javascript - How to access returned objects from query so that images can be displayed? -


parse.com , javascript.

the code below returning correct results, per screen shots, but..

how can return , access each of objects has been captured query? want use "pic" column held within _user class. @ moment images returning undefined.

    var currentuser = parse.user.current();   var friendrequest = parse.object.extend("friendrequest");       var query = new parse.query(friendrequest);     query.equalto("fromuser", currentuser);     query.equalto("status", "request sent");     //query.exists("pic");          query.find({               success: function(results) {         // if query successful, store each image url in array of image url's         imageurls = [];         (var = 0; < results.length; i++) {            var object = results[i];           imageurls.push(object.get('pic'));         }      // if imageurls array has items in it, set src of img element first url in array         for(var j = 0; j < imageurls.length; j++){             $('#imgs').append("<img src='" + imageurls[j] + "'/>");                          }       },       error: function(error) {         // if query unsuccessful, report errors         alert("error: " + error.code + " " + error.message);       }     });          // show signup or login page   </script> 

if images stored in relation array "pic" element in "friendrequest" have additional relation query retrieve array ....

this.collection = new userlist(); this.model = this.options.model;  // check whether user or role shoul b user         var relation = this.model.relation("users"); this.collection.query = relation.query();        var role = this.model.id; var rolename = this.model.get("name"); this.collection.fetch(); 

above module works parse._roles has "users" field - array of type relation

to work relation pointers in "user" , 'relation' query required. after fetch, in collection, have array of pointers want images.
