Font Awesome is a really useful tool for adding icons to your website. It also comes with animated icons which can be used to show when your form is waiting for a response. In the example below, I have created a basic Twitter Bootstrap page. The page has a form. When the form is submitted, there is a delay in its response. During the delay, I use jQuery to show a Font Awesome animated icon.
First the Twitter Bootstrap page with the differences in red:

JS and CSS fall back using PHP
There are several solutions to JS and CSS out there on the web. I've tried quite a few, but I find that if I take my network connection out, they don't work. They don't fall back. Recently, maxcdn.bootstrapcdn.com went down causing websites, including my own, to suffer from a lack of bootstrap. Even though I'd put in some fall back code.
This prompted me to write the following code. Now I know I'll be criticised for using PHP as the solution, but if you've suffered as I have, you may consider this worth a try. Below is the PHP class followed by the HTML page which makes use of the class with the calls highlighted in red. In this case I'm calling Twitter Bootstrap.

Dynamically activate navigation items in Bootstrap using my jQuery plugin
My challenge was to write a piece of jQuery which:
First the HTML. Notice, that I have not set any navigation item as active. The plugin will do this. The plugin call is in red.

Next the jQuery plugin named 'activatenav.plugin.js'.
First calculate the end of the path. If there is no name, it must be the home page, so set that as active.
I also check if the current page is from the drop down menu. If so, set both the drop down heading and the corresponding navigation item as 'active'.
(function($)
{
$.fn.extend(
{
activatenav:function(options)
{
var pname = window.location.pathname;
var pArr = pname.split('/');
var defaults =
{
toplevel:'',
dropdown:''
};
options = $.extend(defaults, options);
if(options.toplevel)
{
handled = $(this).handleTopLevel(options.toplevel, pArr[pArr.length-1]);
if(handled == false)
{
$(this).handleDropdown(options.dropdown, pArr[pArr.length-1]);
}
}
}
});
$.fn.handleTopLevel = function(str, pth)
{
var hd = false;
if(!pth)
{
$(str).first().parent().addClass('active');
}
else
{
$(str).each(function()
{
if($(this).attr('href') == pth)
{
$(this).parent().addClass('active');
hd = true;
}
});
}
return hd;
};
$.fn.handleDropdown = function(str, pth)
{
$(str).each(function()
{
if($(this).attr('href') == pth)
{
$(this).parent().addClass('active');
$(this).closest('li.dropdown').addClass('active');
}
});
};
})(jQuery);
- Takes note of the page path.
- Compares it with the Bootstrap navigation.
- Makes the navigation element 'active' to remind the users where they are in relation to the site.
First the HTML. Notice, that I have not set any navigation item as active. The plugin will do this. The plugin call is in red.

Extend your footer to the browser window using jQuery
Some pages only have a small amount of content and aesthetic reasons you'l like your page footer to extend all the way to the edge of the browser window. There are ways to do this using CSS, but this method also requires to to code your pages differently too. I like to keep the code of my pages straight forward. HTML should not be altered for styling purposes.
So I wrote a jQuery plugin to do this. See below.
(function($)
{
$.fn.extend(
{
footersizeset: function(options)
{
var defaults =
{
footertag:'footer',
ofh:100
};
options = $.extend(defaults, options);
var windowheight = $(this).height();
var footer = $(options.footertag);
var footerposition = footer.position();
var footerheight = options.ofh;
var footerbottom = footerheight + footerposition.top;
if(windowheight > footerbottom)
{
difference = windowheight - footerbottom;
footer.height(footerheight + difference);
}
}
});
})(jQuery);
Here's how to call the plugin. First you find what the height of the footer would be before the footer is reset. This is done outside all other jQuery calls so that this value doesn't keep getting reset as the browser window size changes.
Then, I make 2 calls to the plugin, once for the page load and subsequently for browser window changes.
var originalfooterheight = $('footer').height();
(function()
{
$(window).footersizeset(
{
footertag:'footer',
ofh:originalfooterheight
});
$(window).resize(function()
{
$(this).footersizeset(
{
footertag:'footer',
ofh:originalfooterheight
});
});
})();
Hope that makes sense.

footer.height(footerheight + difference);

Using PHP to get YouTube Channel feed into Twitter Bootstrap thumbnails
I've been working on a Twitter Bootstrap site. The client created a YouTube channel and wanted the feed coming into the site. Some of the videos added are uploaded by the users, some come from subscriptions. There is a nice class called thumbnail in Twitter Bootstrap for such things, so I thought I'd use that. I'm happiest getting external data using PHP. Here's how it's done.
Replace the word 'Google' with the name of your channel.
<?php
$url = 'https://gdata.youtube.com/feeds/api/videos?q=Google&max-re%20sults=5&v=2&alt=jsonc&orderby=published';
$json = file_get_contents($url);
$data = json_decode($json);
$items = $data->data->items;
foreach($items as $child)
{
echo '<a href="'.$child->player->default.'" class="thumbnail">';
echo '<h4>'.$child->title.'</h4>';
echo '<img src="'.$child->thumbnail->sqDefault.'" alt="'.$child->title.'" />';
echo '<footer>'.date("jS F Y",strtotime($child->updated)).'</footer>';
echo '</a>';
}
?>

echo '<h4>'.$child->title.'</h4>';
echo '<img src="'.$child->thumbnail->sqDefault.'" alt="'.$child->title.'" />';
echo '<footer>'.date("jS F Y",strtotime($child->updated)).'</footer>';
echo '</a>';
}
?>

jQuery file upload in Twitter Bootstrap modal
For a recent project, I have needed to add a file upload form to a modal. This has required me to perform the upload through jQuery in order to avoid the page reloading when the form is submitted.
To accomplish this I have used the jQuery form plugin at http://malsup.com/jquery/form/.
Here's the code with the important bits highlighted in red.
