重新加載頁面后不保存變量

Question

當我運行下面的代碼時，如果登錄成功，它通常會在 testUses 中添加一個數字。 但是，當我重新加載時，您仍然可以訪問 home.html 並且變量 testUses 仍然保持為 0，這意味着由於某種原因，它沒有改變。 我應該把 testUses 放在 function 之外嗎？ 請回答修復或提示以更改此設置。

Answer 1

您可以將testUses存儲在localStorage中。

let testUses = +localStorage.getItem('testUses') || 0;
// update value:
testUses++;
localStorage.setItem('testUses', testUses);
