selenium中的隐式等待

发布于 28 分钟前
from selenium import webdriver
  self.driver = webdriver.Chrome()
  self.driver.implicitly_wait(10)
  self.driver.maximize_window()
  self.driver.get("https://magento.com/products/magento-open-source")

1.由于网络延时或者动态加载元素导致页面无法短时间显示，使用隐式等待是很有效的解决办法。隐式等待的默认时间是0s，本例中，设置等待时间为10s，这10s并非固定的等待时间，而是如果在第5s中搜到DOM元素，则接着往下执行，如果10s后还没定位到元素，那么抛出NoSuchElementException异常。
2.一旦设置隐式等待，将作用于WebDriver实例的整个生命周期。
