t:ACCELERATE Attribute | accelerate Property?deprecated) | DHTML中文手册 |
sets or retrieves a value that applies an acceleration to the element's local timeline.
dhtml语法
xml <ELEMENT t:ACCELERATE = fRate... > Scripting object.accelerate [ = fRate ]
DHTML可能的值
fRate Floating-point number that specifies a value between 0 and 1 representing the portion of the local timeline over which the acceleration is applied. The local timeline refers to the timeline associated with a particular HTML element (such as a div or span), rather than the global timeline associated with the entire document.
0 Default. Acceleration is not applied to the element's timeline. The property is read/write. The property has a default value of 0.
Remarks
If the t:repeat or t:repeatdur attribute is set on an element, the acceleration occurs each time the element repeats.
the t:accelerate attribute is especially well suited to animation content and behaviors. setting this attribute to a nonzero value does not affect the duration of the timeline, but it could change the effective play speed of the local timeline. the sum of the values for the t:accelerate and t:decelerate attributes must not exceed 1. this property is also commonly known as "ease-in" in some systems.
