刷新页面时localStorage变空

Question

当我刷新页面时，

localStorage变空。

我在代码中所做的是： - 1）我已将authToken存储在localStorage中 2）我在sessionStorage中存储了isReloaded值，以检查页面是否是新打开的还是回发

如果首次打开浏览器选项卡，则在tabCount localStorage中增加浏览器选项卡计数值，如果重新加载浏览器，则不应在tabCount中添加任何值，如果我关闭所有选项卡而不注销页面，则所有localStorage都应该清除。

实现代码的目的： -

1）页面应清除localStorage值，如果所有浏览器选项卡都关闭而不注销页面。 2）页面实例应该在多个选项卡中打开

$(window).load(function () {


if(!sessionStorage.getItem('isReloaded'))
{
    //first time call

   if(localStorage.getItem('tabCount') == null || localStorage.getItem('tabCount') == undefined)
   {
       var tabCount = 1;
       localStorage.setItem('tabCount',tabCount.toString());    
   }
   else
   {
      var tabCount = parseInt(localStorage.getItem('tabCount'));
      tabCount += 1;
      localStorage.setItem('tabCount',tabCount.toString()); 
   } 


}
else
{
    // postback code here
    console.log('in postback...')
}

 sessionStorage.setItem('isReloaded',true);

});

$(window).unload(function(){

     var tabCount = parseInt(localStorage.getItem('tabCount'));
     if(tabCount > 0)
     {
        tabCount -= 1;
        if(tabCount == 0)
        {
            //RemoveLocalStorage('tabCount,authToken,userId,userName,userFullName,caseNo,consumerName, consumerFirstName, consumerLastName, consumerList, userData,timeStamp');
           localStorage.setItem('tabCount',tabCount.toString());                   
           localStorage.clear();
        }
        else
        {
          localStorage.setItem('tabCount',tabCount.toString()); 
        }                   
     }

});
