Question

我有一个使用Summernote的textarea，我将onChange事件设置为它。我想用RSpec + Capybara + Poltergeist编写测试来确认onChange事件是否有效。

据我检查，浏览器中显示的textarea实际上是带有'note-editable'css类的div标签。如何设置文本并触发onChange事件？

我写了这样的代码，但收到错误Capybara::ElementNotFound: Unable to find field "Some label"：

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

修改

我为此问题创建了一个示例应用：

Answer 1

Capybaras fill_in仅适用于html表单元素。由于您的页面的JS版本使用具有contenteditable属性的DIV作为要填充的文本区域，因此#fill_in将不起作用。相反，你需要找到div并直接调用#set。在您的项目中，以下内容应该有效

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

Answer 2

将Summernote更新为0.8.2后，find('div[contenteditable]').set('This is awesome blog.')无效。

我必须通过execute_script调用Summernote API，如：

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

修改

将Summernote更新为0.8.2后，find('div[contenteditable]').set('This is awesome blog.')无效。

对不起，这不是我想说的。我应该这样说：

将Summernote更新为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给execute_script。

我必须在我的规范中测试onChange行为。

正如Thomas Walpole所写，可以使用send_keys方法代替execute_script。谢谢Thomas Walpole！

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