python、selenium中切换帧的函数 [英] function for switching frames in python, selenium
问题描述
我正在寻找一种可以更轻松地在两帧之间切换的功能.现在,每次我需要在帧之间切换时,我都是通过以下代码来实现的:
I'm looking for a function that makes it easier to switch between two frames. Right now, every time I need to switch between frames, I'm doing this by the following code:
driver.switch_to.frame(driver.find_element_by_css_selector("frame[name='nav']"))
driver.switch_to.frame(driver.find_element_by_css_selector("frame[name='content']"))
我的目标是获得一个函数,它接受一个参数来改变导航或内容,因为其余的基本相同.
My goal is to get a function that takes an argument just to change nav or content since the rest is basically the same.
我已经尝试过的是:
def frame_switch(content_or_nav):
x = str(frame[name=str(content_or_nav)] #"frame[name='content_or_nav']"
driver.switch_to.frame(driver.find_element_by_css_selector(x))
但它给了我一个错误
x = str(frame[name=str(content_or_nav)]
^
语法错误:无效语法
推荐答案
按照这种方式,它试图将 CSS 代码解析为 Python 代码.你不想那样.
The way this is written, it's trying to parse CSS code as Python code. You don't want that.
此功能适用:
def frame_switch(css_selector):
driver.switch_to.frame(driver.find_element_by_css_selector(css_selector))
如果你只是想根据 name
属性切换到框架,那么你可以使用这个:
If you are just trying to switch to the frame based on the name
attribute, then you can use this:
def frame_switch(name):
driver.switch_to.frame(driver.find_element_by_name(name))
要切换回主窗口,您可以使用
To switch back to the main window, you can use
driver.switch_to.default_content()
