扩展leancloud js sdk 中的一些方法

leancloud.extension.js

var AV = require('avoscloud-sdk').AV;

AV.Query.prototype.findAll = function () {
  var self = this,
      data = [];
  self._limit = 1000;
  self._order = 'createdAt';

  return loop(avpromise(0), function (skip) {
    self._skip = skip;
    return self.find();
  });

  function avpromise(resolved) {
    return new AV.Promise(function (resolve) {
      resolve(resolved);
    });
  }

  function loop(promise, fn) {
    return promise.then(fn).then(function (rows) {
      data = data.concat(rows);
      return rows.length === self._limit ? loop(avpromise(self._skip + self._limit), fn) : avpromise(data);
    });
  }
};
