How Can I Store JavaScript Variables Across Pages?

Storing JavaScript Variables Across Pages

JavaScript variables are only available within the page in which they are declared. However, there are ways to persist these variables across different pages.

Utilizing Window.name as JavaScript Session

One technique is to use the window.name property to store the variable. This is known as JavaScript session. The syntax is as follows:

window.name = "someValue";

You can then retrieve the value from another page using:

var retrievedValue = window.name;

However, this technique only works within the same window or tab. If you navigate to a different window or tab, the value stored in window.name will be lost.

Other Persistent Storage Options

Other options for persistent storage include:

• HTML5 Web Storage (localStorage and sessionStorage): These provide key-value storage that persists across page reloads.
• IndexedDB: A database API that allows for structured data storage.
• Third-party cookies: While cookies have privacy concerns, they can be used for persistent storage. However, they may be blocked by browsers.
