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

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
