jQuery Grid Plugin - jqGrid

When using ver 3.4, I included the following code to dynamically hide or show the page selector controls depending on whether or not there is more than 1 page:

       if(jQuery("#tblcontents").getGridParam("records") > jQuery("#tblcontents").getGridParam("rowNum")){
            jQuery("#tblcontentsPager").find("#first, #prev, input.selbox, #sp_1, #sp_2, #next, #last").show();
          }else{
            jQuery("#tblcontentsPager").find("#first, #prev, input.selbox, #sp_1, #sp_2, #next, #last").hide();
          };

In ver 3.7, I think, some of the controls have changed names. I have tried to figure this out by reading grid.base.js but interpreting javascript is not something I do well.

Can anyone tell me the names of these controls?

Is there a better way (in ver 3.7) to do what I want to do? The number of records to be returned depends on a setting on the web page, not available at the time that I define the jqGrid so it would still have to be dynamically set.

Thanks
