javascript - How to reset the data after init , Select2 -


i use select2-4.0.0 have been struggling problem whole day update data.

i search every posts can update select2 data without rebuilding control, none have them work.

what need simple (a setter data):

i have diaglog, had select. every time open diaglog, ajax data keep in local array like:

when dialog open :

    var select2list=synctoloadthedata();//data select2     $('#search-user-select').select2({  //here when secondly executed, select2's data on ui not refreshed          data:select2list,         matcher: function(params, data){             var key = params.term;             if ($.trim(key) === '') {                 return data;             }             if( (matchkeyandpinyin(key,data.text))){                 return data;             }             return null;         }     }

but problem though list changing, select options not change @ all.please note in test case, every time open dialog, data server changed:

what had tried: 1.when init:

  data: function() { return {results: select2list}; }// not work show data @

2.when secondly open dialog:

  $( "#search-user-select").select2('data',newdata,true);//not work have new data

3.when secondly open:

   $("#search-user-select").select2("updateresults");//error, not have method

and other method directly change array's data(only 1 copy of data), none of them work.

i had same problem before, problem need update select2 after every ajax request new data.

and how fixed code.

         eventid = $(this).attr('id');              $.ajax({             url: 'ajaxgetalleventperons',             type: 'post',             datatype: 'json',             data: {id: eventid},         })         .done(function(data) {                   $("#select2_job").select2({                 minimuminputlength: 2,                 multiple:true,                  initselection : function (element, callback) {                 //var data = data;                    callback(data);                 },                  ajax: {                 url: "/ajaxgetallpersonforevent",                 datatype: 'json',                 quietmillis: 100,                 data: function (term) {                     return {                         term: term                     };                 },                 results: function (data) {                     var myresults = [];                     $.each(data, function (index, item) {                         myresults.push({                             'id': item.id,                             'text': item.fullname                         });                     });                     return {                         results: myresults                     };                 }                 }                 });
