在Selenium中不再位于DOM之后切换回父帧 [英] Switching back to parent frame after it's no longer in DOM in Selenium
问题描述
我有以下页面
<body>
<iframe id="outer_frame">
<iframe id="search_button_frame">
<button id="search_button"></button>
</iframe>
</iframe>
</body>
现在点击 search_button 后两个框架outer_frame 和 search_button_frame 不再在DOM中，而是页面变得像这样
Now after I click on the search_button the two frames outer_frame and search_button_frame are no longer in DOM and instead the page becomes like this
<body>
<iframe id="form_frame">
...
</iframe>
</body>
我正在尝试去 search_button 然后将帧退出到主页面，然后使用以下方法切换到 form_frame ：
I'm trying to go to the search_button then get out of the frames into the main page, and then switching to the form_frame using this:
outer_frame = browser.find_element_by_xpath('//*[@id="outer_frame"]')
browser.switch_to.frame(outer_frame)
search_button_frame = browser.find_element_by_xpath('//*[@id="search_button_frame"]')
browser.switch_to.frame(search_button_frame)
search_button = browser.find_element_by_xpath('//*[@id="search_button"]')
search_button.click()
browser.switch_to_default_content()
form_frame = browser.find_element_by_xpath('//*[@id="form_frame"]')
browser.switch_to.frame(form_frame)
但是我一直收到以下错误：
but I keep getting the following error:
selenium.common.exceptions.NoSuchElementException: Message: no such element: Una
ble to locate element: {"method":"xpath","selector":"//*[@id="form_frame"]"}
这是否意味着我没有位于正确的框架中？
does this mean I'm not positioned in the right frame?
推荐答案
根据您的问题和 DOM树 结构点击 search_button 您需要先切换到 default_content（），然后切换到下一个所需的< iframe> 使用 WebDriverWait ，如下所示：
As per your question and the DOM Tree structure post clicking on the search_button you need to switch to the default_content() first and then switch to the next desired <iframe> using WebDriverWait as follows:
driver.switch_to.default_content()
WebDriverWait(driver, 10).until(EC.frame_to_be_available_and_switch_to_it((By.ID,"form_frame")))
