Ruby Watir Gem，表单输入超时
Ruby Watir Gem, Timing Out on Form Input
我正在练习使用 Watir、Mechanize 和 Nokigiri gems 进行网页抓取。
我 运行遇到了我的 Watir 脚本的问题。我的计划是通过 http://tripadvisor.com/ 获取航班价格列表。当我 运行 脚本时，Chrome 浏览器正常打开，脚本继续填写表单的第一部分，起点和终点，然后停止。这是我收到的错误消息：
This code has slept for the duration of the default timeout waiting for an Element to be present. If the test is still passing, consider using Element#exists? instead of rescuing UnknownObjectException

这是我的代码：
require 'watir'
browser = Watir::Browser.new
browser.goto('https://tripadvisor.com/CheapFlightsHome')
browser.input(name: 'orig').send_keys('Boston, MA - Logan International Airport (BOS)')
browser.input(name: 'dest').send_keys('Milan, Italy - All Airports (MIL)')
browser.input(name: 'rt_leaveday').send_keys('1')
browser.input(name: 'rt_leavemonth').send_keys('06/2017')
browser.input(name: 'retday').send_keys('30')
browser.input(name: 'leavemonth').send_keys('06/2017')
browser.input(value: 'Search Flights').click
puts browser.url
browser.quit
无法在 rt_leaveday 或 rt_leavemonth 上设置值，因为它们是隐藏输入。但是你可以执行一个脚本来点击 dateselector:
require 'watir'
browser = Watir::Browser.new
browser.goto('https://tripadvisor.com/CheapFlightsHome')
browser.text_field(name: 'orig').set('Boston, MA - Logan International Airport (BOS)')
browser.text_field(name: 'dest').set('Milan, Italy - All Airports (MIL)')
browser.execute_script('document.querySelector(".in_date").click()')
browser.execute_script('document.querySelector(".day_28").click()')
browser.execute_script('document.querySelector(".out_date").click()')
browser.execute_script('document.querySelector(".day_2").click()')
browser.span(id: "CHECK_FARES_BUTTON").fire_event :click
puts browser.url
browser.quit
