使用Selenium无法设置Input元素值的技术问题求助

在Windows 10系统上使用Edge浏览器，通过Python和Selenium WebDriver尝试更新Input元素的值。页面加载正常，可通过键盘和鼠标与该元素交互，但通过代码设置值时出现“element not interactable”错误。

from selenium import webdriver
from selenium.webdriver.common.by import By
import time

edge_service = webdriver.EdgeService(executable_path=edge_driver_path)
edge_driver = webdriver.Edge(service=edge_service)
edge_driver.get(url)
time.sleep(15)
elements, macroponent_bs = edge_driver.find_elements(by=By.XPATH, value="//*"), None
for element in elements:
    if element.tag_name.startswith("macroponent"):
        macroponent_bs = element.tag_name
        break
if macroponent_bs:
    script = "return document.querySelector('" + macroponent_bs + "')" + \
             ".shadowRoot.querySelector('iframe')"
    iframe = edge_driver.execute_script(script=script)
    edge_driver.switch_to.frame(iframe)
element = edge_driver.find_element(by=By.ID, value=element_id)
print(f"Element value is >{element.get_attribute('value')}<")
print(f"Element is_enabled, is_displayed = {element.is_enabled()}, {element.is_displayed()}")
element.send_keys("Hello")

• 强制滚动到元素可见位置
  元素is_displayed()返回False但手动可交互，大概率是元素处于视口外。用JavaScript将元素滚动到视口中央：

  edge_driver.execute_script("arguments[0].scrollIntoView({block: 'center'});", element)
  

• 直接用JavaScript设置元素值
  绕开Selenium的交互检查，直接修改Input元素的value属性：

  edge_driver.execute_script("arguments[0].value = 'Hello';", element)
  

• 替换固定等待为显式等待
  去掉time.sleep(15)，改用显式等待确保元素真正可交互：

  from selenium.webdriver.support.ui import WebDriverWait
  from selenium.webdriver.support import expected_conditions as EC
  
  # 切换到iframe后等待元素可点击/交互
  element = WebDriverWait(edge_driver, 20).until(
      EC.element_to_be_clickable((By.ID, element_id))
  )
  

• 检查元素是否被遮挡
  页面可能存在透明层、弹窗等遮挡元素，用JavaScript验证：

  is_obscured = edge_driver.execute_script("""
      var element = arguments[0];
      var rect = element.getBoundingClientRect();
      var centerPoint = {x: rect.left + rect.width/2, y: rect.top + rect.height/2};
      var topElement = document.elementFromPoint(centerPoint.x, centerPoint.y);
      return topElement !== element && !element.contains(topElement);
  """, element)
  if is_obscured:
      # 处理遮挡元素，比如关闭弹窗、隐藏遮罩层
      pass
