How to Maintain Data Integrity Across HTML Pages Without Query Parameters?

Maintaining Data Integrity Across HTML Pages

When navigating between HTML pages, it's often necessary to share data without compromising user security or the URL's readability. This article explores an alternative approach to sending data via query parameters, which stores it temporarily or permanently locally.

Solution: Leveraging HTML5 Storage Objects

Instead of relying on query parameters, consider utilizing HTML5 storage objects like sessionStorage and localStorage. These enable the storage of intermediate values that can be accessed across multiple HTML pages.

SessionStorage for Temporary Storage

To temporarily store data within a session, use sessionStorage:

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

LocalStorage for Permanent Storage

For more permanent storage, employ localStorage:

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

Benefits of HTML5 Storage

Using these objects offers several advantages:

• Data is securely stored locally, preventing URL exposure.
• Values can be retained even after page reloads, providing session continuity.
• It allows for easy sharing of data between multiple HTML pages, facilitating efficient data management.
