Very rarely does a developer have the ability to work with just one framework. Often a developer needs to float between MooTools and jQuery. As you can imagine, doing so can make a developer loopy due to the syntax difference. One of the small differences that gets used often is jQuery’s attr() and css() vs. MooTools’ set() and setStyle(). I’ve implemented css() and attr() into MooTools for jQuery users.

The MooTools JavaScript Code

Element.implement({
	css: function(property,value) {
		var type = $type(property);
		if(value == undefined && type != 'object') {
			return this.getStyle(property);
		}
		else {
			var pvs = property;
			if(type != 'object') { pvs = {}; pvs[property] = value; }
			return this.setStyles(pvs);
		}
	},
	attr: function(property,value) {
		var type = $type(property);
		if(value == undefined && type != 'object') {
			return this.get(property);
		}
		else {
			var pvs = property;
			if(type != 'object') { pvs = {}; pvs[property] = value; }
			return this.set(pvs);
		}
	}
});



console.log('css(width) = ' + $('subject').css('width'));

console.log('css(width,500) = ' + $('subject').css('width',500));

console.log('css(width,700) = ' + $('subject').css({width:700}));



console.log('attr(rel) = ' + $('subject').attr('rel'));

console.log('attr(rel,mootools) = ' + $('subject').attr('rel','mootools') + ' :: ' + $('subject').attr('rel'));

console.log('attr(rel,mootools ftw!) = ' + $('subject').attr({rel:'mootools ftw'}) + ' :: ' + $('subject').attr('rel')

I personally don’t prefer this syntax in MooTools but hopefully this helps someone!
