.getElementById("result");

reader.onload = function(event)
currentUrl = event.target.result;
result.innerHTML = event.target.result;
;

reader.readAsText(selectedFile);
return currentUrl;



The problem is that this is launching a new Chrome window and the value of my currentUrl variable is lost:

currentUrl

function launchChromeAndRunLighthouse(currentUrl, opts, config = null)
const cmd = `lighthouse $currentUrl --chrome-flags="--headless"`;

exec(cmd, (error, stdout, stderr) =>
if (error !== null)
console.log(`exec error: $error`, stderr);

);



I have an HTML file which takes a text file as input and the text file contains multiple URLs. I want to read the text file and grab that URL in my currentUrl variable. Currently I'm able to read the text file and also able to grab the current URL in the currentURL variable but when I run the launchLighthouse function it's launching a new Chrome window and thus my variable is lost and it shows me undefined variable.

currentUrl

currentURL

launchLighthouse
