atom 1.54 无法从浏览器获取 xpath（带有 Firefox 的 selenium webdriver）

Question

这是我的代码：

from selenium import webdriver
from selenium.webdriver.common.action_chains import ActionChains
from selenium.webdriver.support.ui import WebDriverWait

browser = webdriver.Firefox()
browser.get('https://pbx.voxbaysolutions.com/#/page/signin')

browser.find_element_by_xpath('//input[@ng-model="user.name"]').send_keys('thj')

这里是错误：

Traceback (most recent call last):

    raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.NoSuchElementException: Message: Unable to locate element: //input[@ng-model="user.name"]

正在获取元素

<input type="text" name="name" ng-model="user.name" class="form-control ng-pristine ng-invalid ng-invalid-required ng-touched" placeholder="User email" required="" tabindex="0" aria-required="true" aria-invalid="true">

Answer 1

在发送密钥之前等待网络元素加载：

WebDriverWait(browser, 30).until(EC.visibility_of_element_located((By.XPATH, '//input[@ng-model="user.name"]'))).send_keys('thj')

需要这些导入：

from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By

Answer 2

要将 字符序列 发送到 <input> 元素，您可以使用以下任一方法 :

使用CSS_SELECTOR:

driver.find_element(By.CSS_SELECTOR, "a[name='name'][ng-model='user.name']").send_keys('thj')

使用XPATH:

driver.find_element(By.XPATH, "//a[@name='name' and @ng-model='user.name']").send_keys('thj')

但是所需的元素是 Angular 元素，因此要将 字符序列 发送到您需要的元素为引入 WebDriverWait 并且您可以使用以下任一项 :

使用CSS_SELECTOR:

WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "a[name='name'][ng-model='user.name']"))).send_keys('thj')

使用XPATH:

WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//a[@name='name' and @ng-model='user.name']"))).send_keys('thj')

注意：您必须添加以下导入：

from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
