如何用水豚填充隐藏的字段？ [英] How to fill hidden field with Capybara?

问题描述

我已经发现，当我想将值设置为文本字段，文本区域或密码字段时，我可以将ID，名称或标签用作某物在 fill_in一些东西，：with => some_value 。但是，当我尝试将值设置为< input type = hidden> 字段时，这种方法失败了（我想这样做，因为这些通常是在客户端填充的我分别测试的脚本）。如何使用水豚设置这样的隐藏字段？

I've already found that when I want to set value to text field, text area or password field, I can use id, name or label as something in fill_in something, :with => some_value. However such approach fails when I try to set value to <input type="hidden"> field (and I want to do it because those are normally filled client-side scripts which I test separately). How could I set such a hidden field with Capybara? Is it possible?

HTML：

<input id='offer_latitude' name='offer[latitude]' type='hidden'>
<input id='offer_longitude' name='offer[longitude]' type='hidden'>

spec：

describe "posting new offer" do
  it "should add new offer" do
    visit '/offer/new'
    fill_in 'offer[latitude]', :with => '11.11'
    fill_in 'offer[longitude]', :with => '12.12'
    click_on 'add'
  end
end

给出：

1) posting new offer should add new offer
   Failure/Error: fill_in 'offer[latitude]', :with => '11.11'
   Capybara::ElementNotFound:
     cannot fill in, no text field, text area or password field with id, name, or label 'offer[latitude]' found

推荐答案

您需要找到隐藏字段并设置其值。有几种方法，这可能是最简单的

You need to locate the hidden field and set its value. There are a couple ways, this is probably the simplest

find(:xpath, "//input[@id='my_hidden_field_id']").set "my value"

如果您在生产环境中执行client_side脚本，您只需告诉capybara使用与JavaScript兼容的驱动程序即可运行

If you're executing a client_side script in production, you could just tell capybara to run it with a javascript-compliant driver

page.execute_script("$('hidden_field_id').my_function()")
