Generic function for a progress bar. Made with Zurb Foundation in mind.

progressBar.js

function progressBar(v) {
	'use strict';
	var value = parseInt(v);
	var currentBar = parseInt($('.meter')[0].style.width.replace(/[^\d]/g, ''));
	var newBar = value + currentBar;

	if (value + currentBar > 100) {
		$('.meter').css('width', '100%');
	} else if (value + currentBar < 0) {
		$('.meter').css('width', '0%');
	} else {
		$('.meter').css('width', newBar + '%');
	}
}
