给服务器控件添加快捷键

做的这个功能是现在项目的四个可伸缩的栏目对应的快捷键，“49”，“50”，“51”，“52”分别对应键盘键ctrl+1，ctrl+2，ctrl+3，ctrl+4，可以通过ASCII对照表查到

 1<script language="javascript">
 2        function   document.onkeydown()   
 3          {   
 4              if   (event.keyCode   == 49&&event.ctrlKey)   
 5              {   
 6                var   btn   =   document.getElementById("ctl00_cphCommonBodyColumn_pnlConsignBasicExpand");  
 7              
 8                  if   (btn   !=   event.srcElement)   
 9                  {   
10                      btn.click();   
11                      return   false;   
12                  }   
13              }   
14              if   (event.keyCode   == 50&&event.ctrlKey)   
15              {   
16                var   btn   =   document.getElementById("ctl00_cphCommonBodyColumn_pnlCargonExpand");
