python, selenium中用于切换帧的函数

问题描述

我正在寻找一种可以更轻松地在两个帧之间切换的功能.现在，每次我需要在帧之间切换时，我都通过以下代码来做到这一点:

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，该函数接受一个参数来更改导航或内容，因为其余部分基本相同.

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)]
                  ^

SyntaxError: 无效语法

SyntaxError: invalid syntax

推荐答案

这个写法，它试图将 CSS 代码解析为 Python 代码.你不想这样.

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()
