I checked log file, and it's have no error.
any one can give me some help?
Did you solve your problem? I ran into a similar issue.
All questions about vSphere Web Clients get much faster responses if you post them in the vSphere Web Client forum :-)
Regarding this issue, 2 things:
1) Either the Virgo log will show a specific error regarding the tranformation of the Script plugin into a Web client plugin.
2) There is a known bug in 5.1 whereas Script plugins may not be displayed by the Web client if you are also using other "normal" plugins registered on the same vCenter. This is fixed in 5.1 Update 1 (not sure if this is out yet) and in 5.5 beta.
