无法使用Selenium向文本框发送键。出现selenium.common.exceptions.TimeoutException: 消息:

Question

我正在尝试使用Selenium给搜索框输入内容，但遇到了错误：

Traceback (most recent call last):

    WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "input#typeahead-input-56352"))).send_keys("2216 NW 6 PL FORT LAUDERDALE")

这是我用来输入内容的代码：

# Import Dependencies
from bs4 import BeautifulSoup as bs
from selenium import webdriver
from selenium.webdriver.support.ui import Select
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.webdriver.common.action_chains import ActionChains
import time

options = webdriver.ChromeOptions()
options.headless = True

driver = webdriver.Chrome()
driver.maximize_window()

driver.get("https://broward.county-taxes.com/public/search/property_tax")
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, '//*[@class="svg-icon"]'))).click()
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "input#typeahead-input-56352"))).send_keys("2216 NW 6 PL FORT LAUDERDALE")
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, '//*[@id="search-icon"]/svg'))).click()

在输入内容之前，我甚至还关闭了一个弹窗。我试过用 XPATH 和 CSS_SELECTOR，但都出现了同样的错误。

请帮帮我。

Answer 1

问题的根本原因： ID 属性的值是动态的。所以，像 input#typeahead-input-56352 这样的写法是行不通的。每次页面加载时，数字（56352）都会变化。

解决方案： 你可以改用 XPath 定位策略，XPath 表达式可以写成： //input[@role='searchbox']

把下面这一行改成：

WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "input#typeahead-input-56352"))).send_keys("2216 NW 6 PL FORT LAUDERDALE")

改成：

WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//input[@role='searchbox']"))).send_keys("2216 NW 6 PL FORT LAUDERDALE")

注意： 另外，在下面这一行，XPath 表达式 //*[@id="search-icon"]/svg 是不正确的，它没有找到任何元素。我已经在下面的有效代码中修正了它。

请查看下面重构后的有效代码：

driver = webdriver.Chrome()
driver.maximize_window()
wait = WebDriverWait(driver, 20)

driver.get("https://broward.county-taxes.com/public/search/property_tax")
wait.until(EC.element_to_be_clickable((By.XPATH, '//*[@class="svg-icon"]'))).click()
wait.until(EC.element_to_be_clickable((By.XPATH, '//input[@role="searchbox"]'))).send_keys("2216 NW 6 PL FORT LAUDERDALE")
wait.until(EC.element_to_be_clickable((By.XPATH, '//span[@id="search-icon"]'))).click()
