Not able to detect the element and send input to the Credit Card Number field through Selenium

I'm trying to automate a checkout process on this website . I am at the 4th stage where you click the "Credit Card" option in "Payment Information" and I am trying to send_keys to input in my credit card numbers.

However, I notice that after clicking the CC option, the page loads for a bit so I used an explicit wait for that element but that is not working. Any help would be appreciated.

ccNumber = session.find_element_by_css_selector('input[name=credit-card-number]')
wait = WebDriverWait(session, 100)
wait.until(EC.element_to_be_selected(ccNumber))

This is the error:

selenium.common.exceptions.NoSuchElementException: Message: no such element: Unable to locate element: {"method":"css selector","selector":"input[name=credit-card-number]"}

The <input> field for the Credit Card number is within an <iframe> so you have to:

  • Induce WebDriverWait for the desired frame to be available and switch to it.
  • Induce WebDriverWait for the desired element to be clickable and you can use the following solution:

  • Code Block:

    WebDriverWait(session, 20).until(EC.frame_to_be_available_and_switch_to_it((By.ID,"braintree-hosted-field-number")))
WebDriverWait(session, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "input.number#credit-card-number"))).send_keys("0000000000000000")

You could wait until the Loading spinner no longer appears on the page anymore before checking for the credit card input. We have a C# solution that you could try to adapt to python where you wait in a loop for an element to be displayed, catching the exceptions until reaching the timeout. 

    //Assert an element is displayed before the timeout milliseconds run out.
    public void AssertElementIsDisplayed(int timeout, IWebElement element, string elementName = "element")
    {
        Action<IWebElement> target = delegate (IWebElement e) {
            if (e == null)
            {
                throw new AssertionException("Failed to find " + elementName + ". It is null");
            }
            if (!e.Displayed)
            {
                elementName = (elementName == "element" && !String.IsNullOrEmpty(e.GetAttribute("title"))) ? e.GetAttribute("title") : elementName;
                throw new AssertionException("Expected (" + elementName + ") to be displayed but it was not");
            }
        };
        AssertInLoop(element, (long)timeout, 100L, target);
    }

    //Assert some Action on a WebElement for as long as the timeoutMillis allow.
    private void AssertInLoop(IWebElement element, long timeoutMillis, long millisBetweenAttempts, Action<IWebElement> callable)
    {
        AssertionException lastAssertionError = null;
        WebDriverException lastWebDriverException = null;

        long startTime = DateTimeOffset.Now.Ticks / TimeSpan.TicksPerMillisecond;
        if (timeoutMillis < 500 || timeoutMillis > 120 * 1000)
        {
            throw new ArgumentException("Timeout outside expected range. timeout_millis=" + timeoutMillis);
        }

        long millisLeft = timeoutMillis;

        while (millisLeft >= 1)
        {
            long lastAttemptStartMillis = DateTimeOffset.Now.Ticks / TimeSpan.TicksPerMillisecond;
            try
            {
                callable(element);
                return;
            }
            catch (AssertionException e)
            {
                lastAssertionError = e;
                lastWebDriverException = null;
            }
            catch (StaleElementReferenceException e)
            {
                lastAssertionError = null;
                lastWebDriverException = e;
            }
            catch (NotFoundException e)
            {
                lastAssertionError = null;
                lastWebDriverException = e;
            }
            catch (SystemException e)
            {
                throw e;
            }


            long elapsedMillis = (DateTimeOffset.Now.Ticks / TimeSpan.TicksPerMillisecond) - startTime;
            millisLeft = timeoutMillis - elapsedMillis;

            if (millisLeft >= 1)
            {
                long millisElapsedDuringThisAttempt = (DateTimeOffset.Now.Ticks / TimeSpan.TicksPerMillisecond) - lastAttemptStartMillis;
                long millisToSleep = millisBetweenAttempts - millisElapsedDuringThisAttempt;
                if (millisToSleep > 0)
                {
                    Thread.Sleep((int)millisToSleep);
                }
            }
        }

        if (lastAssertionError != null)
        {
            throw lastAssertionError;
        }
        else if (lastWebDriverException != null)
        {
            throw lastWebDriverException;
        }
    }
