如何在Capybara和ChromeDriver中拖动jQuery滑块手柄? [英] How do I drag a jQuery slider handle from within Capybara and ChromeDriver?

问题描述

我能够执行以下代码来移动滑块手柄，但是不会发生浏览器中触发的事件.

I am able to execute the following code to move the slider handle, but the events triggered in the browser are not taking place.

page.execute_script(%Q($('#slider_handicap').slider('values',1,30)))

那正确地将右手柄设置为30，但是我需要它表现得就像我实际上是在握住鼠标并将手柄拖动到30然后释放.

That correctly sets the right handle to 30, but I need it to behave as if I were actually taking the mouse and dragging the handle to 30 then releasing.

推荐答案

我之前扩展了水豚的拖动功能.
它可以将元素移动给定的偏移量.

I extended capybara dragging before.
It can move elements by a given offset.

您可以尝试

module CapybaraExtension
  def drag_by(right_by, down_by)
    base.drag_by(right_by, down_by)
  end
end

module CapybaraSeleniumExtension
  def drag_by(right_by, down_by)
    resynchronize { driver.browser.action.drag_and_drop_by(native, right_by, down_by).perform }
  end
end

::Capybara::Selenium::Node.send :include, CapybaraSeleniumExtension
::Capybara::Node::Element.send :include, CapybaraExtension

然后

page.find('#slider_handicap').drag_by(30, 0)

但是它可能不适合滑块的比例.

But it may not suit the slider's scale.

原始文件是

• Capybara :: Node :: Element#drag_to
• Capybara :: Selenium :: Node#drag_to
• Selenium :: WebDriver :: ActionBuilder drag_and_drop和drag_and_drop_by

• Capybara::Node::Element#drag_to
• Capybara::Selenium::Node#drag_to
• Selenium:: WebDriver::ActionBuilder drag_and_drop and drag_and_drop_by

有几句话要小心.

• 此扩展名可能取决于驱动程序的类型和版本 驱动程序.
• 这种带有拖拽的测试可能会导致维护困难.

• This extension could depend on the type of driver and the version of driver.
• This kind of test with dragging could lead to difficulty of maintainance.
