SessionStorage 将变量布尔值设置为 NaN 或 null (Javascript)

Question

当我在会话存储中设置一个项目（然后刷新页面），然后将一个变量设置为该项目时，由于某种原因它将该变量设置为 NaN 或 null，我该如何停止呢？（保存文件）

    var myVar = false;

function save() {
    sessionStorage.setItem("myVar", myVar)
}

function load(){
    myVar = sessionStorage.getItem("myVar")
    myVar = parseInt(myVar) //is supposed to set myVar as the stored variable called "myVar"
    //if i do console.log() and print the variable value, it either shows up as NaN or Null
    //if i didnt do 'parseInt' then the value will be 'false', but the value is in strings???
    //(when value is in strings, it wont work in an "if (myVar == false){}")
}

Answer 1

存储在 sessionStorage 中的值是字符串。

使用它来转换为布尔值：

myVar = sessionStorage.getItem("myVar") === "true";
