如何使用python在新页面重新加载后点击链接？

Question

基本上，我想自动化谷歌搜索引擎，基本上搜索和点击第一个链接，搜索按钮被点击后填充，所以我用python做这件事。我能够成功地搜索内容，但无法在重新加载页面后单击链接

from selenium import webdriver
from selenium.webdriver.common.action_chains import ActionChains

url = "https://www.google.com"
driver = webdriver.Chrome("C:/Users/User/Python/AllCodes/chromedriver.exe")

driver.get(url)
insert = driver.find_element_by_name("q")
insert.send_keys("K.J.Somaiya")
button = driver.find_element_by_name("btnK")
button.submit()
# after this new page reload and link are poluated

linktext = driver.find_element_by_link_text("K. J. Somaiya Institute of Management")
linktext.submit()

这个输入类我用的名字是q

<input class="gLFyf gsfi" jsaction="paste:puy29d;" maxlength="2048" name="q" type="text" aria-autocomplete="both" aria-haspopup="false" autocapitalize="off" autocomplete="off" autocorrect="off" autofocus="" role="combobox" spellcheck="false" title="Search" value="" aria-label="Search" data-ved="0ahUKEwj9qOfEmLzvAhWSj-YKHZUYDngQ39UDCAQ">

这是我的目标链接文本中的html代码，它是K.J.Somaiya Inst。。。。。

您需要等待该元素在dom中变为可见。在这里阅读有关selenium的文章

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

url = "https://www.google.com"
driver = webdriver.Chrome("C:/Users/User/Python/AllCodes/chromedriver.exe")

driver.get(url)
insert = driver.find_element_by_name("q")
insert.send_keys("K.J.Somaiya")
button = driver.find_element_by_name("btnK")
button.submit()
# after this new page reload and link are poluated
linktext = WebDriverWait(driver, 10).until(
        EC.presence_of_element_located((By.PARTIAL_LINK_TEXT, "K. J. Somaiya"))
    ) # Waits 10 second before element loads.

linktext.click()
