怎么删除key以 / 开头的session

Question

Answer 1

window.sessionStorage获取整个 sessionStorage
遍历 for(let key in sessionStorageObj)
判断 if(sessionStorageObj.indexOf("/") !== -1) , //包含/ ,
则移除 sessionStorage.removeItem（key）

Answer 2

window.sessionStorage.setItem('/a/b/c/ddd', true)
window.sessionStorage.removeItem('/a/b/c/ddd')

Answer 3

//刷新的时候删除缓存的数据
window.addEventListener('beforeunload', e => {

let sessionStorageObj = window.sessionStorage
for(let key in sessionStorageObj){
    if(key.startsWith("/")){
      console.log("123")
      sessionStorage.removeItem(key)
    }
}

});
