There exists two ways actually to clear the localStorage via JavaScript.
Way1 − Using the clear() method
localStorage.clear();
Way2 − Iterating over localStorage and deleting all key
for(key in localStorage){ delete localStorage[key]; }
Both ways will work.
Example
<html> <body> <p id = "storage"></p> <script> if (typeof(Storage) !== "undefined") { localStorage.setItem("product", "Tutorix"); // cleared before displaying localStorage.clear(); document.getElementById("storage").innerHTML = localStorage.getItem("product"); } else { document.getElementById("storage").innerHTML = "Sorry, no Web Storage compatibility..."; } </script> </body> </html>
