方法在数据为静态时工作,在从promise获取数据时归档

我有一个场景,比如我需要从api请求中获取一些数据,并在此基础上在屏幕上显示图像。

 return Class.extend({

      loadData: function (callbacks) {
        callbacks.onSuccess(
          [
            {
              "id":"1",
              "title":"Apple",
              "img" : "static/img/fruit/apple.png"
            },
            {
              "id":"2",
              "title":"Banana",
              "img" : "static/img/fruit/banana.png"
            },
            {
              "id":"3",
              "title":"Grapes",
              "img" : "static/img/fruit/grapes.png"
            },
            {
              "id":"4",
              "title":"Orange",
              "img" : "static/img/fruit/orange.png"
            },
            {
              "id":"5",
              "title":"Peach",
              "img" : "static/img/fruit/peach.png"
            },
            {
              "id":"6",
              "title":"Pear",
              "img" : "static/img/fruit/pear.png"
            }
          ]

        );
      }
    });

当我使用上面的代码时,它工作得很好,但我需要来自api的数据,所以我实现了一个获取数据的方法,我也创建了一个承诺,但这个承诺不起作用

 return Class.extend({
      // You will probably want to do something more useful then returning static data
      loadData: function (callbacks) {
        callbacks.onSuccess(
          evtBind().then(function (res) {
            console.log("res", res); 
            return res; 
          })
        );
      }
    });

function evtBind() {

  var device = RuntimeContext.getDevice();
  var get = function () {
    return new Promise(function (resolve, reject) {
      // do a thing, possibly async, then…

      device.executeCrossDomainGet('http://localhost:3000/result', {
        onSuccess: function (responseObject) {

          resolve(responseObject);

        },
        onError: function (response) {
          reject(response);
        }
      });
    });
  };
  return get();

}

我的代码与上面的代码类似。有人能帮我解决这个问题吗。
