Question

我正在尝试从网站下载数据，虽然该网站根据我的搜索提供服务，但导出到Excel因某些奇怪的原因无法正常运行。请提供您的建议。

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

driver = webdriver.Chrome("C:\Python27\Scripts\chromedriver.exe")
driver.get("https://etrakit.friscotexas.gov/Search/permit.aspx")

number_option = driver.find_element_by_id("cplMain_btnSearch")
number_option.click()

delay = 3 
try:
    WebDriverWait(driver, delay).until(EC.presence_of_element_located((By.ID,"cplMain_btnSearch")))
    print "Page is ready!"
except TimeoutException:
    print "Loading took too much time!"


search_button = driver.find_element_by_id("cplMain_btnExportToExcel")
search_button.click()

options.add_argument("download.default_directory=C:\Users\Maggie\Desktop\Files\R Files")
driver = webdriver.Chrome(chrome_options=options)

driver.close()

错误：

Page is ready!

学习者，这应该考虑你的问题。需要更改为EC.visibility，而选项代码段会在以后给你错误，所以也要检查出来。

from selenium.webdriver.chrome.options import Options

driver = webdriver.Chrome("C:\Python27\Scripts\chromedriver.exe")
driver.get("https://etrakit.friscotexas.gov/Search/permit.aspx")

number_option = driver.find_element_by_id("cplMain_btnSearch")
number_option.click()

delay = 3 
try:
    WebDriverWait(driver, delay).until(EC.visibility_of_element_located((By.ID,"cplMain_btnExportToExcel")))
    print "Page is ready!"
except TimeoutException:
    print "Loading took too much time!"


search_button = driver.find_element_by_id("cplMain_btnExportToExcel")
search_button.click()

options = webdriver.ChromeOptions()
options.add_argument("download.default_directory=C:\Users\Maggie\Desktop\Files\R Files")
driver = webdriver.Chrome(r"C:\Python27\Scripts\chromedriver.exe", chrome_options = options)
