jQuery 1.4 Animation Techniques - Index of

Managing Animations
Passing an empty array to the queue() method will also
clear the queue.
Useful properties of the jQuery object
The jQuery object contains a couple of properties that we can set which can be useful when
creating animations. The jQuery (or $) object contains an fx property, which itself contains
two properties related to animations which we can manipulate.
This fx object is not to be confused with the fx queues that are created by default for any
element that has more than one animation method called on it in a chain. These individual
fx queues do not contain the same properties that the jQuery fx property contains.
Globally disabling animations
One property of fx that we can set is the off property. This property contains a Boolean
that is set to false by default, but which we can set to true to globally disable all
animations on a page. The property is set using the following syntax:
jQuery.fx.off = true;
That's all we do need to do. If this is set at any point in our script, all elements that have
animation methods attached to them will be set to their final state, as if the animation
had already completed.
Changing the default frame rate
The other property of jQuery's fx that we can set is the interval property. This property
accepts an integer and specifies the number of milliseconds between each frame of the
animation. By default, it is set to 13, so an animation will have a frame-rate of about 76
frames per second.
To set this property, we just supply a different integer:
jQuery.fx.interval = 28
Setting the property to 28 like this would make the animation run at about 35 frames per
second, making animations run almost half as smoothly.
Note that animations will still run over the same duration of time (whether that is the default
400 milliseconds, or another value set with the duration argument of an animation method)
regardless of what this property is set to. However, an interval value that is lower, and
therefore has a higher number of frames per second, will make animations appear smoother.
