python selenium：<input> 元素不可交互答案

【问题标题】：python selenium: <input> element not interactablepython selenium：<input> 元素不可交互
【发布时间】：2021-02-25 03:02:00
【问题描述】：

我试图从https://nba.com/players 抓取 nba 球员信息，然后点击网页上的“显示历史”按钮 nba_webpage_picture

输入按钮的部分html代码如下所示：

<div aria-label="Show Historic Toggle" class="Toggle_switch__2e_90">
    <input type="checkbox" class="Toggle_input__gIiFd" name="showHistoric">
    <span class="Toggle_slider__hCMQQ Toggle_sliderActive__15Jrf Toggle_slidercerulean__1UnnV">
    </span>
</div>

我只是使用find_element_by_xpath定位输入按钮并点击

button_show_historic = driver.find_element_by_xpath("//input[@name='showHistoric']")
button_show_historic.click()

但是它说：

Exception has occurred: ElementNotInteractableException
Message: element not interactable
  (Session info: chrome=88.0.4324.192)

有人可以帮忙解决这个问题吗？这是因为输入不可见吗？

【问题讨论】：

你想做什么？有一种更简单的方法可以在不使用硒的情况下做到这一点
我的元素是under a shadow root and I also had to use a CSS selector。

【解决方案1】：

只需等待 span 元素而不是 input 元素并点击。

wait = WebDriverWait(driver, 30)
driver.get('https://www.nba.com/players')
wait.until(EC.element_to_be_clickable((By.XPATH,"//button[.='I Accept']"))).click()
wait.until(EC.element_to_be_clickable((By.XPATH,"//input[@name='showHistoric']/preceding::span[1]"))).click()

导入

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

也可以在开发者工具->网络->标题下找到一个api 并响应以查找它是否被填充。

【讨论】：

感谢您的分享。这行得通！但是我现在想知道为什么我们必须输入/preceding::span[1]" 才能完成这项工作？
切换滑块在跨度而不是输入上激活。
如果有帮助，请接受我的回答。

【解决方案2】：

最可能的问题是您没有任何等待代码。您应该等到页面加载完毕。您可以使用简单的 python 睡眠功能：

import time 
time.sleep(3) #it will wait 3 seconds
##Do your action

或者您可以使用显式等待。查看此页面：selenium.dev

【解决方案3】：

有 api 时无需使用 selenium。试试这个：

import requests
import pandas as pd


url = 'https://stats.nba.com/stats/playerindex'
headers = {'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/88.0.4324.150 Safari/537.36',
'Referer': 'http://stats.nba.com'}

payload = {
'College': '',
'Country': '',
'DraftPick': '',
'DraftRound': '',
'DraftYear': '',
'Height': '' ,
'Historical': '1',
'LeagueID': '00',
'Season': '2020-21',
'SeasonType': 'Regular Season',
'TeamID': '0',
'Weight': ''}
    
jsonData = requests.get(url, headers=headers, params=payload).json()
cols = jsonData['resultSets'][0]['headers']
data = jsonData['resultSets'][0]['rowSet']
df = pd.DataFrame(data, columns=cols)

输出：[4589 行 x 26 列]

print(df.head(20).to_string())

这将是一个愚蠢的问题：我们如何知道是否有 api？我们如何知道使用 api 的正确格式/参数？
@Sean Hsieh 看看我的回答
你必须查看 Dev Tools 并查看 Network -> XHR。然后只需在那里搜索，看看你所追求的数据是否在某个地方。除了简单地调查/窥探并查看是否被请求之外，没有确定的方法可以做到这一点
