var objState
//------------鼠标经过时-----------
 function OnFoucsMouseOver( obj,fontColor,backColor )
 {
  if ( obj.rowIndex > 0 )
  {
   obj.style.color = fontColor;
   obj.style.backgroundColor = backColor;
  }
 }
//-----------鼠标离开时-----------
 function OnFoucsMouseOut( obj,fontColor,backColor )
 {
  if ( obj.rowIndex > 0 )
  {
   if ( obj != objState )
   {
    obj.style.color = fontColor;
    obj.style.backgroundColor = backColor;
   }
  }
 }
//-----------鼠标单击时-----------
 function OnFoucsClick( obj,fontColor,backColor )
 {
  if ( obj.rowIndex > 0 )
  {
   if ( objState != null )
   {
    objState.style.color = "";
    objState.style.backgroundColor = "";
   }
   obj.style.color = fontColor;
   obj.style.backgroundColor = backColor;
 
   objState = obj;
  }
 }
//-----------鼠标双击时-----------
 function OnFoucsDbClick( obj,fontColor,backColor,openUrl )
 {
  //参数openUrl为要开的新窗口的地址
  if ( obj.rowIndex > 0 )
  {
   if ( objState != null )
   {
    objState.style.color = "";
    objState.style.backgroundColor = "";
   }

   obj.style.backgroundColor = backColor;
 
   objState = obj;
 
   window.open( openUrl );
  }
 }

后台数据梆定例子：
==========================================
  private void dgList_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)
   {
    //
    if ( e.Item.ItemIndex != -1 )
    {
     e.Item.Attributes.Add( "onMouseOver","OnFoucsMouseOver(this,'#FFFFFF','#000000');" );
     e.Item.Attributes.Add( "onMouseOut","OnFoucsMouseOut(this,'#000000','#FFFFFF');" );
     e.Item.Attributes.Add( "onClick","OnFoucsClick( this,'#FFFFFF','#000000' );" );
     e.Item.Attributes.Add( "onDblClick","OnFoucsDbClick( this,'#FFFFFF','#000000','about:bank' );" );
    }
   }
