• On Chrome e.originalEvent.screenX take different values than e.originalEvent.clientX, unlike Firefox.

// Trigger
$('.volume').on('mousemove', function(e)
{
	console.log(e);
	console.log(e.pageX);
	$('.volume').trigger('mousedown', [e.pageX] );
});

// We get the value as

• Basic copy with = is just a reference, not new object

	var tmpDisable = {};
	var lastTmpDisable = {};

	lastTmpDisable = tmpDisable; // Any change made to any of these object will be on both because they're references

	// If we declare it this way a new object is created
	for(var key in tmpDisable)
	{
		lastTmpDisable[key] = tmpDisable[key]
	}

var size = Object.keys(myObj).length;
