使用 selenium 和 python 处理模态

Answer 1

绝对xpath，例如：

/html/body/div[4]

和

/html/body/div[5]

具有从根到我们想要识别的元素的完整路径，总是很脆弱，就像从根到元素的属性发生任何变化一样，我们的绝对xpath将变得无效。

解决方案

您可以使用逻辑 xpath，而不是绝对 xpath，如下所示：

br.find_element(By.XPATH, "//div[@id='footer']/div[@class='modal_list pleaseWait_container']")
print(thread, "found modal list please wait container")
sleep(5)
br.find_element(By.XPATH, "//div[@id='footer']/div[@class='ui-dialog ui-widget ui-widget-content ui-corner-all ui-front newpropushbelowmenu ui-dialog-buttons']")
print(thread, "line after modal list please wait container")

---

此外，由于元素位于 Modal 内，理想情况下您需要为 presence_of_element_ located() 引入 WebDriverWait 并且您可以使用以下 定位器策略:

WebDriverWait(br, 20).until(EC.presence_of_element_located((By.XPATH, "//div[@id='footer']/div[@class='modal_list pleaseWait_container']")))
print(thread, "found modal list please wait container")
WebDriverWait(br, 20).until(EC.presence_of_element_located((By.XPATH, "//div[@id='footer']/div[@class='ui-dialog ui-widget ui-widget-content ui-corner-all ui-front newpropushbelowmenu ui-dialog-buttons']")))
print(thread, "line after modal list please wait container")

• 注意：您必须添加以下导入：

  from selenium.webdriver.support.ui import WebDriverWait
  from selenium.webdriver.common.by import By
  from selenium.webdriver.support import expected_conditions as EC
