How To Run Jquery In Chrome Console

HTML documents popular JavaScript library that makes it easy to work with HTML documents, handle events, create animations, and perform various other tasks on the web. In this blog post, we will explore how to run jQuery in the Chrome Developer Console.

Step 1: Open the Chrome Developer Console

To open the Chrome Developer Console, you can either:

  • Right-click on any web page, and select Inspect from the context menu.
  • Press Ctrl + Shift + J (Windows/Linux) or Cmd + Opt + J (Mac).

Once the console is open, click on the Console tab if it’s not already selected.

Step 2: Check if jQuery is already loaded on the page

Before running any jQuery code, it’s good practice to check if jQuery is already loaded on the page. To do this, type the following command into the console and press Enter:

typeof jQuery

If jQuery is already loaded, the console will return “function”. If jQuery is not loaded, it will return “undefined”.

Step 3: Load jQuery in the console (if not already loaded)

If jQuery is not already loaded on the page, you can load it in the console by running the following code:

    var script = document.createElement('script');
    script.src = "";

This code creates a new script element, sets its src attribute to the jQuery CDN, and appends it to the page’s head element. After running this code, you should see the message “undefined” in the console, indicating that jQuery has been loaded.

Step 4: Run jQuery code in the console

Now that jQuery is loaded, you can run jQuery commands directly in the console. For example, to hide all paragraphs on a page, you can run the following command:


To show all hidden paragraphs, run:


You can also chain multiple jQuery commands together. For example, to change the background color of all paragraphs to red and then slide them up, run:

$('p').css('background-color', 'red').slideUp();


In this blog post, we learned how to run jQuery in the Chrome Developer Console. By loading jQuery directly in the console, you can test and debug jQuery code quickly and easily, without having to save and refresh your web page. Happy coding!
