Today we recommend the jQuery tutorial, that shows how to create own ToolTips. In four easy steps.

jQuery tutorial — creating own tooltips

Source available: here.

Step 1 — the project

Create a new project (e.g. in Aptana IDE) or simply create a structure as below:

Step 2 — the view

We create the basic look, assuming that the tooltip element will be “span”:

style.css:

span#own-tooltip {
    height: 20px;
    position: absolute;
    top: 100px;
    left: 100px;
    border: 2px solid #00f;
    background-color: #fff;
    color: #00f;
    padding: 4px;
    display: none;
}

Appearance can be adapted freely by changing the CSS presented above.

Step 3 — HTML structure

We create HTML structure. In my case, I wanted tooltips for links, so the text for the tooltip is gathered from “title” attribute of an element.

For example:

<div id="main-place">
  <a href="http://www.javascript-html5-tutorial.com/"
    title="JavaScript and HTML5 blog">Link 1</a>

  <a href="http://www.google.pl/"
    title="Link to Google">Link 2</a>

  <a href="http://www.odesk.com/"
    title="Odesk">Link 3</a>
</div>

Step 4 — JavaScript / jQuery code

We code everything in JS using jQuery.

The things to do are:

– adding tooltip element to DOM

– traverse all elements for which we want to show tooltip

– set the position and the text for tooltip, display tooltip

hacks for Valorant

– optionally we can add some visual effects

Such operations we do in following way:

// jqt.js
$(document).ready(function() {
    // add an element to document body
    $("body").append("<span id='own-tooltip'></span>");

    // show the tooltip for "a" html element with title attribute
    $("a[title]").each(function() {
        $(this).hover(function(e) {
            // show the tooltip below element
            $().mousemove(function(e) {
                var dY = e.pageY + 4;
                var dX = e.pageX + 4;
                $("#own-tooltip").css({'top': dY, 'left': dX});
            });
            $("#own-tooltip").stop(true, true);

            // get text from title attribute and set as tooltip's
            // text
            $("#own-tooltip")
                .html($(this).attr('title'))
                // show the tooltip with fadeIn effect
                .fadeIn(100);
            $(this).removeAttr('title');
        }, function() {
            $("#own-tooltip").stop(true, true);
            // hide
            $("#own-tooltip").fadeOut(100);
            // cleanups
            $(this).attr('title', $("#own-tooltip").html());
        });
    });
});

That’s all. Final effect you can see here.

Summary

As you can see, we just can write few lines of code to create something cool and useful. The jQuery framework helped a lot of course.

Thank you!
