Video: Adding the tip info

Now in order for us to be able to have content show up in the tooltip, we need to put some data into the HTML file that we can actually pull from. So in the HTML file, we are going to start by adding some of that data into the anchor link that's inside of the article, now not inside of the aside, but inside of the first paragraph, inside of the article. And the linked text says text-based tooltip. So this anchor link here, right now we are pointing to a pound sign which is just a self link. Now inside of here we want to add some additional attributes. So we are going to start by adding some data attributes, which is fully compliant with HTML5 and is the recommended way for putting data onto an HTML element that's not seen by the public, but gives us the ability to access that through JavaScript.

Tooltips can greatly improve the usability of your web site by providing direction and cues to visitors. In this course, Chris Converse shows how to convert text or graphics into a mouse-sensitive tooltip. The tutorials demonstrate how to write the necessary HTML and activate the tooltip with jQuery, as well as add positioning and effects.

Topics include:
  • Saving web graphics from Photoshop
  • Creating the tooltip container
  • Adding the jQuery $(document).ready() and mouse events
  • Detecting and setting HTML-based tooltips
  • Attaching the tip container to the mouse
  • Setting the tooltip to fade in and out
  • Accounting for other CSS-positioned elements

Adding the tip info

Now in order for us to be able to have content show up in the tooltip, we need to put some data into the HTML file that we can actually pull from. So in the HTML file, we are going to start by adding some of that data into the anchor link that's inside of the article, now not inside of the aside, but inside of the first paragraph, inside of the article. And the linked text says text-based tooltip. So this anchor link here, right now we are pointing to a pound sign which is just a self link. Now inside of here we want to add some additional attributes. So we are going to start by adding some data attributes, which is fully compliant with HTML5 and is the recommended way for putting data onto an HTML element that's not seen by the public, but gives us the ability to access that through JavaScript.

So inside of the anchor tag, after the href attribute, let's hit a space and the first data item we are going to put in here is going to be data-tip-type, equals, two quotes. We are going to put in the word text. Now we are making up this value, we are going to have two different types, if you remember from the Introduction movie, a text-based tooltip and an html-based tooltip. So after that attribute, but still inside of the anchor tag, let's hit a space.

We are going to type data-tip-source, equals, two quotes, and in here we are going to put the actual text that's going to show up as the tooltip text. So we'll type "This is text for a tooltip." And the last thing we are going to add to this anchor tag is going to be a class; this is how we are going to actually target these items with jQuery.

So lastly we'll add a class attribute, equals, two quotes, and the class is going to be tooltip. Then hit Save. Now we are using a class here because we want to reuse the name tooltip, any number of times on our page, and what's really advantageous about this is we can write one jQuery statement that targets tooltips, and then we are going to come in here and check to see what type of tooltip it is, and then what the actual content is. So now that we have defined an HTML element as having a class of tooltip and having a data tip type, and a data tip source, next we can work on actually finding this object and then modifying the tooltip container based on the data inside of this element.
