javascript - Function in object is being declared as not a function -


this question has answer here:

so have created small table row generator json. when started building hadn't put in object , worked absolutley fine.

after, made abstract , needes parameters passed it. put in object re use other sets of data. however, after putting in object console message:

typeerror: this.gettablerow not function

but... function:

gettablerow: function(data) {     row = "<tr>";      (i in data) {         row += "<td>" + data[i] + "</td>";     }      row += "</tr>";      return row; }

here full script have in context:

var datacollector = {      basedataurl: 'http://tourn.dev/data/',      displaydatatable: function(datapath, tableidentifier, datakeys, dataopts) {          $.getjson(this.buildpath(datapath, dataopts), function (dataset) {             (k in dataset) {                  d = dataset[k];                  data = [];                  (i in datakeys) {                     data[i] = d[datakeys[i]];                 }                 ;                  $(tableidentifier).append(this.gettablerow(data));             }         })     },      getdataurl: function() {         return this.basedataurl;     },      buildpath: function(datapath, dataopts) {         path = this.getdataurl();          if (datapath != null) {             path += datapath;         }          if (dataopts != null) {             if (dataopts.constructor === array) {                 (i in dataopts) {                     path += '/' + dataopts[i];                 }             } else {                 path += '/' + dataopts;             }         }          return path;     },      gettablerow: function(data) {         row = "<tr>";          (i in data) {             row += "<td>" + data[i] + "</td>";         }          row += "</tr>";          return row;     } };

this.gettablerow not inside getjson context. store this outside call.

displaydatatable: function(datapath, tableidentifier, datakeys, dataopts) {     var self = this; // store     $.getjson(this.buildpath(datapath, dataopts), function (dataset) {         (k in dataset) {              d = dataset[k];              data = [];              (i in datakeys) {                 data[i] = d[datakeys[i]];             }             ;              $(tableidentifier).append(self.gettablerow(data)); //this in correct scope         }     }) }
