First version of my Form-Preview plugin for jQuery

form-preview.js

$(function () {
	var view     = $('#preview'),
	    elements = $('.preview-form form').find('select, input, textarea');
    
	function preview (specific) {
		if (view.hasClass('off')) {
			return;
		}
	
		if ( !specific ) {
			specific = elements;
		}
	
		specific.each(function () {
			var self = $(this);
			var value = self.val();
		
			var element = view.find('[data-preview=' + self.attr('name') + ']');
		
			var attribute = element.attr('data-attr'),
				pattern   = element.attr('data-pattern');
		
			if (pattern) {
				value = pattern.replace('%s', value);
			}
		
			if (!attribute) {
				element.html(value);
			}
			else {
				element.attr(attribute, value);
			}
		});
	}

	view.find('a').attr('target', '_blank');

	elements.on('input', function () {
		var self = $(this);
	
		preview(self);
	});

	preview();
});
