Question

我试图浏览教程http://angular.github.io/protractor/#/tutorial

当我尝试使用.first()或.last()方法获取元素时测试失败并出现错误：

TypeError Object [object Object]没有方法＆＃39; indexof＆＃39;

这里是spec.js

var firstNumber = element(by.model('first'));
var secondNumber = element(by.model('second'));
var go = element(by.id('gobutton'));
var latest = element(by.binding('latest'));
var history = element.all(by.repeater('result in memory'));

beforeEach(function() {
    browser.get('http://juliemr.github.io/protractor-demo/');
});
//...other tests passed

it('should have a history', function(){
    firstNumber.sendKeys(1);
    secondNumber.sendKeys(2);
    go.click();

    expect(history.count()).toEqual(1);
    // expect(history.last()).toContain('1 + 2'); //error here

    firstNumber.sendKeys(3);
    secondNumber.sendKeys(5);
    go.click();

    expect(history.count()).toEqual(2);
    // expect(history.first()).toContain('3 + 5'); //and here
});

关于这个ElementArrayFinder API它应该运行正常

我正在使用

jasmine-1.3.1
量角器版本1.8.0

您可能希望期待元素的文本：

expect(history.last().getText()).toContain('1 + 2');
expect(history.first().getText()).toContain('3 + 5');

量角器ElementArrayFinder .last（）[object Object]没有方法'indexof'
