The version of jQuery that comes with WordPress is not the latest and greatest. In fact, it tends to be quite a bit behind the jQuery project itself.
If you don’t need the backward compatibility of the older versions, jQuery Updater will install the latest stable release on your website. Should you run into problems, deactivating the plugin will put things back the way they were.
Date Picker works in tandem with other plugins to convert a standard text input into a jQuery-powered, date-based suite of fields. Choose between a standard date picker, time picker, date ranges, and more. Plus, you can block out dates, making it suitable for use with a booking form.
Fixed-position widgets are great for keeping information in front of your site’s visitors. Items like shopping carts, navigation and banner ads will stay in view, even as a user scrolls. Q2W3 Fixed Widget for WordPress makes it easy to make any widget a “sticky” one, courtesy of jQuery.
Install the plugin, activate it, click into a widget and select the “Fixed Widget” option.
Web designers have long used Fancybox jQuery lightbox to add both utility and interactivity to images. The FancyBox for WordPress plugin makes it easy to integrate this tool into your website.
Any thumbnail linked to an image will automatically load in an attractive lightbox when clicked. In addition, you can customize the look and special effects via a back-end settings panel.
Add smooth scrolling effects in the form of handy up and down buttons. Click a button and it will scroll the current page (smoothly, of course) to the next or previous page/section. There’s also an optional “back to top” button.
This plugin adds jQuery form validation to the popular Contact Form 7. Easily validate the content of form fields including URLs, email addresses, dates, numbers and more.
jQuery Post Splitter takes the ability of WordPress to split up large posts into multiple pages and turns it into a unique slider. So, instead of having to click on pagination and manually load in subsequent pages, the plugin uses jQuery and Ajax to quickly load in new slides of content.
It’s a much smoother and more seamless way to navigate through a long multi-part post.
The standard Twitter Widget isn’t very flexible. Rotating Tweets brings a bit of jQuery to the fold by allowing your latest tweets to show one at a time in an animated rotation. You can display tweets as a widget or use a WordPress Shortcode.
Easily add tabbed content within your WordPress posts and pages using a drag and drop interface. Tabs can be created within a page, post or widget. Horizontal and vertical layouts are available. Tabs Responsive also includes support for Font Awesome icons as well.
Using a tiny, 8kb jQuery script, Equal Height Columns uses our spotlighted JS library to solve a web designer’s pet-peeve. Tell the plugin the targeted selectors and it does the rest. The plugin is also responsive, so you can have your fancy equally-tall columns on mobile devices, too.
