Selenium 有时不单击复选框

Question

我是 Selenium 的新手，所以我正在制作一个机器人来自动完成琐事，这样我就可以理解这个模块，这是一个很好的做法。有时 .click() 函数不起作用。

我试过了：

• 使用 JavaScript 点击
• 使用 WebDriverWait
• 退出并关闭驱动并重新打开页面
• 继续点击，直到复选框 ID 有效（继续循环）
• 刷新页面并尝试再次单击（Java 和普通 .click()
• 改用 time.sleep(time) 等待
• 根本不使用 webdriver 等待，只是设置 var

我以前确实有过时的元素错误，但我已经解决了。

注意：它大部分时间都会点击，但随机只是不起作用，不是错误或任何东西

进口：

from selenium import webdriver
from time import *
from data import *
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.common.exceptions import NoSuchElementException, StaleElementReferenceException
from winsound import *
import os

部分代码：

我已经看到了一些以前的答案，它们与已解决的过时元素错误有关。我相信这是一个不同的问题。

Answer 1

非常抱歉。我专注于我的代码而不是其他任何事情，我没有注意到它总是在“化学元素琐事”上失败。我也没有注意到它总是在一个问题上失败；这是因为我忘记在 data.py 字典问题中输入一个单词。现在一切正常。

感谢大家的帮助。我再次道歉

我现在感觉很愚蠢：/

Answer 2

另外三个想法：

1. 流畅的等待：

   Wait<WebDriver> fluentWait = new FluentWait<>(driver) .withTimeout(30, TimeUnit.SECONDS) .pollingEvery(300, TimeUnit.MILLISECONDS) .ignoring(NoSuchElementException.class) .ignoring(StaleElementReferenceException.class);

   public WebElement fluentWait(By by) { WebElement waitElement = null; try { waitElement = fluentWait.until(webDriver -> getDriver().findElement(by)); } catch (TimeoutException ex) {} return waitElement; }

2. 使用动作类

   WebElement element = fluentWait(by); Actions actions = new Actions(getDriver()); actions.moveToElement(element); actions.click(); actions.build().perform();

3. 找出您应该等待的事件。应用程序是用 Angular 编写的吗？反应？ jQuery？
