How to .replace an encodedURLcomponent on javascript bookmarklet

To replace an encoded URL component using a JavaScript bookmarklet, you can follow these steps:

Step 1: Create a JavaScript bookmarklet A bookmarklet is a bookmark stored in a web browser that contains JavaScript code instead of a URL. To create a bookmarklet, follow these steps:

1. Right-click on your browser's bookmarks bar and select "Add Page" or "Add Bookmark."
2. Give the bookmarklet a name, such as "Replace Encoded URL Component."
3. In the URL or Location field, enter the following JavaScript code:

javascript:(function() {
  // Your code goes here
})();

Step 2: Replace the encoded URL component Inside the bookmarklet's JavaScript code, you can use the .replace() function to replace the encoded URL component. Here's an example code snippet:

javascript:(function() {
  var encodedURL = "https%3A%2F%2Fexample.com%2Fpage%3Fparam%3Dvalue";
  var decodedURL = decodeURIComponent(encodedURL);
  var replacedURL = decodedURL.replace("example", "newexample");

  // Open the replaced URL in a new tab
  window.open(replacedURL, "_blank");
})();

In the above code, we first decode the encoded URL using decodeURIComponent(). Then, we use the .replace() function to replace the desired part of the URL. Finally, we open the replaced URL in a new tab using window.open().

Please note that this is just a basic example, and you can modify the code according to your specific requirements.

Remember to encode the bookmarklet's JavaScript code before saving it as a bookmark. You can use online tools like "Bookmarklet Crunchinator" or "Bookmarkleter" to encode the JavaScript code.
