If you're a Greasemonkey enthusiast looking to fine-tune your Chrome experience, you may have encountered the need to restrict your scripts to specific webpages. This targeted approach can enhance your browsing experience by tailoring the script's functionality to particular sites. In this guide, we'll walk you through the steps to restrict your Chrome Greasemonkey scripts to a single webpage or just certain webpages.
Firstly, before diving into the specifics of restricting your Greasemonkey scripts, it's crucial to understand the script metadata. In your script header, you can define the "@match" metadata to specify the URL pattern where your script should run. This metadata serves as the foundation for targeting specific webpages.
To restrict a Greasemonkey script to a single webpage, you can utilize the "document.URL" property within your script code. By comparing the current URL to the desired webpage, you can conditionally execute the script's logic only when it matches the designated URL. This approach ensures that your script is exclusively applied to the intended webpage.
// @match https://example.com/target-page
if (document.URL === 'https://example.com/target-page') {
// Your script logic for the target webpage
}If you're aiming to restrict your script to multiple webpages that share a common pattern, you can leverage regular expressions for more flexibility. The "test" method allows you to check if the URL matches the defined pattern, enabling your script to adapt to various URLs within the specified criteria.
// @match https://example.com/*
const urlPattern = /https://example.com/w+/;
if (urlPattern.test(document.URL)) {
// Your script logic for pages matching the pattern
}However, if you want to restrict your Greasemonkey script to multiple specific webpages, you can create an array of URLs and verify if the current URL exists within this array. This method grants you the ability to target a predefined list of webpages with a single script.
// @match https://example.com/page1
// @match https://example.com/page2
const allowedURLs = ['https://example.com/page1', 'https://example.com/page2'];
if (allowedURLs.includes(document.URL)) {
// Your script logic for the specified webpages
}By implementing these techniques, you can effectively restrict your Chrome Greasemonkey scripts to a single webpage or just certain webpages. Whether you're customizing your browsing experience or enhancing site-specific functionalities, mastering the art of targeted script execution empowers you to optimize your Greasemonkey usage. Experiment with these approaches and tailor your scripts to suit your browsing needs with precision.
