Setup: Download and install the Fluid Infusion library

1. Download a copy of the Fluid Infusion component library from:
   • http://fluidproject.org/products/fluid-infusion/download-infusion/
     You only really need the "Minified deployment package," but if you want to actually look at the code, you should download the "Source package."
2. Unpack the zip file you just downloaded, and place the resulting folder somewhere convenient for your development purposes.
   The folder will have the release number in its name (e.g. infusion-1.4/). The rest of this tutorial will use infusion-1.4 in its examples, but if you downloaded a different version, you'll have to adjust.

Step 1: Prepare your markup

We'll start with an HTML file called pop-up-progress.html. This page contains one thing, a big button that says,

<div id="main">
    <p>
        <button id="showButton">Do something...</button>
    </p>
</div>

Now we need to add the markup that describes the Progress component.

The most basic Progress component is made up of a bar and an indicator. You can include other markup in your Progress but you must include these two elements. (Although the bar does not have to be visible.)

Our Tutorial example contains a few other elements.

The HTML looks like this:

<div class="container" id="main">
    <p>
        <button id="showButton">Do something...</button>
    </p>
    <div class="flc-progress progress-pop-up">
        <h3>Current Progress</h3>
        <div class="flc-progress-bar progress-bar">
            <div class="flc-progress-indicator progress-indicator">
            </div>
        </div>
        <p class="flc-progress-label progress-label">
            0% Complete
        </p>
    </div>
</div>

In the code above, the indicator element is contained within the progress bar element. While this is typical, it is not required. The indicator and the progress bar can be marked up quite independently of each other. The only requirement is that there be both an indicator element and a bar element as the width of the progress bar determines the final, 100%, width for the indicator.

Step 2: Write the script

For this tutorial, we'll assume that you're putting your Progress initialization and control code into a file named progress-sample.js. In your own integration you may want to add your Progress code to an existing Javascript file in your application.

In your file, write a function to initialize the Progress component:

var myProgress; // you'll need to refer to this later

jQuery(document).ready(function () {
    myProgress = fluid.progress("#main");

});

The code above is so simple because in this example we chose to use the defaults already defined for the Progress component. All we had to do is tell Progress where to find all it's parts – inside a container with an id of main. Progress knows to look for a displayElement with a class of flc-progress, and a progressBar with a class of flc-progress-bar, etc.

Let's make a small change to the default options. Let's change the default speed for updating the Progress indicator element. We'll make it run a bit slower and a bit smoother than the default. Like so:

jQuery(document).ready(function () {
    myProgress = fluid.progress("#main", {
        speed: 1000 // the default is 200, quite fast
    });
});

Finally we need to wire up our "do something" button to call our anIllusionOfProgress function:

$("#showButton").click(function () {
    anIllusionOfProgress(myProgress, 0, 20);
});

A full description of the public methods of Progress can be found in the Progress API.

Step 3: Add the scripts to your HTML

You'll need to add your script and the Fluid library to your HTML file. In the header of the file, link to the Javascript files with <script> tags:

<script type="text/javascript" src="infusion-1./InfusionAll.js"></script>
<script type="text/javascript" src="js/progress-sample.js"></script>

NOTE that the InfusionAll.js file is minified - all of the whitespace has been removed, so it isn't really human-readable. If you're using the source distribution and you want to be able to debug the code, you'll want to include each of the required files individually. This would look like this:

<script type="text/javascript" src="lib/jquery/core/js/jquery.js"></script>
<script type="text/javascript" src="lib/jquery/ui/js/ui.core.js"></script>
<script type="text/javascript" src="lib/jquery/plugins/bgiframe/js/jquery.bgiframe.js"></script>  <!-- New in v1.3 -->
<script type="text/javascript" src="framework/core/js/Fluid.js"></script>
<script type="text/javascript" src="components/progress/js/Progress.js"></script>

But all of these individual files are not necessary to make it work - the InfusionAll.js file has everything you need.

Step 4: Apply styles

Your progress won't look or behave like a Progress Bar without some styling. The Progress component does not come with default CSS for styling since you can build so many different kinds of progress bars with it.

For this example we're using a set of styles expressed in the progress-sample.css file from the Pop-up Progress standalone demo.

A few things to note about how we've styled the Progress elements in this example:

#main {
    position: relative; /* ensures the enclosed elements are positioned relative to the container */
}

.progress-bar {
    text-align: left;   /* pins the indicator to the left in IE */
}

.progress-indicator {
    height: 16px;       /* the height of the interior object will determine the 
                           height of it's parent, in this case */
}
