python - Selenium 蟒 : How to wait for a page to load after a click?

Question

我想在点击后抓取页面的页面源。然后使用 browser.back() 函数返回。但是 Selenium 不会让页面在点击后完全加载，并且由 JavaScript 生成的内容不会包含在该页面的页面源中。

element[i].click()
#Need to wait here until the content is fully generated by JS.
#And then grab the page source.
scoreCardHTML  = browser.page_source
browser.back()

Answer 1

正如 Alan 提到的 - 您可以等待加载某些元素。下面是示例代码

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

browser = webdriver.Firefox()
element = WebDriverWait(browser, 10).until(EC.presence_of_element_located((By.ID, "element_id")))
