Utility belt of awesome, small javascript snippets that I use very often.

Some simple stuff that I use very often in projects.

console.js

// Avoid `console` errors in browsers that lack a console.
(function() {
	var method;
	var noop = function () {};
	var methods = [
		'assert', 'clear', 'count', 'debug', 'dir', 'dirxml', 'error',
		'exception', 'group', 'groupCollapsed', 'groupEnd', 'info', 'log',
		'markTimeline', 'profile', 'profileEnd', 'table', 'time', 'timeEnd',
		'timeStamp', 'trace', 'warn'
	];
	var length = methods.length;
	var console = (window.console = window.console || {});

	while (length--) {
		method = methods[length];

		// Only stub undefined methods.
		if (!console[method]) {
			console[method] = noop;
		}
	}
}());

debounce.js

// Returns a function, that, as long as it continues to be invoked, will not
// be triggered. The function will be called after it stops being called for
// N milliseconds. If `immediate` is passed, trigger the function on the
// leading edge, instead of the trailing.
function debounce(func, wait, immediate) {
	var timeout;
	return function() {
		var context = this, args = arguments;
		var later = function() {
			timeout = null;
			if (!immediate) func.apply(context, args);
		};
		var callNow = immediate && !timeout;
		clearTimeout(timeout);
		timeout = setTimeout(later, wait);
		if (callNow) func.apply(context, args);
	};
};

imagesLoaded.js

// Images loaded
(function(c,q){var m="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///ywAAAAAAQABAAACAUwAOw==";c.fn.imagesLoaded=function(f){function n(){var b=c(j),a=c(h);d&&(h.length?d.reject(e,b,a):d.resolve(e));c.isFunction(f)&&f.call(g,e,b,a)}function p(b){k(b.target,"error"===b.type)}function k(b,a){b.src===m||-1!==c.inArray(b,l)||(l.push(b),a?h.push(b):j.push(b),c.data(b,"imagesLoaded",{isBroken:a,src:b.src}),r&&d.notifyWith(c(b),[a,e,c(j),c(h)]),e.length===l.length&&(setTimeout(n),e.unbind(".imagesLoaded",
p)))}var g=this,d=c.isFunction(c.Deferred)?c.Deferred():0,r=c.isFunction(d.notify),e=g.find("img").add(g.filter("img")),l=[],j=[],h=[];c.isPlainObject(f)&&c.each(f,function(b,a){if("callback"===b)f=a;else if(d)d[b](a)});e.length?e.bind("load.imagesLoaded error.imagesLoaded",p).each(function(b,a){var d=a.src,e=c.data(a,"imagesLoaded");if(e&&e.src===d)k(a,e.isBroken);else if(a.complete&&a.naturalWidth!==q)k(a,0===a.naturalWidth||0===a.naturalHeight);else if(a.readyState||a.complete)a.src=m,a.src=d}):
n();return d?d.promise(g):g}})(jQuery);

// Images loaded, but also does background images
var images = $('img, .bg-img');
$.each(images, function(){
	var el = $(this),
	image = el.css('background-image').replace(/"/g, '').replace(/url\(|\)$/ig, '');
	if(image && image !== '' && image !== 'none')
		images = images.add($('<img>').attr('src', image));
	if(el.is('img'))
		images = images.add(el);    
});
images.imagesLoaded();

indexof.js

/* IndexOf polyfill */
if (!Array.prototype.indexOf) {
	Array.prototype.indexOf = function (searchElement, fromIndex) {
		if ( this === undefined || this === null ) {
		throw new TypeError( '"this" is null or not defined' );
		}

		var length = this.length >>> 0; // Hack to convert object.length to a UInt32

		fromIndex = +fromIndex || 0;

		fromIndex = 0;
		}

			fromIndex = 0;
		}
		}

		for (;fromIndex < length; fromIndex++) {
		if (this[fromIndex] === searchElement) {
			return fromIndex;
		}
		}

		return -1;
	};
}

pad.js

// Pad numbers
function pad(input) { if (input < 10) {return '0' + input;} return input; }

placeholder.js

// Placeholder polyfill
if (!Modernizr.input.placeholder) {
	$('input[placeholder]:not(.ph), textarea[placeholder]:not(.ph)').each(function () {
		var place = $(this).attr('placeholder');

		$(this).attr('value', place);

		});

		$(this).addClass('ph');
	});
}
