I am looking for a way to select and display a list of countries, preferably with flags. Any suggestions?
I started of by trying this jQuery plugin http://www.graphicpush.com/website-language-dropdown-with-jquery, but as the list of countries I have is quite large it turned out that the performance was really bad (too many http requests to images). Also the list is bulky when it is larger than 50 elements.
Just wanted to suggest a (imho) smarter way of doing the flags sprite.
The idea is to save the flags in a grid according to the country iso2 code.
1st letter -> vertical position
2nd letter -> horizontal position
Examples (for 16x11px flags + 4x4px spacing):
Austria = AT
A = 1 => vertically 1st row => y = (1-1)*(11+4) = 0
T = 20 => horizontally 20th column => x = (20-1)*(16+4) = 380
United States = US
U = 21 => vertically 21st row => y = (21-1)*(11+4) = 300
S = 19 => horizontally 19th column => x = (19-1)*(16+4) = 360
This way I can calculate the flag location with a very easy function on the client side without the need of 200+ extra style definitions.
Sample jQuery plugin:
(function($) {
// size = flag size + spacing
var default_size = {
w: 20,
h: 15
};
function calcPos(letter, size) {
return -(letter.toLowerCase().charCodeAt(0) - 97) * size;
}
$.fn.setFlagPosition = function(iso, size) {
size || (size = default_size);
return $(this).css('background-position',
[calcPos(iso[1], size.w), 'px ', calcPos(iso[0], size.h), 'px'].join(''));
};
})(jQuery);
Demo Usage:
$('.country i').setFlagPosition('es');
