How to Share Data Between HTML Pages Securely with HTML5?

Sharing Data Between HTML Pages

When the need arises to communicate data between HTML pages, querying parameters come to mind. However, this method leaves data exposed in the URL. Fortunately, HTML5 provides alternative solutions for secure and seamless data sharing using JavaScript or jQuery.

To address the concern of data exposure, HTML5 introduces storage objects like sessionStorage and localStorage. These objects allow developers to store key-value pairs for temporary (session-based) or permanent (cross-session) usage.

Using SessionStorage

sessionStorage.setItem('label', 'value');

This stores a value associated with a key during the current session.

To retrieve the stored value:

sessionStorage.getItem('label');

Using LocalStorage

localStorage.setItem('label', 'value');

This stores a value associated with a key permanently, even after a browser restart.

To retrieve the stored value:

localStorage.getItem('label');

By utilizing HTML5 storage objects, you can securely store form data between multiple pages, ensuring that data remains accessible even after reloading the browser.
