javascript - Mapping an array of strings to results in Select2 -

i've got json string

{"plaats":["rottevalle","rotterdam"]} 

and "rottevalle , rotterdam" item in selectbox select2

i've got code.

$("#plaats").select2({     minimuminputlength: 3,     tags: [],     ajax: {         url: 'plaatsen.php',         datatype: 'json',         delay: 250,         data: function (params) {             return {                 q: params.term, // search term                 page: params.page             };         },         processresults: function (data) {             return {                 results: $.map(data, function(obj) {                     return { id: obj.plaats, text: obj.plaats };                 })             };         }     } }); 

problem don't understand how plaats data within processresults.

the issue passing full response $.map instead of plaats key of that.

$("#plaats").select2({     minimuminputlength: 3,     tags: [],     ajax: {         url: 'plaatsen.php',         datatype: 'json',         delay: 250,         data: function (params) {             return {                 q: params.term, // search term                 page: params.page             };         },         processresults: function (data) {             return {                 results: $.map(data.plaats, function(obj) {                     return { id: obj, text: obj };                 })             };         }     } });
