量角器:无法访问父函数中定义的闭包中的变量

Question

我在我的一个JS文件中有以下代码.

// test/lib/UserHelper.js

'use strict';
var Firebase = require('firebase');

exports.createUser = function (email, password) {
  browser.executeAsyncScript(function (done) {
    var $firebaseSimpleLogin = angular.inject(['ng', 'firebase']).get('$firebaseSimpleLoging');
    var firebaseRef = new Firebase('https://urltoapplication.firebaseio.com');
    var auth = $firebaseSimpleLogin(firebaseRef);

    auth.$createUser(email, password);

    done();
  });
};

我在我的测试中称之为:

// test/settings/company.spec.js

'use strict';
var user = require('../lib/UserHelper');

describe('company specs', function () {

  beforeEach(function () {
    user.createUser('test@test.com', 'test');
  });
});

要在通话user.createUser('test@test.com', 'test');中beforeEach回调失败UnknownError: email is not defined的auth.$createUser(email, password);.

为什么email回调函数中无法访问变量？是否可以传播传递给函数的关闭函数的参数createUser？

根据Andres D的回答,这对我有用.

exports.createUser = function (data) {
  browser.executeAsyncScript(function (data, done) {
    var $firebaseSimpleLogin = angular.inject(['ng', 'firebase']).get('$firebaseSimpleLoging');
    var firebaseRef = new Firebase('https://urltoapplication.firebaseio.com');
    var auth = $firebaseSimpleLogin(firebaseRef);

    auth.$createUser(data.email, data.password);

    done();
  }, data);
};

这是我在角度聚会期间使用的一个工作示例:

您只能将一个参数传递给executeAsyncScript.如果您需要传递多个值,我建议您传递一个对象:

module.exports = {
  create: function(data) {
    return browser.executeAsyncScript(function(data, callback) {
      var api = angular.injector(['ProtractorMeetupApp']).get('apiService');
      api.member.save(data, function(newItem) {
        callback(newItem._id);
      })
    }, data);
  }
};

create({email: 'sdf@sdf.com', password: 'sfd'}).then(function(response){
  // Handle response here.
})
