Question

我正试图通过在whatsapp上通过硒向哥哥发送重复短信来惹恼我。问题是，即使我告诉它，它也没有明确等待2秒：button=WebDriverWait(driver, 2).until(EC.element_to_be_clickable((By.CLASS_NAME, '_35EW6'))) 它向他发送消息一次，两次或三次，然后停止。

代码如下：

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By
driver=webdriver.Chrome("C:\setups\chromedriver\chromedriver.exe")

driver.get("https://web.whatsapp.com/")

name=input("Enter the name of person or group: ")
msg=input("Enter a message: ")
count=eval(input("How many times: "))

input("Wait for ENTER")

user=driver.find_element_by_xpath('//span[@title="{}"]'.format(name))
user.click()
msg_box=driver.find_element_by_class_name("_1Plpp")
for i in range(count):
    msg_box.send_keys(msg)
    msg_box.send_keys(Keys.RETURN)
    button=driver.find_element_by_class_name('_35EW6')
    # button.click()
    button=WebDriverWait(driver, 2).until(EC.element_to_be_clickable((By.CLASS_NAME, '_35EW6')))
    button.click()

结果如下：

Answer 1

我只是删除了 1. from selenium.webdriver.common.keys import Keys 2. msg_box.send_keys(Keys.RETURN) 3. button=driver.find_element_by_class_name('_35EW6') 而且有效。
