The sessionStorage object is equal to the localStorage object, except that it stores the data for only one session. The data is deleted when the user closes the specific browser tab.
Below is an example of sessionStorage Object in HTML:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 | <!DOCTYPE html> <html> <head> <script> function clickCounter() { if (typeof(Storage) !== "undefined") { if (sessionStorage.clickcount) { sessionStorage.clickcount = Number(sessionStorage.clickcount)+1; } else { sessionStorage.clickcount = 1; } document.getElementById("result").innerHTML = "You have clicked the button " + sessionStorage.clickcount + " time(s) in this session."; } else { document.getElementById("result").innerHTML = "Sorry, your browser does not support web storage..."; } } </script> </head> <body> <p><button onclick="clickCounter()" type="button">Click me!</button></p> <div id="result"></div> <p>Click the button to see the counter increase.</p> <p>Close the browser tab (or window), and try again, and the counter is reset.</p> </body> </html> |
