双击在Firefox中有效，但在chrome中无效（Python / Selenium）

Question

I have an element that requires a double_click().perform() action. It works great in Firefox, but doesn't in Chrome. A single click displays a menu, but a double click takes you to a directory. Here is my python/selenium step:

(webdriver.ActionChains(self.browser)).double_click(self.browser.find_element_by_id('nav-link-shopall')).perform()

The error message returns that the text I'm wanting to verify exists does not exist. Which is true if the double_click().perform() doesn't do its job.

I'm using Python 2.7.8 and Selenium 2.45.0.

I'm using Amazon.com as an example because the behavior is the same as the proprietary code I am testing. So here is the HTML code I'm attempting to click:

<div class="nav-left">
    <div id="nav-shop">
         <a href="/gp/site-directory/ref=nav_shopall_btn" class="nav-a nav-a-2" data-nav-tabindex="15" id="nav-link-shopall" tabindex="1">
             <span class="nav-line-1">Shop by</span>
             <span class="nav-line-2">"Department"
                 <span class="nav-icon nav-arrow" style="visibility:visible;"></span>
             </span>
         </a>
      </div>
    </div>

Answer 1

Try this:

variable =  self.browser.find_element_by_id('nav-link-shopall')
actions = ActionChains(driver)
actions.move_to_element(variable)
actions.double_click(variable)
actions.perform()

You should use move to element.
