SwellJS – another big fish in the sea

Since the last post, we’ve received a huge number of requests and questions about drag&dropping files onto your beloved browser.

The mechanism behind is quite simple:  the Ajax library, the DOM element wrapper and the Asset component are assuring most of the work (handling the upload and the callback process), the DDM detects the dragged files,  then your browser is doing the rest, defining the interaction between your desktop and the file input (nicely styled of course).

By now, two browsers are playing well with the demo (Safari 4, Chrome 2+)  while others degrades gracefully.

Here’s the code :

Swell.Core.Event.add('upload', 'change', function() {
    $('loader').show();
    $('foorm').xhr(function() {
        var currentEl = $('upload').current();
        $('filelist').show();
        for (var i = 0, len = currentEl.files.length; i < len; i++) {
            $('filelist').appendHTML(currentEl.files.item(i).fileName + '
');
        }
        var imgs = this.responseText.split('|');
        new Swell.Core.Asset().load('img', imgs, function(img) {
            $('loader').hide();
            $(img).appendTo('image-container');
        });
    });
});
