How to Find the jQuery Version on a Webpage

This method works in most modern web browsers and is the preferred approach for quick checks. Here's how to do it:

• console.log(jQuery().jquery);
  

Checking the Source Code (Less common):

This method involves looking at the actual source code of the webpage. It's less convenient than using the console but can be helpful if you don't have access to the developer tools.

• Look for the jQuery Script: Search for the line of code that includes the jQuery library. It might look something like this:

  <script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
  

Key Points:

• Both methods assume jQuery is already loaded on the webpage. If it's not loaded, the console code will result in an error, and you won't see any reference to jQuery in the source code.
• The first method using the console is generally faster and easier, especially if you're just trying to identify the version quickly.

console.log(jQuery().jquery);

This code snippet utilizes the console.log() function to display the output of the expression jQuery().jquery within the browser's developer console.

• jQuery(): This part calls the jQuery function without any arguments, which typically initiates jQuery on the page and returns a jQuery object.
• .jquery: This accesses a property of the jQuery object that holds the version number as a string.

Running the Code:

1. Open the webpage where you want to check the jQuery version.
2. Right-click anywhere on the page and select "Inspect" or "Inspect Element".
3. Locate the "Console" tab within the developer tools window.
4. Paste the code console.log(jQuery().jquery); into the console and press Enter.
5. If jQuery is loaded correctly, the version number will be displayed in the console output.

1. Browser Extensions (Less reliable):

• Some browser extensions claim to identify libraries loaded on a webpage, including jQuery and its version. However, these extensions might not always be accurate or reliable.
• Proceed with caution and verify the information with the other methods if you choose this route.

1. Network Tab in Developer Tools (For advanced users):

• This method involves looking at the network requests made by the webpage. It's more technical and might not be suitable for beginners.
• Open the developer tools and navigate to the "Network" tab.
• Reload the webpage.
• Look for requests related to jQuery libraries (usually named something like "jquery.min.js").
• If you find a relevant request, you can often see the version number either in the request details or the file name itself.

Remember:

• The console method remains the most recommended approach due to its simplicity and reliability.
• Source code inspection is a good backup option if the console isn't accessible.
• Browser extensions and network tab inspection should be used cautiously and might require more technical knowledge.
