推荐答案

如果您打算只为用户存储它们，您可以使用 localstorage

If you're planning on just storing them for just the user you could use localstorage

有多种方法可以使用它，但这是一个非常简单的版本，应该会为您指明正确的方向.

There are a number of ways to use this, but this is a very simple version that should point you in the right direction.

正如@patick 在下面提到的 - 如果您想存储更完整的数据，您需要对数据进行 JSON.stringify，然后在您准备使用数据时进行解析.

As @patick mentions below - if you wanted to store more complete data you would need to JSON.stringify the data then parse later when you are ready to consume the data.

另请注意，所有 localstorage 都保存为字符串，因此您需要将其设为整数才能真正使用它.

Also note that all localstorage is saved as a string so you would need to make it an integer to really use it.

你可能会这样做

// set inital score
var score = parseFloat(localStorage.getItem('score'));

// if they get the answer correct
score = score + 1;

// update the score
localstorage.setItem('score',score);

// go to next question
