How to Pass Data Between HTML Pages Securely with Modern Techniques

Passing Data Between HTML Pages Using Modern Techniques

The traditional approach of passing data via query parameters is convenient but visible to users. To enhance data privacy and facilitate seamless cross-page communication, consider leveraging the capabilities of HTML5.

Utilizing HTML5 Storage Objects

HTML5 introduces two storage objects, sessionStorage and localStorage, that provide a secure and efficient mechanism for managing data within a browser. sessionStorage persists data within a particular browsing session, while localStorage retains it permanently.

Code Snippets:

To store data temporarily using sessionStorage:

<code class="js">sessionStorage.setItem('label', 'value');
sessionStorage.getItem('label');</code>

To store data permanently using localStorage:

<code class="js">localStorage.setItem('label', 'value');
localStorage.getItem('label');</code>

Advantages:

Using HTML5 storage objects offers several benefits:

• Data Security: Data is stored locally and not exposed in the URL.
• Cross-Page Accessibility: Data can be accessed from any page within the same origin.
• Persistence: localStorage preserves data even after a browser reload.
• Scalability: Storage objects can accommodate large amounts of data.

Conclusion:

By employing HTML5 storage objects, developers can send and receive data between HTML pages securely and efficiently. This method eliminates the drawbacks of traditional query parameters, enhancing the user experience and bolstering data protection.
