I have edited this code thanks to the lovely comment below but I get the same error saying as below.:
Message: stale element reference: element is not attached to the page document
I roughly understand why this message shows up but still have no clear idea on how to fix this. I would deeply appreciate any comment! Many thanks in advance!
回答1:
This is what I figured out. But I'm not sure if code is right or not. I don't know python.
#get select
select1 = Select(driver.find_element_by_xpath('//select[@name="sido"]'))
#get all options from select
options1 = select1.options
for opt1 is options1:
#select the option which has the value of opt1
select1.select_by_value(opt1.get_attribute("value"))
time.sleep(5)
select2 = Select(driver.find_element_by_xpath('//select[@name="gugu"]'))
options2 = select2.options
for opt2 in options2:
select1.select_by_value(opt2.get_attribute("value"))
time.sleep(4)

To select all the <option>
elements from multiple e.g. two (2) different drop-down-select elements within the website https://price.joinsland.joins.com/theme/index_theme.asp?sisaegbn=T05 you need to induce WebDriverWait for the element_to_be_clickable()
and you can use the following xpath based Locator Strategies:
driver.get('https://price.joinsland.joins.com/theme/index_theme.asp?sisaegbn=T05')
select1 = Select(WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//select[@name='sido']"))))
for item1 in select1.options:
item1.click()
select2 = Select(WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//select[@name='gugun']"))))
for item2 in select2.options:
item2.click()
time.sleep(3) # perform your web-crawling here
