function onEnter(evt,frm,box_id)

// this function gives intelligence to the enter key. it decides which button code to execute.

// Fixed two problems with Biblion Catalog Search Box in this code on 5/5/09. 
// 	First Problem: If user pressed enter and did not enter any query in the Search Box, a new library landing page window would appear. 
//                     I put in a check to make sure the search query length is greater than 0.
//      Second Problem: (From Ticket #104188) User enters search query, presses enter. The search result window opens (as expected). However
//                     if user then goes from that window back to library landing page and enters a new query and presses enter, nothing happens.
//                     The problem was the browser already thinks the search result window is open because the id for the window was called
//                     myWindow. I put a random number generator in to create different window names so the browser now thinks it's opening a new
//                     window (which it is).  5/5/09 JRF
