Question

<img src="images/file_explorer.png" class="browse" style="cursor: pointer;height:33px;" title="file from your computer">

from selenium import webdriver
from selenium.webdriver.chrome.webdriver import WebDriver
from selenium.webdriver.common.keys import Keys

import time

driver = webdriver.Chrome(executable_path="C:/webdrivers/chromedriver.exe")
driver.maximize_window()
driver.get("https://www.collabera.com/find-a-job/search-jobs/?sort_by=dateposted&Posteddays=4000&searchany=QA&anylocation=usa")
time.sleep(3)
driver.find_element_by_css_selector("#srchpgbnnr > div:nth-child(1) > div:nth-child(1) > div > a").click()

driver.find_element_by_css_selector("body > section:nth-child(7) > div:nth-child(2) > div > div.col-md-offset-2.col-md-3.__jobdesc-sidebar.col-xs-hide > div > a").click()
time.sleep(15)
driver.find_element_by_css_selector("img.browse[src='images/file_explorer.png'][title='file from yourcomputer']").send_keys("C:\\Users\\user\\Desktop\\collebra.txt")

我的代码高于一个它不起作用 如何在上面的上传按钮代码中找到元素

Answer 1

1. 为了能够处理文件上传表单，您需要切换到 iframe：

   driver.switch_to.frame(driver.find_element_by_class_name("apply-form"))
   

2. 你需要处理input元素，而不是img：

   driver.find_element_by_xpath("//input[@type='file']").send_keys("C:\\Users\\user\\Desktop\\collebra.txt")
   

Answer 2

要查找元素并调用 send_keys() 方法，您可以丢弃 time.sleep(5) 并诱导 WebDriverWait 并使用以下任何选项：

• CSS_SELECTOR：

  WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "img.browse[src='images/file_explorer.png'][title='file from your computer']"))).send_keys("C:\\Users\\user\\Desktop\\collebra.txt")
  

• XPATH：

  WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//img[@class='browse' and @src='images/file_explorer.png' and @title='file from your computer']"))).send_keys("C:\\Users\\user\\Desktop\\collebra.txt")
