javascript - 在javascript中使用一种我似乎无法在任何地方找到的localStorage

Question

所以我有一个保存和加载功能，我大概一年前就在使用它，但在这个庄园里找不到保存和加载的例子。我的问题是我没有将这些数字保存和加载为整数，但我不记得或找不到我需要做什么才能将这些数字保存/加载为整数。很抱歉提出这样一个微不足道的问题，但这始终是一个很好的去处。

   function saveGame() {
            localStorage["ClickMiner.savedBefore"] = savedBefore;
            localStorage["ClickMiner.manaRefilCost"] = manaRefilCost;
            localStorage["ClickMiner.rocks"] = rocks;
            localStorage["ClickMiner.miningXp"] = miningXp;
            localStorage["ClickMiner.miningLevel"] = miningLevel;
            localStorage["ClickMiner.pickaxes"] = pickaxes;
            localStorage["ClickMiner.pebbleGrowers"] = pebbleGrowers;
            //localStorage["ClickMiner.rockTier"] = rockTier;
            localStorage["ClickMiner.rockTierCost"] = rockTierCost;
            localStorage["ClickMiner.bankedRocks"] = bankedRocks;
            updateTextBox("Game Saved");
            return true;
    } 

     function loadGame() {
            savedBefore = (localStorage["ClickMiner.savedBefore"]);
            manaRefilCost = (localStorage["ClickMiner.manaRefilCost"]);
            rocks  = (localStorage["ClickMiner.rocks"]);
            miningXp = (localStorage["ClickMiner.miningXp"]);
            miningLevel = (localStorage["ClickMiner.miningLevel"]);
            pickaxes = (localStorage["ClickMiner.pickaxes"]);
            pebbleGrowers = (localStorage["ClickMiner.pebbleGrowers"]);
            //rockTier = (localStorage["ClickMiner.rockTier"]);
            rockTierCost = (localStorage["ClickMiner.rockTierCost"]);
            bankedRocks = (localStorage["ClickMiner.bankedRocks"]);
            updateTextBox("Game Loaded");
            return true;
    } 

     function newGame() {
        savedBefore = 1;
        localStorage["ClickMiner.savedBefore"] = savedBefore;
        localStorage["ClickMiner.manaRefilCost"] = manaRefilCost;
        localStorage["ClickMiner.rocks"] = rocks;
        localStorage["ClickMiner.miningXp"] = miningXp;
        localStorage["ClickMiner.miningLevel"] = miningLevel;
        localStorage["ClickMiner.pickaxes"] = pickaxes;
        localStorage["ClickMiner.pebbleGrowers"] = pebbleGrowers;
        //localStorage["ClickMiner.rockTier"] = rockTier;
        localStorage["ClickMiner.rockTierCost"] = rockTierCost;
        localStorage["ClickMiner.bankedRocks"] = bankedRocks;
        location.reload();
        updateTextBox("New Game Started.");
        return true;
    } 

Answer 1

Localstorage 仅适用于字符串。

parseInt(variable)

应该做的工作
