WebDriver' object has no attribute 'switch_to_frame'

Question

I cannot switch to the sucessfully identified iFrame(s). The script identifies the iFrame (checked in debugger), but the switch to the iFrame fails and runs into the exception trap. Few times ago it worked perfectly.

Message='WebDriver' object has no attribute 'switch_to_frame'

What happened in the meantime?

Chromedriver has been updated from version 95.0.4638.17 to ChromeDriver 96.0.4664.45

Is the Chromedriver is no longer compatible with the latest Selenium version?

... 
driver.switch_to.default_content()

try:
    # find the frame
    wait.until(EC.element_to_be_clickable((By.ID, "wysiwygTextarea_ifr")))
    frame2 = driver.find_element(By.XPATH, "//iframe[@id='wysiwygTextarea_ifr']");
    
    # switch to frame
    driver.switch_to.frame(frame2.tag_name);

    print("--------------iframe found-------------------"); 
except:
    print("--------------iframe not found-------------------");

Answer 1

切换到frame时，支持的符号是：

• 使用框架名称切换到框架：

  driver.switch_to.frame('frame_name')
  

• 使用帧索引切换到帧：

  driver.switch_to.frame(1)
  

• 使用框架元素切换到框架：

  driver.switch_to.frame(driver.find_elements_by_tag_name("iframe")[0])
  

• • 切换到父框架：

    driver.switch_to.parent_frame()

• 切换到默认内容：

  driver.switch_to.default_content()
  

这个用例

要切换您使用的框架：

driver.switch_to.frame(frame2.tag_name);

也就是说，TAG_NAME不受支持。因此你会看到错误：

Message='WebDriver' object has no attribute 'switch_to_frame'

解决方案

您可以使用以下代码行：

# find the frame
wait.until(EC.element_to_be_clickable((By.ID, "wysiwygTextarea_ifr")))
frame2 = driver.find_element(By.XPATH, "//iframe[@id='wysiwygTextarea_ifr']");
    
# switch to frame by frame element
driver.switch_to.frame(frame2);
