How to Get URL Parameters Using jQuery or Plain JavaScript

Are you struggling to get URL parameters in your web application? Do you want an easy solution to extract specific parameters from a URL using either jQuery or plain JavaScript? Look no further! In this blog post, we'll explore how to detect and extract URL parameters in a simple and efficient way.

The Challenge

One of the common challenges faced by developers is handling URL parameters, especially when their size and names are unknown. To illustrate this, let's consider the following scenario:

You have a URL that looks like this: http://example.com?sent=yes

Your goal is to detect the existence of the sent parameter and check if its value is equal to "yes".

Using jQuery

If you're using jQuery in your project, you can leverage its built-in functionality to easily extract URL parameters. Here's how you can do it:

// Get URL Parameters in jQuery
function getParameter(url, parameter) {
  var urlParams = new URLSearchParams(url.search);
  return urlParams.get(parameter);
}

// Usage
var url = new URL("http://example.com?sent=yes");
var sentParam = getParameter(url, "sent");

if (sentParam === "yes") {
  // Hooray! The "sent" parameter exists and its value is "yes"
} else {
  // Oops! Something went wrong
}

In the above example, we define a getParameter function that takes the URL object and the parameter name as arguments. We then use the URLSearchParams constructor to parse the URL's search parameters. Finally, we use the get method to retrieve the value of the specified parameter.

Using Plain JavaScript

If you prefer using plain JavaScript without any libraries, fret not! You can still achieve the desired result using plain JavaScript methods. Here's how you can do it:

// Get URL Parameters in Plain JavaScript
function getParameter(url, parameter) {
  var searchParams = new URLSearchParams(url.search);
  return searchParams.get(parameter);
}

// Usage
var url = new URL("http://example.com?sent=yes");
var sentParam = getParameter(url, "sent");

if (sentParam === "yes") {
  // Hooray! The "sent" parameter exists and its value is "yes"
} else {
  // Oops! Something went wrong
}

Similar to the jQuery approach, we define a getParameter function that takes the URL object and the parameter name as arguments. We create a URLSearchParams object to parse the URL's search parameters and use the get method to retrieve the value of the specified parameter.
