Pluralink is an amazing javascript plugin to arrange multiple links in your text. Here is how it works. Suppose you have to include 3 links in a text. What you usually do is that you list it one after the other in a single line which gives a feeling of repetition. For example, if you want to link to google, yahoo and bing in a single line, you will write as “the three top search engines google, yahoo, bing contribute …”.

But with Pluralink you can show all your links as a drop down list from which the user can choose any of those. It gives a nicer look as well. You can download either the pure pluralink version or the wordpress plugin version for free.

A few months ago, James Padolsey introduced a cool greyscale technique for non-IE browsers. His technique inspired SohTanaka to come up with a workaround with a similar effect.

Greyscale Hover Effect with CSS & jQuery relies on CSS Sprites and a few lines of jQuery, but requires a bit of preparation before it can be implemented. It is not recommended for large scale projects and probably best for displaying portfolio pieces.

You have a small area. You mouse over it. An area pops up giving you a zoomed in closer look. AnythingZoomer is a jQuery plugin that does it.

It’s flexible in many ways, in that the “small”, “large”, and “zoom” areas are all pretty easy to customize via CSS. It’s inflexible in other ways, in that it doesn’t “automatically” work by cloning content or anything like that (which is arguably more flexible), and the HTML structure is fairly rigid.

Today we’re going to break the mold of the traditional tooltip. This tutorial will demonstrate how to build tooltips that are powered by jQuery, with information pulled from a JSON array. Here’s a look at the final result that we’ll be looking to make:

Our page will have two links. When a user hovers over a link, it will trigger the top banner to change its background image and text based on the entry in a JSON array. See the Demo

We’ll be using a pack of background images in later steps. You can grab those here.

Build the Page Structure

New File: I have called my HTML file ‘json-tooltip.htm” for this tutorial

Our example’s HTML is pretty self explanatory. We’re just blocking out a banner to contain the tooltip information, and then placing all of the normal content below.

Pay special attention to what’s going on with link anchors with a class of “tooltip” though. This is the class that will designate which links are tooltips. Also, you’ll notice that the “rel” attribute contains a number. This is the number we’ll use to associate a specific tooltip to an anchor link. This will become clear in a few steps. (more…)

(mb)Tooltip is a beautiful tooltip for your webpage in jQuery. Simply by placing a “title” attribute with your content as value, and then you can replace the ugly default tooltip with this smart and nice one. You can also disable and enable (mb)Tooltip at anytime.

Captify jQuery Plugin displays simple, pretty image captions that appear on rollover. Captions can be locked “always-on”, or set to fade in on rollover. Also, captions can slide in from the top or the bottom.

Captify was inspired by ImageCaptions, another jQuery plugin for displaying captions like these. unlike ImageCaptions at the moment, Captify is easy to use, small/simple, and completely ready for use in production environments. Captify has been tested on Firefox, Chrome, Safari, and Internet Explorer.

A New jQuery plugin: imgPreview allows your users to preview an image before clicking on it and, out of necessity, will preload the image so when a user does click through to it there is no waiting time.

The image preview shows up in a tooltip-like box appearing alongside the user’s cursor when hovering over a link. The plugin is entirely unobtrusive; it does not require any hooks to target specific links (no non-semantic classes); it will automatically detect the anchors that are linking to images and will only apply the preview effect to them.

Additionally, it allows for quite a high level of customisation with Callback functions as well. You can also specify a thumbnail prefix for images. So, it won’t take too long time to load larger images.

It began as a simple Drag and Drop / Constrained Mover example, and with the help of a couple #dojo community members took shape into a fully featured demo showing the power of the Dojo Toolkit.

Peter Higgins has created Dojo Zoomer. It is divided into 3 panels. By hovering over the image on the left panel, right panel dynamically displays the cropped portion of the image, so that you can focus explicitly on the portion of the main image that interests you. You can see a list of thumbnails at the bottom panel which is enhanced with a paging/switching mechanism with dojo.fx and some onclick events as well.

CSS tooltips are very popular in modern web design and contrary to popular belief it is really easy to create them, especially with one of the all so popular javascript frameworks. In that case, you have to use at least a plugin. However, Kriesi.at has shared us an article of “Create simple tooltips with CSS and jQuery” which teaches us how to get some basic tooltips with only about 10 lines of CSS and jQuery Code.
