WebDriver' object has no attribute 'switch_to

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-------------------");

...

CodePudding user response：

While switching to frame, the supported notations are:

Switch to a frame using frame name:
```
driver.switch_to.frame('frame_name')
```
Switch to a frame using frame index:
```
driver.switch_to.frame(1)
```

Switch to a frame using frame element:

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

- Switch to parent frame:
  
  driver.switch_to.parent_frame()
Switch to default content:
```
driver.switch_to.default_content()
```

This usecase

To switch the frame you have used:

driver.switch_to.frame(frame2.tag_name);

that is, the TAG_NAME which isn't supported. Hence you see the error:

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

Solution

You can use the following line of code:

# 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);
