Hi there

I tried to load a SOLR json result in jqGrid, but unfortunately the SOLR result (I have no control of) does not contain page and total, so I needed a way to calculate the value from the "start" and "numFound" fields incorporated in the SOLR result.

To make this work, I needed to add

if( typeof expr === 'function') return expr(obj);

in the getAccessor() function (around line 453 in the grid.base.js source). Now I can write

       jsonReader: {
               root: "response.docs",
               records: "response.numFound",
               total: function(data){
                    return Math.ceil( data.response.numFound /
                                      data.response.docs.length )
               },

               page: function(data){
                     return Math.floor( data.response.start /
                                        desc.rowNum )+1
               },

               id: "id",
               repeatitems: false
        }

to calculate the needed values. Maybe this is useful to others here, so I thought to just post it.

The whole getAccessor definition in grid.base.js now looks like this:

        getAccessor = function(obj, expr) {
           var ret,p,prm;
            if( typeof expr === 'function') return expr(obj); // this line is new – nothing else
           ret = obj[expr];
           if(ret===undefined) {
                if ( typeof expr === 'string' ) {
                   prm = expr.split('.');
               }
               try {
                   if(prm.length) {
                       ret = obj;
                        while (ret && prm.length) {
                           p = prm.shift();
                           ret = ret[p];
                       }
                   }
               } catch (e) {}
           }
           return ret;
       }

Best regards

Mathias
