Select item from chosen js select with Capybara and Selenium

gistfile1.rb

def select_from_chosen(item_text, options)
  field = find_field(options[:from])
  option_value = page.evaluate_script("$(\"##{field[:id]} option:contains('#{item_text}')\").val()")
  page.execute_script("$('##{field[:id]}').val('#{option_value}')")
end

Great work. I've taken a different route to this. Rather than change the hidden select then do the update I've chosen to simulate user interaction. I've tested it with Webkit and Selenium and it works happily. You can check it out here: https://gist.github.com/4102026

Thank you for this snippet! Awesome.

Yeeees!! :-)

You can also overwrite Capybara's own select method and incorporate the above changes.
This way you would be able to target both regular select elements as well as chosen ones.

def select(value, options={})
    if options.has_key?(:from)
        element = find(:select, options[:from]).find(:option, value)
        if element.visible?
            element.select_option
        else
            field = find_field(options[:from])
            option_value = page.evaluate_script("$(\"##{field[:id]} option:contains('#{value}')\").val()")
            page.execute_script("$('##{field[:id]}').val('#{option_value}')")
            page.execute_script("$('##{field[:id]}').trigger('liszt:updated').trigger('change')")
        end
    else
        find(:option, value).select_option
    end
end

@egjiri, I'm not sure if this is from some other code, but I'm finding that

element = find(:select, options[:from]).find(:option, value)

fails because the select is disabled and won't be returned by the Capybara finder. Did you not encounter this?

Calling this before using your select helped me:

  def enable_element(id)
    element = find(:xpath, "//*[@id='#{id}']")
    if element["disabled"]
      page.execute_script("$('##{id}').removeAttr('disabled')")
    end
  end

Anyone didn't work with Poltergeist (Phantom.js) :(

@deepj it works for me (poltergeist-1.1.0)

Actually I had to update the select list through the command given by @rheaton.

page.execute_script("$('##{field[:id]}').trigger('liszt:updated').trigger('change')")

Thanks so much for this. I used @rheaton 's snippet, and it ran beautifully.

If using @rheaton's snippet with Capybara 2.1, you will need to pass visible: false to find_field since Chosen hides the field.

+1 to @jgarber for this point. Just wasted days of my life looking for a fix:

field = find_field(options[:from], visible: false)

Fixes the failing tests.

@tjmcewan

I know it's been a long time, but it seems these two statements you added for supporting from a multiple-select,

page.execute_script("value = ['#{option_value}']\; if ($('##{field[:id]}').val()) {$.merge(value, $('##{field[:id]}').val())}")
option_value = page.evaluate_script("value")

seem to break functionality for a single select if there is a default value selected. Thought I would mention it here since this is still an active thread.

For capybara 2, visible: true is the default, so this doesn't work as is. Changed the first line to:

field = find_field(options[:from], visible: false)

+1 for pduey's comment I also had to add visible: false

Here is an updated version of @Macrow 's chosen_select.rb

# Support for multiple selects (just call select_from_chosen as many times as required):
module ChosenSelect
  def select_from_chosen(item_text, options)
    field = find_field(options[:from], visible: false)
    option_value = page.evaluate_script("$(\"##{field[:id]} option:contains('#{item_text}')\").val()")
    page.execute_script("value = ['#{option_value}']\; if ($('##{field[:id]}').val()) {$.merge(value, $('##{field[:id]}').val())}")
    option_value = page.evaluate_script("value")
    page.execute_script("$('##{field[:id]}').val(#{option_value})")
    page.execute_script("$('##{field[:id]}').trigger('chosen:updated')")
  end  
end

RSpec.configure do |config|
  config.include ChosenSelect
end

Thanks @michaelbrawn!!!!

I'm using cucumber-1.3.16 and rspec-3.0.3 and I've got a problem with

RSpec.configure do |config|
  config.include ChosenSelect
end 

When I run cucumber I get a "undefined method `configure' for RSpec:Module (NoMethodError)".

