# Dom Traversal
这个例子演示了如何在Python中遍历DOM。
import webview
def bind(window):
container = window.dom.get_element('#container')
container_button = window.dom.get_element('#container-button')
blue_rectangle = window.dom.get_element('#blue-rectangle')
blue_parent_button = window.dom.get_element('#blue-parent-button')
blue_next_button = window.dom.get_element('#blue-next-button')
blue_previous_button = window.dom.get_element('#blue-previous-button')
container_button.events.click += lambda e: print(container.children)
blue_parent_button.events.click += lambda e: print(blue_rectangle.parent)
blue_next_button.events.click += lambda e: print(blue_rectangle.next)
blue_previous_button.events.click += lambda e: print(blue_rectangle.previous)
