Capybara: Select an option by value not text
提问by Paul
For the HTML
对于 HTML
<select id="date">
<option value="20120904">Tue 4 Sep 2012</option>
<option value="20120905">Wed 5 Sep 2012</option>
<option value="20120906">Thu 6 Sep 2012</option>
</select>
I have the following Capybara Ruby code:
我有以下 Capybara Ruby 代码：
select "20120905", :from => "date"
But this errors with:
但是这个错误：
cannot select option, no option with text '20120905' in select box 'date' (Capybara::ElementNotFound)
However, if I do
但是，如果我这样做
select "Wed 5 Sep 2012", :from => "date"
It's ok.
没关系。
Is it possible to select an option in Capybara by Valuenot Text?
是否可以通过Value而不是Text在 Capybara 中选择一个选项？
Thanks
谢谢

This will work to select an option by value:
这将用于按值选择一个选项：
find("option[value='20120905']").click
To maintain the scope of the selector you could wrap it in a within block as such:
为了保持选择器的范围，您可以将它包装在一个内块中，如下所示：
within '#date' do
find("option[value='20120905']").click
end

With Poltergeist as driver I can't click on an option like suggested in some of the other options above, instead you can do the following:
使用 Poltergeist 作为驱动程序，我无法单击上面其他一些选项中建议的选项，而是可以执行以下操作：
page.find_by_id('date').find("option[value='20120905']").select_option
page.find_by_id('date').find("option[value='20120905']").select_option

I wrote a helper method:
我写了一个辅助方法：
def select_by_value(id, value)
option_xpath = "//*[@id='#{id}']/option[@value='#{value}']"
option = find(:xpath, option_xpath).text
select(option, :from => id)
end
Save in a .rb file in spec/support/
保存在spec/support/中的 .rb 文件中
Example use:
使用示例：
before do
select_by_value 'some_field_id', 'value'
click_button 'Submit'
end

You can also achieve it by doing the following:
您还可以通过执行以下操作来实现它：
find_by_id('date').find("option[value='20120905']").click

That helper method is pretty clever. I would change it just a little bit:
这个辅助方法非常聪明。我会稍微改变一下：
def select_by_value(id, value)
option_xpath = "//*[@id='#{id}']/option[@value='#{value}']"
find(:xpath, option_xpath).click
end
or just:
要不就：
find(:xpath, "//select[@id='date']/option[@value='20120904']").click

In my case I have a few options with same text, that's the reason why I need select by value. Combining a few answers together I've found the best solution for me:
在我的情况下，我有几个具有相同文本的选项，这就是我需要按值选择的原因。结合几个答案，我找到了最适合我的解决方案：
def select_by_value(id, value)
option_xpath = "//*[@id='#{id}']/option[@value='#{value}']"
find(:xpath, option_xpath).select_option
end

You could also use capybara-uiwhich will look first to match the text, then to match the value.
您还可以使用capybara-ui，它首先查找匹配文本，然后匹配值。
# define your form widget, in this case in a role
class UserRole < Capybara::UI::Role
form :my_form do
select :my_select, 'my_select'
end
end
# then just submit your form params via #submit
role = UserRole.new
role.submit :my_form, my_select: '20120905'

Click using find_field works fine:
单击使用 find_field 工作正常：
find_field("date").find("option[value='20120905']").click
