Question

我目前正在使用HTML和Javascript制作一个简单的游戏（我的第一个）。这是保存代码：

function save()
{
  var save = {
    ducks: ducks,
    ponds: ponds,
    pondCost: pondCost,
    ponds: ponds,
    vacuums: vacuums,
    vacuumCost: vacuumCost,
    vacuum: vacuum,
    llama: llama,
    llamaCost: llamaCost,
   llamas: llamas
  }
  localStorage.setItem("save",JSON.stringify(save));
};

这是加载代码：

function load()
{
  var savegame = JSON.parse(localStorage.getItem("save"));
  if (typeof savegame.ducks !== "undefined") ducks = savegame.ducks;
  if (typeof savegame.ponds !== "undefined") ponds = savegame.ponds;
  if (typeof savegame.pond !== "undefined") pond = savegame.pond;
  if (typeof savegame.pondCost !== "undefined") pondCost = savegame.pondCost;
  if (typeof savegame.vacuums !== "undefined") vacuums = savegame.vacuums;
  if (typeof savegame.vacuum !== "undefined") vacuum = savegame.vacuum;
  if (typeof savegame.vacuumCost !== "undefined") vacuumCost = savegame.vacuumcost;
  if (typeof savegame.llama !== "undefined") llama = savegame.llama;
  if (typeof savegame.llamas !== "undefined") llamas = savegame.llamas;
  if (typeof savegame.llamaCost !== "undefined") llamaCost = savegame.llamaCost;
  document.getElementById('ponds').innerHTML = ponds;
  document.getElementById('vacuums').innerHTML = vacuums;
  document.getElementById('vacuumCost').innerHTML = nextCost;
  document.getElementById('pondCost').innerHTML = nextCost;
};

我还添加了一个重置功能，但是只要我添加了这个功能并按下重置按钮，保存就不起作用了！（或加载）

function reset()
{
  localStorage.removeItem("save")
}

所有这些按钮都附在我的HTML中的按钮上。

好吧，如果没有完全调试你的代码，我在点击保存时会收到错误。第17行的保存功能正在执行：

vacuum: vacuum,

您没有名为vacuum的全局变量，但您有一个名为vacuums的变量。该错误正在停止任何进一步的处理。

在Javascript中保存和加载无效
