How To Check If Html Sessionstorage Is Not Empty?

G'day guys, I'm trying to figure out the best way to check for empty storageSession in HTML5. I noticed that some browser returns null and some return just empty space if you clear

Solution 1:

That should work; the problem is that you have null in quotes.

Also, sessionStorage.length will give you the number of values stored.

Solution 2:

But this is how you check for "empty" session storage

   if (sessionStorage.length == 0) {

Solution 3:

Use this to check if there is item is session storage called "name"

if (sessionStorage['name']) {
    console.log("There is 'name' in session storage ")
}

Solution 4:

You can also try

if($window.sessionStorage.value === undefined) {}

Solution 5:

i checked this way

   $(document).ready(function () {
       if (window.sessionStorage) {
           if (sessionStorage.getItem("x-mas") === null) {
               if (getCountryCode() == 'de') {
                   $('#xmasModal').modal();
                   sessionStorage.setItem("x-mas", "1")
               }
           }
       }
   });

   functiongetCountryCode() {
       var url = window.location.pathname;
       var segments = url.split('/');
       var countrycode = segments[1];
       return countrycode;
   }
