capybara - 使用xPath查找离开内部作用域 [英] capybara - Find with xPath is leaving the within scope

问题描述

我试图使用默认的Rails日期，时间和日期时间字段与Capybara构建一个日期选择器。我使用方法内的找到字段的选择框，但是当我使用xPath找到正确的框，它留下 scope，并找到元素页面上的第一个匹配项。

这里是我使用的代码。我测试的页面有2个datetime字段，但我只能得到它改变第一，因为这个错误。目前我有一个div容器，id，包装了datetime字段，但我计划切换代码找到的标签。

  module Marketron 
 module DateTime 
 
 def select_date（field，options = {}）
 date_parse = Date.parse（options [：with]）
 
 year = date_parse.year.to_s 
 month = date_parse.strftime（'％B'）
 day = date_parse.day.to_s 
 
 within（div＃ ＃{field}）do 
 find（：xpath，// select [contains（@id，\_＃{FIELDS [：year]} \）] 
 find（：xpath，// select [contains（@id，\_＃{FIELDS [：month]} \）]。 xpath//选择[包含（@id，\_＃{FIELDS [：day]} \）]）。select（day）
 end 
 
 end 
 
 def select_time（field，options = {}）
需要time
 time_parse = Time.parse（options [：with]）
 
 hour = time_parse.hour.to_s.rjust（2，'0'）
 minute = time_parse.min.to_s.rjust（2，'0'）
 
 within {field}）do 
 find（：xpath，// select [include（@id，\_＃{FIELDS [：hour]} \）] 选项[包含（@id，\_＃{FIELDS [：分]）选项[contains（@value，'＃{hour}'） } \）]）。find（：xpath，option [contains（@value，'＃{minute}'）]）。select_option 
 
 end 
 $ b b end 
 
 def select_datetime（field，options = {}）
 select_date（field，options）
 select_time（field，options）
 end 
 b $ b private 
 
 FIELDS = {year：1i，month：2i，day：3i，hour：4i，minute：5i} 
 
 end 
 end

解决方案

您应该在xpath中指定要从当前节点开始，通过向开始添加。 / p>

  find（：xpath，.//select[contains(eeid，\_＃{FIELDS [：year] } \）]）
  

示例：

我测试了一个HTML页面（希望不会过于简化你的页面）：

 < html> 
< div id ='div1'> 
< span class ='container'> 
< span id ='field_01'>栏位1< / span> 
< / span> 
< / div> 
< div id ='div2'> 
< span class ='container'> 
< span id ='field_02'>栏位2< / span> 
< / span> 
< / div> 
< / html> 
 

使用within方法时，您可以在执行此操作时看到问题：

  within（div＃div1）{puts find（：xpath，// span [contains（@id，\field\ ）]）。text} 
＃=>字段1 
 within（div＃div2）{puts find（：xpath，// span [contains（@id，\field\）]text} 
＃ =>字段1 
  

但你可以看到，但是指定xpath来查看当前节点code>。），你会得到你想要的结果：

  ＃div1）{puts find（：xpath，。//span[contains(@id，\field\）]）。字段1 
 within（div＃div2）{puts find（：xpath，。//span[contains(eeid，\field\））。text} 
 ＃=>字段2 
  

I am trying to build a date selector with Capybara using the default Rails date, time, and datetime fields. I am using the within method to find the select boxes for the field but when I use xPath to find the correct box it leaves the within scope and find the first occurrence on the page of the element.

Here is the code I am using. The page I am testing on has 2 datetime fields but I can only get it to change the first because of this error. At the moment I have an div container with id that wraps up the datetime field but I do plan on switching the code to find by the label.

module  Marketron
  module DateTime

    def select_date(field, options = {})
      date_parse = Date.parse(options[:with])

      year = date_parse.year.to_s
      month = date_parse.strftime('%B')
      day = date_parse.day.to_s

      within("div##{field}") do
        find(:xpath, "//select[contains(@id, \"_#{FIELDS[:year]}\")]").select(year)
        find(:xpath, "//select[contains(@id, \"_#{FIELDS[:month]}\")]").select(month)
        find(:xpath, "//select[contains(@id, \"_#{FIELDS[:day]}\")]").select(day)
      end

    end

    def select_time(field, options = {})
      require "time"
      time_parse = Time.parse(options[:with])

      hour = time_parse.hour.to_s.rjust(2, '0')
      minute = time_parse.min.to_s.rjust(2, '0')

      within("div##{field}") do
        find(:xpath, "//select[contains(@id, \"_#{FIELDS[:hour]}\")]").find(:xpath, "option[contains(@value, '#{hour}')]").select_option
        find(:xpath, "//select[contains(@id, \"_#{FIELDS[:minute]}\")]").find(:xpath, "option[contains(@value, '#{minute}')]").select_option

      end

    end

    def select_datetime(field, options = {})
      select_date(field, options)
      select_time(field, options)
    end

    private

      FIELDS = {year: "1i", month: "2i", day: "3i", hour: "4i", minute: "5i"}

  end
end

解决方案

You should specify in the xpath that you want to start with the current node by adding a . to the start:

find(:xpath, ".//select[contains(@id, \"_#{FIELDS[:year]}\")]")

Example:

I tested an HTML page of this (hopefully not over simplifying your page):

<html>
    <div id='div1'>
        <span class='container'>    
            <span id='field_01'>field 1</span>
        </span>
    </div>
    <div id='div2'>
        <span class='container'>
            <span id='field_02'>field 2</span>
        </span>
    </div>  
</html>

Using the within methods, you can see your problem when you do this:

within("div#div1"){ puts find(:xpath, "//span[contains(@id, \"field\")]").text }
#=> field 1
within("div#div2"){ puts find(:xpath, "//span[contains(@id, \"field\")]").text }
#=> field 1

But you can see that but specifying the xpath to look within the current node (ie using .), you get the results you want:

within("div#div1"){ puts find(:xpath, ".//span[contains(@id, \"field\")]").text }
#=> field 1
within("div#div2"){ puts find(:xpath, ".//span[contains(@id, \"field\")]").text }
#=> field 2
