Unable to find element using Selenium-CodePudding

Using Selenium, I am unable to locate the "email" element on the Udemy website.

Here's what I tried:

browser.get('https://www.udemy.com/join/login-popup/')
browser.implicitly_wait(5)

email = browser.find_element(By.ID, 'email--1')
print(email)

but it gives NoSuchElementException while "email" element isn't even in an iframe, as far as I know.

So, how can I locate this specific element?

CodePudding user response：

In this case, you're probably looking for the element before the page loads.

You should use the WebDriverWait class of Selenium and the condition presence_of_element_located of the expected_conditions, as shown in the example below:

from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.support.wait import WebDriverWait


browser.get('https://www.udemy.com/join/login-popup/')
timeout = 20  # Number of seconds before timing out.
email = WebDriverWait(browser, timeout).until(EC.presence_of_element_located((By.ID, 'email--1')))
email.send_keys("[email protected]")

In the above snippet, Selenium WebDriver waits up to 20 seconds before throwing a TimeoutException, unless it finds the element to return within the above time. WebDriverWait, by default, calls the ExpectedCondition every 500 milliseconds until it returns successfully.

Finally, presence_of_element_located is an expectation for determining whether an element is present on a page's DOM, without necessarily implying that the element is visible. When the element is found, the locator returns the WebElement.
