How to reload page without resetting tampermonkey script?

Question

I'm using javascript to create some automation action in a website. I know that chrome console would be reset when we hit the refresh button, so I'm trying to manage it by Tampermonkey so the script can run individually from the chrome console.

But my issue still there, tampermonkey userscript still reset when page is reloaded. Can you help me with those problem? Many thanks! p/s I'm an amateur in this coding subject so it is grateful if you guys can give me a hand :)

A part of my script is look like this:

var $balance = $("#balance"), $statusBar = $(".progress #banner"); function getStatus() { var a = $statusBar.text(); if (hasSubString(a, "Rolling in")) return "waiting"; if (hasSubString(a, "***ROLLING***")) return "rolling"; if (hasSubString(a, "rolled")) { var b = parseInt(a.split("rolled")[1]); return lastRollColor = getColor(b), "rolled" } return "unknown" } function getBalance() { return parseInt($balance.text()) }

The TamperMonkey script will indeed also reset when the page is reloaded. However, you can save the state between reloads so that your script can continue where it left off.

You can use the GM_getValue and GM_setValue functions to store data in some Tampermonkey data store, so that it is available the next time the script runs. Note that you need to use the @grant header to use those functions.

For example, the following script keeps the value of counter between reloads:

// ==UserScript== // @name HttpBin reload // @namespace http://tampermonkey.net/ // @version 0.1 // @description Reload something a couple of times // @author Sjoerd // @match https://httpbin.org/get // @grant GM_setValue // @grant GM_getValue // ==/UserScript== (function() { 'use strict'; var i = GM_getValue('counter', 0); GM_setValue('counter', i + 1); if (i < 5) { location.reload(); } })();

This seems to persist across pages. E.g. say you have a script running on fakesite.it* and you set the counter on fakesite.it/food and visit fakesite.it/eat, no reloads seem to occur. Or, if you want to revisit fakesite.it/food again later, no reloads occur.
FYI, GM_getValue and GM_setValue are deprecated. It's now GM.getValue and GM.setValue
Is there a reason to prefer this over localStorage or sessionStorage?

You could try adding whatever it is you are trying to save to the localStorage of the page and whenever you need whatever you just saved, you can just get it from the localStorage.

Here are 2 commands to do so:

localStorage.setItem(keyName, keyValue);
localStorage.getItem(keyName);
