Using Javascript to navigate from a specific anchor point to a different webpage

Question

Using Javascript to navigate from a specific anchor point to a different webpage

Currently, I have a series of links that utilize #anchors to direct users to different sections within the same webpage. However, I am considering transitioning to a setup where each link corresponds to its own separate webpage. My goal is to ensure that the existing links continue to work by implementing redirects.

Original link format:

/all_products#A
/all_products#B
/all_products#C

New link format:

/products/A
/products/B
/products/C

While I am aware that the server does not receive the anchor name in the request, there may be a way to achieve this using JavaScript.

Is it feasible to automatically redirect from /all_products#A to /products/A through the use of JavaScript?

I believe utilizing jQuery for this purpose would be appropriate, as it is already integrated into the website.

In this updated answer, I have included some essential best practices for both retrieving the hash from the URL and performing a redirect.

// Wrapped in a closure for added security.
(function () {
    var anchorMap = {
        "A": "/products/A",
        "B": "/products/B",
        "C": "/products/C"
    }
    /*
    * Recommended method for extracting hashes:
    * https://stackoverflow.com/a/10076097/151365
    */
    var hash = window.location.hash.substring(1);
    if (hash) {
        /*
        * Best practice for JavaScript redirects: 
        * https://stackoverflow.com/a/506004/151365
        */
        window.location.replace(anchorMap[hash]);
    }
})();

Place this script near the top of your HTML <head> section to ensure it runs before other page resources load:

<script>
function checkURL() {
    var old_path = '/all_products';
    if (window.location.pathname != old_path) {
        // Not on an old-style URL
        return false;
    }
    // Some browsers include the hash character in the anchor, remove it
    var product = window.location.hash.replace(/^#(.*)/, '$1');
    // Redirect to the new-style URL
    var new_path = '/products';
    window.location = new_path + '/' + product;
}
checkURL();
</script>

This script verifies the current page URL and redirects if it matches the old path.

The code utilizes the window.location object, which contains various parts of the URL separated by components.

Adapting this script for broader use is encouraged for further customization.

Here is a potential solution for your issue:

Let's break down the code:
- The variable urlSplit is created to store the result of splitting the current URL by the "#" symbol.
- If there is a value in urlSplit at index 1 (meaning if there is a hash fragment in the URL), then the page is redirected to "http://www.example.org" followed by the hash fragment.
- If there is no hash fragment present in the URL, then the page is simply redirected to "http://www.example.org".

This code snippet is designed to handle URL redirection based on the presence of a hash fragment. Make sure to test it thoroughly before implementing it on your site.

Using the power of jquery, you have two options to update links:

$('a').each(function() {
  this.href = this.href.replace(/all_products#/, 'products/');
});

You can also handle link clicks and perform a redirect:

$('a').click(function() {
  window.location = this.href.replace(/all_products#/, 'products/');
  return false;
});
