单击具有 href 属性的链接<li>

Question

我试图点击登录链接，但系统抛出noSuchElementException。我也尝试过xpath，但我无法点击登录按钮，我正在附加代码

from selenium import webdriver
from selenium.webdriver.common.by import By
import time
class CreateAccount:
def signUp(self):
    browser = webdriver.Firefox()
    browser.get("http://www.scrumdo.com")
    time.sleep(5)
    browser.find_element_by_link_text("Login").click()
    time.sleep(5)
    browser.find_element_by_xpath("//a[@href='/account/signup']").click()
    time.sleep(5)
    browser.find_element_by_xpath("//input[@name='username']").send_keys("Rockyhandsome")
    browser.find_element_by_xpath("//input[@name='fullname']").send_keys("Naqash Zafar")
    browser.find_element_by_xpath("//input[@name='email']").send_keys("[e-mail]")
    browser.find_element_by_xpath("//input[@name='password']").send_keys("k12345678")
    browser.find_element_by_xpath("//button[@type='submit']").click()
CA = CreateAccount()
CA.signUp()

您需要单击下拉菜单，然后选择登录按钮：

class CreateAccount:
    def signUp(self):
        browser = webdriver.Firefox()
        browser.get("http://www.scrumdo.com")
        menu = browser.find_element_by_xpath("//button[@class='navbar-toggle']")
        menu.click()
        time.sleep(.25)
        menu.find_element_by_xpath("//li/a[@mixpanel='Homepage Clicked Login']").click()
        browser.find_element_by_xpath("//a[@href='/account/signup']").click()
        time.sleep(.25)
        browser.find_element_by_xpath("//input[@name='username']").send_keys("Rockyhandsome")
        browser.find_element_by_xpath("//input[@name='fullname']").send_keys("Naqash Zafar")
        browser.find_element_by_xpath("//input[@name='email']").send_keys("[e-mail]")
        browser.find_element_by_xpath("//input[@name='password']").send_keys("k12345678")
        browser.find_element_by_xpath("//button[@type='submit']").click()

页面包含一些需要与服务生同步的动态内容。此外，您需要设置窗口的大小，因为布局类型可能会根据宽度而变化：

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.common.exceptions import WebDriverException
browser = webdriver.Firefox()
wait = WebDriverWait(browser, 20)
browser.set_window_size(1280, 768)
browser.get("http://www.scrumdo.com")
# click login
wait.until(EC.element_to_be_clickable((By.XPATH, "//a[.='Login']"))).click()
# wait for the login button
wait.until(EC.presence_of_element_located((By.ID, "loginButton")))
# click signup
browser.find_element_by_css_selector("a[href='/account/signup']").click()
# wait for the signup form
wait.until(EC.presence_of_element_located((By.ID, "signupForm")))
# fill the form
browser.find_element_by_css_selector("input[name=username]").send_keys("name")
browser.find_element_by_css_selector("input[name=fullname]").send_keys("password")
browser.find_element_by_css_selector("input[name=email]").send_keys("[e-mail]")
browser.find_element_by_css_selector("input[name=password]").send_keys("na")
browser.find_element_by_css_selector("button[type=submit]").click()
