在网页中如何右键弹出菜单？

• 回答：

  function MouseEvent(dX, dY, lType) {
      if(lType == 3)
      {
          // 鼠标右键按下
          var filter = mxOcx.NewResbuf();
  
          // 5020 = RTDXF0,只选择直线实体，设置过滤条件
  
          //filter.AddStringEx("LINE",5020);
  
          var ent = mxOcx.FindEntAtPoint(dX, dY, filter);
  
          var sPopMenu;
          if(ent != null)
          {
              mxOcx.ClearCurrentSelect();
              mxOcx.AddCurrentSelect(ent.ObjectID,true,true);
  
              sPopMenu = mxOcx.GetOcxAppPath() + "\\MxPopMenuEnt.mnu"
          }
          else
          {
              sPopMenu = mxOcx.GetOcxAppPath() + "\\MxPopMenu.mnu"
          }
  
  
          mxOcx.TrackPopupMenu(dX, dY, sPopMenu);
          // 设置1，表示鼠标事件，不再往下传递.
          mxOcx.SetEventRet(1);
      }
  }
