Many of blueidea's friends see the effects of shrinking and expanding content. The only difference is a buffer effect. If you don't talk about it, you will know it after you run it.
A fixed value is required for the maximum height. There is no good solution. If you are interested, please help us solve the problem. Thank you.

Welcome to my friends who like JavaScript and Ajax + + QQ, and make common progress.
Usage
Call effect: Effect (1, 2 );
1 indicates the ID of the object to be changed.
Where 2 is: the control container ID can be obtained by using: This. parentnode. ID (parent tag ID)
Note: Do not repeat the Object ID.
