If you're a developer who often works with jQuery, you might occasionally find yourself needing to figure out the version of jQuery included in a particular web page. Fortunately, inspecting the jQuery object is a simple way to get this information quickly. In this article, we'll guide you through the steps to easily determine the jQuery version in use.
When you're on a webpage where jQuery is loaded, simply open up the browser's developer console. You can usually do this by right-clicking on the page and selecting "Inspect" or pressing F12 on your keyboard. Once you have the console open, you'll need to navigate to the Console tab.
In the console, simply type `jQuery.fn.jquery` and press Enter. This command will return the version of jQuery being used on the page. The number that appears represents the version of jQuery that has been loaded. It's usually displayed in a format like `3.6.0`, indicating the major, minor, and patch versions of jQuery.
If you're working with a page that doesn't use the `$` alias for jQuery, you can still access the version information. You'll need to find the jQuery object by searching for any element on the page that has jQuery properties and methods attached to it. Once you've identified the jQuery object, you can then use the same command `jQuery.fn.jquery` in the console to retrieve the version.
In some cases, websites may have jQuery loaded in no-conflict mode, which means the `$` alias is not used. If this is the case, you'll need to use `jQuery` instead of `$` when accessing the jQuery object to get the version information.
It's important to note that this method works only when jQuery is already loaded on the page. If jQuery is not present, running `jQuery.fn.jquery` will return an error since the jQuery object does not exist.
Inspecting the jQuery object to get the version is a handy trick for developers who need to quickly determine the jQuery version used on a webpage. By following these simple steps in the browser console, you can easily retrieve the version information and ensure compatibility with the features and functions of the specific jQuery version being used.
Next time you're working on a project and need to verify the jQuery version in use, remember this straightforward method to inspect the jQuery object and obtain the version details promptly.