I've replaced it with "World(ChosenSelect)" and it works!!!! this is how the complete module code looks like:

# Support for multiple selects (just call select_from_chosen as many times as required):
module ChosenSelect
  def select_from_chosen(item_text, options)
    field = find_field(options[:from], visible: false)
    option_value = page.evaluate_script("$(\"##{field[:id]} option:contains('#{item_text}')\").val()")
    page.execute_script("value = ['#{option_value}']\; if ($('##{field[:id]}').val()) {$.merge(value, $('##{field[:id]}').val())}")
    option_value = page.evaluate_script("value")
    page.execute_script("$('##{field[:id]}').val(#{option_value})")
    page.execute_script("$('##{field[:id]}').trigger('chosen:updated')")
  end  
end

World(ChosenSelect)

Can confirm this works like a charm. Thanks a lot! 👯

(RSpec 3, Capybara 2.4.1)

Thanking you!!!

When to use last one with Ember.js got a problem: it doens't update binded values. So just add .change() at the end and it will work as expected.

# Support for multiple selects (just call select_from_chosen as many times as required):
module ChosenSelect
  def select_from_chosen(item_text, options)
    field = find_field(options[:from], visible: false)
    option_value = page.evaluate_script("$(\"##{field[:id]} option:contains('#{item_text}')\").val()")
    page.execute_script("value = ['#{option_value}']\; if ($('##{field[:id]}').val()) {$.merge(value, $('##{field[:id]}').val())}")
    option_value = page.evaluate_script("value")
    page.execute_script("$('##{field[:id]}').val(#{option_value})")
    page.execute_script("$('##{field[:id]}').trigger('chosen:updated')")
    page.execute_script("$('##{field[:id]}').change()")
  end  
end

World(ChosenSelect)

Without needing to call evaluate_script, this also works with Capybara 2.4.4, Capybara-webkit 1.4.1 and Rspec 3.2.2, using Chosen 1.4.1:

find("#field_id_chosen").trigger("mousedown")
find("#field_id_chosen ul.chosen-results li", :text => "Item Text").trigger("mouseup")

For those of you using rails who need to escape javascript when setting option_value the first time.

include ActionView::Helpers::JavaScriptHelper

in the Module/Class where this method lives, and change

option_value = page.evaluate_script("$(\"##{field[:id]} option:contains('#{item_text}')\").val()")

to

option_value = page.evaluate_script("$('##{field[:id]} option:contains(\"#{j item_text}\")').val()")

---

As an aside, if your select box is prepopulated, and you want to CHANGE the value, you must clear the value of the select box before calling select_from_chosen, or it will attempt to select both values.

It only works for a single selection of chosen dropdown but not on grouped options chosen select

Hey guys,

The implementation of @flexybiz above seems to work fine, however if, for whatever reason, I run select_from_chosen two or more times on the same field, this will select multiple options even though my chosen is configured to be a standard select, not a multiple one.

My workaround was creating deselect_from_chosen.

So in case you guys need to deselect fields in your tests, here's how I did it:

  def deselect_from_chosen(field)
    field = find_field(field, visible: false)
    page.execute_script("$('##{field[:id]}').val('').trigger('change').trigger('chosen:updated')")
  end

Funny to find this gist again 4 years later with so much discussion :-). I just needed this again, this one based on the snippet by @corporealfunk works well in Selenium:

def select_from_chosen(item_text, options)
  field = find_field(options[:from], :visible => false)
  find("##{field[:id]}_chosen").click
  find("##{field[:id]}_chosen ul.chosen-results li", :text => item_text).click
end

For deselecting a specific value :

def deselect_from_chosen(item_text, options)
  field = find_field(options[:from], visible: false)
  page.execute_script("$(\"##{field[:id]} option:contains('#{item_text}')\").removeAttr('selected')")
  page.execute_script("$('##{field[:id]}').trigger('chosen:updated')")
end

Here's another deselect function that's more in-line with @thejsc's approach. I like this approach because it triggers the change hook.

def deselect_from_chosen(item_text, options)
  field = find_field(options[:from], visible: false)
  find("##{field[:id]}_chosen ul.chosen-choices li.search-choice", :text => item_text).find("a.search-choice-close").click
end

For anyone whos interested in just selecting whichever option is first without having to know the text

def select_first_from_chosen(from)
  field = find_field(from, visible: false)
  find("##{field[:id]}_chosen").click
  first("##{field[:id]}_chosen ul.chosen-results li").click
end

Use like this: select_first_from_chosen('post[name]')

To guarantee an exact match rather than a partial match aka - find 'OR' and not match 'MORE'
replace
the line

find("##{field[:id]}_chosen ul.chosen-results li", text: item_text).click

with

find("##{field[:id]}_chosen ul.chosen-results li", text: /\A#{Regexp.quote(item_text)}\z/).click
