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;
});
should be done like that and not with delete operator:
localStorage.removeItem(key);
