如何在python3中使用Selenium和phantomjs等待网页截图之前？

Question

Would like to create an image of a webpage but must wait to allow it to fully load (inc. AJAX).

The wait time should be set by an hardcoded value rather than waiting on an element.

The following takes a screenshot with no wait:

from selenium import webdriver

driver=webdriver.PhantomJS()
driver.set_window_size(w,h)
driver.get('webpage_address')
driver.save_screenshot('/path/to/dir/foo.png')
driver.quit()

Based on some documentation :

from selenium import webdriver

driver=webdriver.PhantomJS()
driver.set_window_size(w,h)
driver.implicitly_wait(t)
driver.get('webpage_address')
driver.save_screenshot('/path/to/dir/foo.png')
driver.quit()

However, this does not output an image nor does it seem to be waiting.

Any help is much appreciated!

Answer 1

Try the following code:

driver.manage().timeouts().implicitlyWait(10,TimeUnit.SECONDS) ;
or
wait = WebDriverWait(browser, 10)

Here we are implicitly asking the code to waiting for 10 seconds

Answer 2

Perhaps waiting until an element is present on the given page, which would mean it's fully loaded (not in all cases) you can then proceed to take a screenshot :)

WebDriverWait(driver, 20).until(
EC.presence_of_element_located((By.ID, "myElement"))

driver.save_screenshot('/path/to/dir/foo.png')
