Copy code The code is as follows:

Try it yourself

Tip: Get the latest available version through Google CDN:

If you observe what's on the Google URL - the jQuery version (1.8.0) is specified in the URL. If you wish to use the latest version of jQuery, you can also remove a number from the end of the version string (such as 1.8 in this example) and Google will return the latest available version in the 1.8 series (1.8.0, 1.8.1, etc.), or It is also possible to leave only the first number, and Google will return the latest available version in the 1 series (from 1.1.0 to 1.10.2).
Microsoft CDN:

Tip: Using Google or Microsoft’s jQuery, there is a big advantage:

Many users have loaded jQuery from Google or Microsoft when visiting other sites. All the result is that when they visit your site, jQuery is loaded from cache, which reduces load times. At the same time, most CDNs ensure that when a user requests a file from them, a response is returned from the server closest to the user, which can also improve loading speeds.
