python輸入無法定位,Selenium無法定位元素（Python）

I'm trying to scrape a real estate website for listings. It has an aspx form that has to filled out before submission.

All I care about is multifamily properties in Oregon, however. So this was my first attempt:

driver = webdriver.Firefox()

driver.get("http://www.cbre.us/PropertyListings/Pages/Properties-for-Sale.aspx")

#Searching for multifamily residences

selectPropertyType = driver.find_element_by_id("ForSalePropertyType")

selectPropertyType.select_by_value("70")

#In the state of Oregon

selectState = driver.find_element_by_id("ForSaleState_ListBox1")

selectState.select_by_value("OR")

#Submit form

submitBtn = driver.find_element_by_id("ForSaleLooplinkSubmit")

submitBtn.click()

#Wait for results to load

WebDriverWait(driver, 5)

When I run this script it gives an error "Can't locate element "ForSalePropertyType". What am I doing wrong here? Thanks in advance.

This element located inside an iframe. You have to switch to it's context:

driver.switch_to.frame("ctl00_PlaceHolderMain_IFrameContent_IFrameContent")

# searching for multifamily residences

selectPropertyType = driver.find_element_by_id("ForSalePropertyType")

selectPropertyType.select_by_value("70")

To get back to default context:

driver.switch_to.default_content()
