I read this solution, but is not clear how to implement in my case
let button = document.querySelector('button');
let options = document.querySelector("#btn-start");
chrome.storage.local.get(['button'], function(status) {
console.log('Value currently is ' + status.button);
console.log(typeof(status.button))
if ( status.button === 'Stop') {
setButtonStop();
}
});
button.addEventListener("click", changeButtonStatus);
function changeButtonStatus(){
let buttonStatus = document.querySelector("button").innerText;
let status = '';
if ( buttonStatus === 'Start')
status = setButtonStop();
if ( buttonStatus === 'Stop')
status = setButtonStart();
chrome.storage.local.set({button: status }, function() {
console.log('Value is set to ' + [status]);
});
}
function setButtonStop () {
options.setAttribute("id", "btn-stop");
button.innerText = "Stop";
return button.innerText;
}
function setButtonStart () {
options.setAttribute("id", "btn-start");
button.innerText = "Start";
