Question

我正在使用selenium-python绑定来执行一些基本的浏览器测试。我需要单击一个默认不可见的元素。我已经通过is_displayed() method进行了检查。因此，我尝试使用execute_script方法通过使用以下代码使其可见，但我收到错误消息。这是一个常见的场景，我们需要让一个看不见的元素可见。必须有其他一些方法来绕过这类问题。如果有人在我的代码中指出了问题，那将会很有帮助。我可以在python代码中单击带有纯js的元素吗？

print "getting keyword ideas"
searches = driver.find_element_by_xpath("//*[contains(text(), 'Avg. monthly searches')]")
driver.execute_script("arguments.style.visibility='visible';", searches)

和错误消息：

<div id="gwt-debug-column-SEARCH_VOLUME_PRIMARY-header-0-0">
    <div style="text-align:right">Avg. monthly searches
        <span class="table-tooltip" id="gwt-debug-tooltip-4580983">&nbsp;</span>
        <br>
        </div>
    </div>

这是python代码：

print "getting keyword ideas"
driver.execute_script('document.getElementById("gwt-debug-column-SEARCH_VOLUME_PRIMARY-header-0-0").style.visibility = "visible";')
driver.execute_script('document.getElementById("gwt-debug-column-SEARCH_VOLUME_PRIMARY-header-0-0").style.display = "block";')
searches = driver.find_element_by_xpath("//*[contains(text(), 'Avg. monthly searches')]")
if searches.is_displayed():
    print "searches is visible"
else:
    print "searches isn't visible"
avg_monthly_searches = driver.find_elements_by_id("gwt-debug-column-SEARCH_VOLUME_PRIMARY-header-0-0") 
for avg in avg_monthly_searches:
    if avg.is_displayed():
        print "element is visible, so clicking ..."
        actions = ActionChains(driver)
        actions.click(on_element=avg).perform()
        time.sleep(10)
        print "scrolling to the bottom"
        driver.execute_script("window.scrollTo(0, document.body.scrollHeight);")
        print "getting the page source as interpreted by chromedriver"
        driver.execute_script('return document.documentElement.innerHTML')
        print "getting keyword ideas source"
        content = driver.page_source
        with open('keyword_ideas.html', 'w') as f:
            f.write(content.encode('utf-8'))    
            time.sleep(5)
            print "getting html"
            dom = DOM(content)
            print "traversing ... "
            for e in dom('td.spgb-f'):
                for a in e('a.sptc-e.sptc-h'):
                    print repr(plaintext(a.content))           
    else:
        print "element isn't visible"

请尝试以下代码：

driver.execute_script('document.getElementById("gwt-debug-column-SEARCH_VOLUME_PRIMARY-header-0-0").style.visibility = "visible";')
driver.execute_script('document.getElementById("gwt-debug-column-SEARCH_VOLUME_PRIMARY-header-0-0").style.display = "block";')
