Modifying the jqGrid editurl

I've been battling some unfamiliar jqGrid code and I'm hoping someone with more insight can move me toward where I need to be in far less time than it's taken me to get nowhere.

I have a grid displaying registration info. When I click on a row, a Refund button appears. If I click that, a request is sent to the url defined in the grid's editurl property. That much I think I understand reasonably well. Maybe. Anyway, I need to capture that Refund click in order to launch a dialog (maybe a confirm() box) and modify the editurl with the return value before it's sent.

The existing column as defined in colModel looks like this:

{ name:'options',sortable:'false',width:60,editable:true,edittype:'button',
  editoptions:{
    value:'Refund', 
    dataEvents:[{
      type:'click',
      fn: function(e){ 
        jQu开发者_运维知识库ery('#registrationsTable').jqGrid('saveRow',lastRegistrationSelected,showStatus);
      }
    }]
  }
}

Any insight would be appreciated. I'm getting completely bogged down in the docs.

Thanks.

It seems to me that you can just use

jQuery('#registrationsTable').jqGrid('saveRow',lastRegistrationSelected,showStatus,
                                     anyUrl);

instead of

jQuery('#registrationsTable').jqGrid('saveRow',lastRegistrationSelected,showStatus);

Look at the possible parameters of the saveRow method. In you need an additional conformation dialog you can insert it before the call of saveRow method.
