jquery jQuery.fx.interval attribute syntax
Function:jQuery.fx.interval property is used to change the animation running rate in milliseconds. This property can be manipulated to adjust the number of frames per second at which the animation runs. The default value is 13 milliseconds. This property is often used to modify the number of frames per second at which the animation runs. Lowering this value can make animations run more smoothly in faster browsers, but doing so may impact performance. Since jQuery uses a global interval, in order for this property to take effect, the animation should no longer be running or all animations should be stopped first. This attribute has no effect in browsers that support the requestAnimationFrame attribute, such as Google Chrome 11.
Syntax: jQuery.fx.interval = milliseconds;
Parameters:
| Parameter | Description |
| milliseconds | Required. Specifies the animation run rate in milliseconds. The default is 13 milliseconds. |
