问题
I'm trying to learn the Python version of Playwright. See here
I would like to learn how to locate an element, so that I can do things with it. Like printing the inner HTML, clicking on it and such.
The example below loads a page and prints the HTML
from playwright import sync_playwright
with sync_playwright() as p:
browser = p.chromium.launch(headless=False)
page = browser.newPage()
page.goto('http://whatsmyuseragent.org/')
print(page.innerHTML("*"))
browser.close()
This page contains an element
<div class="user-agent">
<p class="intro-text">Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/86.0.4238.0 Safari/537.36</p>
</div>
Using Selenium, I could locate the element and print it's content like this
elem = driver.find_element_by_class_name("user-agent")
print(elem)
print(elem.get_attribute("innerHTML"))
How can I do the same in Playwright?
回答1:
You can use the querySelector
function, and then call the innerHTML
function:
handle = page.querySelector(".user-agent")
print(handle.innerHTML())
