使用AjaxDatasrcDatatable顯示資料時出現問題

我有一個資料表，我試圖從 API URL 獲取資料。問題是我已經獲取了所有資料并處理并存盤到一個名為 return_data 的陣列中，但我的資料表沒有顯示該陣列中的資料。

$(document).ready(function() {

    $('#datatable2').DataTable({

  'ajax':{
      'type'   : 'GET',
      'url'    : 'https://api-apollo.pegaxy.io/v1/pegas/owner/user/0xc580Aaf1D3C119E050AAEBf51D8cf912c8183A0A',
      'dataSrc': function(data){

          for(i=0; i<data1.length; i  ){
          var return_data = new Array();

              id = data[i].id;
              name = data[i].name;

              var url1 = 'https://api-apollo.pegaxy.io/v1/game-api/pega/' id;
              var url2 = 'https://api-apollo.pegaxy.io/v1/game-api/race/history/pega/' id;

              $.when($.getJSON(url1), $.getJSON(url2)).done(function(data2, data3){

                  id = data2[0].pega.id;
                  name = data2[0].pega.name;

                  var gold = 0, silver = 0, bronze = 0, total = 0, races = 0;

                  for(j=0; j<data3[0].data.length; j  ){

                      var today = new Date();
                      var yesterday = new Date(today);
                      yesterday.setDate(today.getDate() - 1);
                      today = today.toLocaleDateString();
                      yesterday = yesterday.toLocaleDateString();

                      var raced_date = moment(data3[0].data[j].updatedAt, 'YYYY-MM-DD').format('DD/MM/YYYY');    
                      var position   = data3[0].data[j].position;
                      var reward = data3[0].data[j].reward;

                      if(raced_date == today){
                              races  ;
                          if(position == 1){
                              gold  ;
                          }else if(position == 2){
                              silver  ;
                          }else if(position == 3){
                              bronze  ;
                          }
                          total  = reward;
                      }

                  }

                  return_data.push({
                      'Name': name,
                      'Races' : races,
                      'Gold'  : gold,

                      'Bronze' : bronze,
                      'Total' : total
                  })

// console.log(name ' = Races: ' races ', Gold: ' gold ', Silver: ' silver ', Bronze: ' bronze ' = ' total);

              });

          }
          console.log(return_data);
          return return_data;

uj5u.com熱心網友回復：

datatable 的 dataSrc 不會等待在其中進行的 ajax 呼叫。它在獲得第一次呼叫的結果后立即運行。

這是一個解決方法

var return_data = new Array();
