Html Country List with flags [closed]

问题

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.

Note from the future: jQuery UI autocomplete now supports custom rendering by default, see http://api.jqueryui.com/autocomplete/#method-_renderItem.

It's pretty easy. Things you need:

jQuery UI auto-complete
UI auto-complete html extension
A list of country names/codes
A CSS sprite with all flags

Remember, Google is your friend. Blend the ingredients well, carefully whisk some javascript in, and it's done - in 7 lines of code:

var countries = [["Argentina", "ar"], ...];

var countryNames = countries.map(function(country){
  return {
      label: '<div class="flag '+country[1].toLowerCase()+'">'+country[0]+'</div>',
      value: country[0]
  }
});

$('#country').autocomplete({
  source: countryNames,
  html: true
});

Here's this code in action

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');

回答3:

As mentioned by commenters, a CSS sprite is the proper solution here. Fortunately, there are many CSS sprites of flags freely available. This one looks pretty good.

We will have to tweak the dropdown code to accomodate that pre-made CSS sprite. I've gone ahead and done that for you. Here's a live demo.

The CSS changes I made were Q&D hacks; you'll probably want to spend some time polishing them. I removed all of the flag-specific stuff from languageswitcher.css since we're using flag16.css.

Also, if the country code doesn't exist in the CSS sprite, the flag shown will default to the

African Union's flag since it is the first image in the sprite. In the demo, several of the countries in my example list don't have a sprite image. Watch out for that.

Here's a file with the list of countries and links to their flags (some of the links might not be working though but most of them are) Excel File

回答5:

You can also use flags from http://www.famfamfam.com/lab/icons/flags/ and simply use CSS for positioning the appropriate flag.

----EDITED----

If i need to show flag of my country then i would do mapping from CSS like

<span class='np'></span>

.np {
background: url(./flags_preview_large.png) -172px -397px no-repeat;
width: 14px;
height: 20px;
}
