如何使用 Capybara + Poltergeist 将文本设置到 Summernote 文本区域

2023-12-12

我有一个正在使用的文本区域夏日笔记我给它设置了 onChange 事件。我想用 RSpec + Capybara + Poltergeist 编写测试来确认 onChange 事件正常工作。

据我检查，浏览器中显示的文本区域实际上是带有“note-editable”css 类的 div 标签。如何为其设置文本并触发 onChange 事件？

我写了这样的代码，但出现错误Capybara::ElementNotFound: Unable to find field "Some label":

visit edit_foo_path
fill_in 'Some label', with: 'Foo bar'

EDIT

我为此问题创建了一个示例应用程序：

咖啡脚本

$ ->
  $('.summernote').summernote()

RSpec

require 'rails_helper'

feature 'Blogs' do
  scenario 'Create blog' do
    visit new_blog_path
    fill_in 'Title', with: 'Hello, world!'
    fill_in 'Content', with: 'This is awesome blog.'
    click_button 'Create Blog'
    expect(page).to have_content 'Blog was successfully created.'
    expect(page).to have_content 'Hello, world!'
    expect(page).to have_content 'This is awesome blog.'
  end

  scenario 'Create blog with JS', js: true do
    visit new_blog_path
    fill_in 'Title', with: 'Hello, world!'
    pending 'Capybara::ElementNotFound: Unable to find field "Content"'
    fill_in 'Content', with: 'This is awesome blog.'
    click_button 'Create Blog'
    expect(page).to have_content 'Blog was successfully created.'
    expect(page).to have_content 'Hello, world!'
    expect(page).to have_content 'This is awesome blog.'
  end
end

将Summernote更新到0.8.2后，find('div[contenteditable]').set('This is awesome blog.')不起作用。

我必须通过调用 Summernote APIexecute_script like:

script = <<-JS
$('.some-field').summernote('editor.insertText', 'This is awesome blog.');
JS
execute_script(script)

EDIT

将Summernote更新到0.8.2后，find('div[contenteditable]').set('This is awesome blog.')不起作用。

抱歉，这不是我想说的。我应该这样说：

将Summernote更新到0.8.2后，find('div[contenteditable]').set('This is awesome blog.')不会触发 Summernotes 的 onChange 回调。所以我不得不打电话execute_script.

我必须在我的规范中测试 onChange 行为。

EDIT 2

正如托马斯·沃波尔所写，send_keys可以使用方法代替execute_script。谢谢托马斯·沃波尔！

find('div[contenteditable]').send_keys('This is awesome blog.')
