示例1: ensure_element
# 需要导入模块: from selenium.webdriver.support.ui import WebDriverWait [as 别名]
# 或者: from selenium.webdriver.support.ui.WebDriverWait import ensure_click [as 别名]
def ensure_element(self, locator, selector, state="present", timeout=None):
"""This method allows us to wait till an element appears or disappears in the browser
The webdriver runs in parallel with our scripts, so we must wait for it everytime it
runs javascript. Selenium automatically waits till a page loads when GETing it,
but it doesn't do this when it runs javascript and makes AJAX requests.
So we must explicitly wait in that case.
The 'locator' argument defines what strategy we use to search for the element.
The 'state' argument allows us to chose between waiting for the element to be visible,
clickable, present, or invisible. Presence is more inclusive, but sometimes we want to
know if the element is visible. Careful, its not always intuitive what Selenium considers
to be a visible element. We can also wait for it to be clickable, although this method
is a bit buggy in selenium, an element can be 'clickable' according to selenium and
still fail when we try to click it.
