To use jQuery in a web page, insert a <script> tag and set the tag’s src (Source) property to a jQuery file.
You can set the Source property to a Google-hosted jQuery file, or you can host your own copy of jQuery.
jQuery has evolved over several versions. In general you should use the most current version; however, you may need to use an earlier version, for example if you wish to use a plugin which requires an earlier version and is incompatible with the current version.
Google-hosted jQuery file
You can use Google-hosted jQuery for free. Copy the code below and paste into your web page.
For other versions of jQuery, and other Google-hosted libraries, see Google Libraries API Developer’s Guide.
Host your own copy of the jQuery file
- Click “Download” button
- File name will be jquery-something.js — name varies with version of file
- Save jQuery file in folder of your choice
- Insert <script> tag into web page, set src to jQuery file
- jQuery is now available
