硒查找元素，然后单击它

Question

我试图让Selenium单击“ View All Companies按钮，但是我不确定自己在做什么错。 它no element found返回no element found

HTML代码

<div class="screener-toggles">
  <div class="buttons">
    <span class="button selected" data-name="advanced-screener">Search by Screener<span data-name="advanced-screener" class="arrow selected"></span></span>
    <span class="button" data-name="alpha-factors">Search by Alpha Factors<span data-name="alpha-factors" class="arrow"></span></span>
    <span class="button" data-name="all-companies">View All Companies<span data-name="all-companies" class="arrow"></span></span>
  </div>
</div>

我写的python代码

element1 = driver.find_elements_by_class_name('View All Companies')
element1.click()
# I have tried all-companies instead of View All Companies as well. But still doesn't work

我应该不使用find_elements_by_class_name吗？

任何关于我做错事的建议都将不胜感激！

Answer 1

试试xpath ： "//span[contains(text(),'View All Companies')]"

Answer 2

是的，您不应使用find_elements_by_class_name而应使用find_element_by_class_name 。

当期望定位器返回多个元素时，将使用find_elements_by_class_name 。 对于特定元素，仅使用find_element_by_class_name 。

另一件事是，我无法在您的HTML代码中看到任何类名称为“ View All Companies 。 请查看您的HTML并仔细选择类名或其他定位符

希望对您有帮助

Answer 3

View All Companies是文字，不是课程。 尝试使用css_selector或xpath按文本css_selector

element1 = find_element_by_css_selector('span:contains("View All Companies")')

element1 = find_element_by_xpath('//span[contains(text(), "View All Companies")]')

或通过包含all-companies的data-name属性

element1 = find_element_by_css_selector('span[data-name*="all-companies"]')
