How to delete a localStorage item when the browser window/tab is closed?

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

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;

});

There are five methods to choose from:

setItem(): Add key and value to localStorage
getItem(): Retrieve a value by the key from localStorage
removeItem(): Remove an item by key from localStorage
clear(): Clear all localStorage
key(): Passed a number to retrieve nth key of a localStorage
You can use clear(), this method when invoked clears the entire storage of all records for that domain. It does not receive any parameters.



window.localStorage.clear();
