推荐答案

将值存储在 localstorage 并从那里引用它。

Store the values in localstorage and reference it from there.

function first() {
    localStorage.setItem('myItem', "something you want to store");
}

function second() {
    myValue = null;
    if (localStorage.getItem('myItem')) {
        myValue = localStorage.getItem('myItem');
    }
}
