I am looking for a method to extract query string parameters in JavaScript without relying on any plugins. Is there a straightforward way to achieve this using jQuery or pure JavaScript? If such a method does not exist, could you recommend a suitable plugin that can assist with this task?
A straightforward way to access query string parameters using pure JavaScript is to utilize the URL interface. You can create a new URL object and use the searchParams property to access the parameters. Here’s how you can do it:
const url = new URL(window.location.href);
const paramValue = url.searchParams.get('paramName');
This method is quite handy, especially with modern browsers, as it abstracts away the complexities of parsing query strings manually.
you can also split window.location.search string by ? and then use split('&') on the params part. iterate and split('=') each pair to get the key and value. it works in older browsers too without URL API. but it’s a bit more work.
If you’re using jQuery and would like a more seamless integration without manually parsing, though not strictly recommended for this task, it’s possible to use jQuery’s built-in functions to facilitate handling query strings by combining some of its functionalities. However, it’s generally preferable now to use native JavaScript methods, as outlined previously. jQuery used to be a lifesaver for compatibility issues, but with modern browsers supporting the URL API, manual parsing is less necessary, and reliance on libraries such as jQuery is gradually decreasing.
