如何用Selenium设置输入框值？日期输入send_keys无效求助

针对你遇到的日期输入框已选中但无法通过send_keys赋值的问题，可尝试以下几种方案：

• 移除readonly属性后输入
  多数网站的日期输入框会设置readonly属性限制手动输入，需先通过JavaScript移除该属性，再执行输入操作：

  from selenium import webdriver
  from selenium.webdriver.common.by import By
  from selenium.webdriver.support import expected_conditions as EC
  from selenium.webdriver.support.wait import WebDriverWait
  import time
  
  driver = webdriver.Chrome()
  driver.get("https://permits.mynevadacounty.com/CitizenAccess/Cap/CapHome.aspx?module=Building&TabName=Building")
  wait = WebDriverWait(driver, 20)
  wait.until(EC.visibility_of_element_located((By.CSS_SELECTOR, "img[src='/CitizenAccess/nc-horizontal.png']")))
  
  start_date = wait.until(EC.element_to_be_clickable((By.ID, "ctl00_PlaceHolderMain_generalSearchForm_txtGSStartDate")))
  # 移除readonly属性
  driver.execute_script("arguments[0].removeAttribute('readonly');", start_date)
  start_date.clear()
  start_date.send_keys('01/01/2023')
  
  time.sleep(10)
  driver.quit()
  

• 直接用JavaScript设置value值
  绕过send_keys，直接通过JS修改输入框的value属性，这种方式更直接可靠：

  from selenium import webdriver
  from selenium.webdriver.common.by import By
  from selenium.webdriver.support import expected_conditions as EC
  from selenium.webdriver.support.wait import WebDriverWait
  import time
  
  driver = webdriver.Chrome()
  driver.get("https://permits.mynevadacounty.com/CitizenAccess/Cap/CapHome.aspx?module=Building&TabName=Building")
  wait = WebDriverWait(driver, 20)
  wait.until(EC.visibility_of_element_located((By.CSS_SELECTOR, "img[src='/CitizenAccess/nc-horizontal.png']")))
  
  start_date = wait.until(EC.visibility_of_element_located((By.ID, "ctl00_PlaceHolderMain_generalSearchForm_txtGSStartDate")))
  # 直接设置value值
  driver.execute_script("arguments[0].value = '01/01/2023';", start_date)
  
  time.sleep(10)
  driver.quit()
  

• 模拟日期选择器点击（备选）
  如果上述方法均无效，可尝试唤起日期选择器并模拟点击选择目标日期（需根据页面实际元素调整选择器）：

  from selenium import webdriver
  from selenium.webdriver.common.by import By
  from selenium.webdriver.support import expected_conditions as EC
  from selenium.webdriver.support.wait import WebDriverWait
  from selenium.webdriver.support.ui import Select
  import time
  
  driver = webdriver.Chrome()
  driver.get("https://permits.mynevadacounty.com/CitizenAccess/Cap/CapHome.aspx?module=Building&TabName=Building")
  wait = WebDriverWait(driver, 20)
  wait.until(EC.visibility_of_element_located((By.CSS_SELECTOR, "img[src='/CitizenAccess/nc-horizontal.png']")))
  
  # 点击输入框唤起日期选择器
  start_date = wait.until(EC.element_to_be_clickable((By.ID, "ctl00_PlaceHolderMain_generalSearchForm_txtGSStartDate")))
  start_date.click()
  
  # 选择年份
  year_select = Select(wait.until(EC.element_to_be_clickable((By.CSS_SELECTOR, "select.ui-datepicker-year"))))
  year_select.select_by_value('2023')
  # 选择月份（0对应1月）
  month_select = Select(wait.until(EC.element_to_be_clickable((By.CSS_SELECTOR, "select.ui-datepicker-month"))))
  month_select.select_by_value('0')
  # 选择1号日期
  day_btn = wait.until(EC.element_to_be_clickable((By.XPATH, "//a[text()='1']")))
  day_btn.click()
  
  time.sleep(10)
  driver.quit()
  

注意事项 #

• 等待元素时优先使用EC.element_to_be_clickable，确保元素处于可交互状态
• 执行JS操作前，需确认元素已被正确定位
