How Can I Detect Hash Anchors in URLs Using JavaScript?

Detecting Hash Anchors in URLs with JavaScript

When working with anchor links, it becomes essential to determine if a hash (#) anchor link is present within a given URL. Here's a straightforward JavaScript approach to accomplishing this:

Solution: Using Window.location.hash

Explanation:

The window.location.hash property provides easy access to the fragment identifier (# and the subsequent characters) in the current URL. By utilizing this property, we can create a simple test to detect the presence of a hash in the following manner:

JavaScript Code:

if (window.location.hash) {
    // Fragment exists (hash is present)
} else {
    // Fragment doesn't exist (no hash)
}

Example Usage:

To use this solution, you can implement it in your jQuery/JavaScript code:

$(function() {
    if (window.location.hash) {
        // Execute code when a hash is present
        console.log("Hash detected:", window.location.hash);
        // ...

    } else {
        // Execute code when no hash is present
        console.log("No hash found.");
        // ...
    }
});

Advantages of this Solution:

• Simplicity: The code is straightforward and easy to understand.
• Cross-Browser Compatibility: It works consistently across major browsers.
• No external dependencies: It doesn't require any additional JavaScript libraries or plugins.
