version number(id) is attached to html control id in javascript

[Google Code Exporter]

This is a random case. i cant understand how it generates the IDs but when i 
write the javascript code and use the control id it take something like this.

Original id="mPlayer_playerPoster"
Generated id=?v=16010101053000"mPlayer_playerPoster"

this doesnt happen everytime but when i write the code for javascript so many 
times i found this issue. has anyone faced this one? is there any workaround 
for this?
