Unable to find element and input value using selenium

Question

My objective is to take a value (in my case a shipment tracking #) and input it into a tracking field on a website using selenium. I am unable to input the value and get the following error message:

from selenium import webdriver
from selenium.webdriver.common.keys import Keys

chromedriver = "/Users/GUVA/Downloads/chromedriver"
driver = webdriver.Chrome(chromedriver)
driver.get("https://www.17track.net/en")

#data = df.values[1] # grabbing one tracking number from an excel file

# click "agree" to close window
python_button = driver.find_elements_by_xpath('//*[@id="modal-gdpr"]/div/div/div[3]/button')[0]
python_button.click()

# enter tracking number into text box
que=driver.find_element_by_id('//input[@id="jsTrackBox"]')
que.send_keys("data")

Traceback (most recent call last):
File "/Users/GUVA/PycharmProjects/Shipment_Tracking/Track Shipment.py", line 26, in <module>
que=driver.find_element_by_id('//input[@id="jsTrackBox"]')

raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.InvalidSelectorException: Message: invalid selector: An invalid or illegal selector was specified

Any suggestions please?

Answer 1

//input[@id="jsTrackBox"] is an xpath. So you need to fetch the element by using find_element_by_xpath method(where you are currently using find_element_by_id method).

Your code should be like:

from selenium import webdriver
from selenium.webdriver.common.keys import Keys

chromedriver = "/Users/GUVA/Downloads/chromedriver"
driver = webdriver.Chrome(chromedriver)
driver.get("https://www.17track.net/en")

#data = df.values[1] # grabbing one tracking number from an excel file

# click "agree" to close window
python_button = driver.find_elements_by_xpath('//*[@id="modal-gdpr"]/div/div/div[3]/button')[0]
python_button.click()

# enter tracking number into text box
que=driver.find_element_by_xpath("//div[@id='jsTrackBox']//div[@class='CodeMirror-scroll']")
que.click()
que.send_keys("data")
