ruby - 用机械化填写日历？

Question

我想填写 www.vegas.com/lasvegastraveldeals 的日历日期字段。

到目前为止，我似乎无法使该value方法起作用。这是我的代码：

require 'mechanize'

agent = Mechanize.new
page = agent.get('http://www.vegas.com/lasvegastraveldeals/')
vegas_form = page.form('gs')
vegas_form.q = 'DFW'
departure = vegas_form.field_with(:id => 'departureDatec12')
departure.value = "05/16/2014"
pp page

我收到此错误：

vegas_scraper.rb:9:in `<main>': undefined method `value=' for nil:NilClass (NoMethodError)

有什么建议么？

Answer 1

如果字段名称是departureDate那么这应该工作：

form['departureDate'] = '05/16/2014'

Answer 2

您没有找到带有 id 的输入departureDatec12。根据页面的源代码是departureDate2。所以试试这个

departure = vegas_form.field_with(:id => 'departureDate2')
