浏览器窗口/标签关闭时如何删除localStorage项目？ [英] How to delete a localStorage item when the browser window/tab is closed?

问题描述

我的案例：带有键+值的localStorage应该在浏览器关闭时删除，而不是单个标签。

My Case: localStorage with key + value that should be deleted when browser is closed and not single tab.

请查看我的代码是否合适且可以是什么改进：

Please see my code if its proper and what can be improved:

//create localStorage key + value if not exist
if(localStorage){
   localStorage.myPageDataArr={"name"=>"Dan","lastname"=>"Bonny"}; 
}

//when browser closed - psedocode
$(window).unload(function(){
  localStorage.myPageDataArr=undefined;
});

推荐答案

应该这样做而不是删除操作符：

should be done like that and not with delete operator:

localStorage.removeItem(key);
