Switch frames with selenium and phantomJS

问题

I need to open the search windows on this page.

https://permits.losgatosca.gov/CitizenAccess/default.aspx

With firefox is working just fine, but when I try to do the same with phantomJS i got an error.

This is the code I'm using to open the search

BUTTON_id =  'ctl00_PlaceHolderMain_TabDataList_TabsDataList_ctl01_LinksDataList_ctl00_LinkItemUrl' #'//*[@id="ctl00_PlaceHolderMain_TabDataList_TabsDataList_ctl01_LinksDataList_ctl00_LinkItemUrl"]/span'
driver_1.switch_to_frame("ACAFrame")
button = driver_1.find_element_by_id(BUTTON_id)
button.click()

And this is the error I'm getting with phanthomJS:

Message: Error Message => 'Unable to switch to frame'

In this post it says that using:

driver.switchTo().frame(frame_index)
driver.switchTo().frame(frame_id)
driver.switchTo().frame(frame_object)

It solves the issue, but I don't know what to put in:

frame_index         
frame_id           
frame_object

This is what you should try:

• upgrade both selenium and PhantomJS to the latest versions

• add a wait before switching to frame:

  from selenium.webdriver.common.by import By
  from selenium.webdriver.support.ui import WebDriverWait
  from selenium.webdriver.support import expected_conditions as EC
  
  wait = WebDriverWait(driver, 10)
  wait.until(EC.presence_of_element_located((By.ID, "ACAFrame")))
  
  driver.switch_to.frame("ACAFrame")
  

(worked for me)
