在Selenium Python3中切换到第二个iframe

Question

我正在尝试切换到网站的第二个iframe为我的业务个人自动填充器。

以防我可能会被标记为dup，我已经尝试了Python Selenium switch into an iframe within an iframe，但遗憾的是没有得到太多。

下面是两个iframe的html代码。第二个iframe位于第一个iframe中：

<div id="tab2_1" class="cms_tab_content1" style="display: block;">
    <iframe id="the_iframe"src=
"http://www.scourt.go.kr/portal/information/events/search/search.jsp">
</iframe> <!-- allowfullscreen --></div>


<div id="contants">
<iframe frameborder="0" width="100%" height="1100" marginheight="0" 
marginwidth="0" scrolling="auto" title="나의 사건검색" 
src="http://safind.scourt.go.kr/sf/mysafind.jsp
sch_sa_gbn=&amp;sch_bub_nm=&amp;sa_year=&amp;sa_gubun=&amp;sa_serial=&amp;x=&amp;
y=&amp;saveCookie="></iframe>

<noframes title="나의사건검색(새창)">
<a href="http://safind.scourt.go.kr/sf/mysafind.jspsch_sa_gbn
=&amp;sch_bub_nm=&amp;sa_year=&amp;sa_gubun=&amp;sa_serial=&amp;x=&amp;y=&amp;
saveCookie=" target="_blank"
title="나의사건검색(새창)">프레임이 보이지 않을경우 이곳을 클릭해주세요</a></noframes></div>

仅供参考-到目前为止，我尝试了这些：

#METHOD-1
WebDriverWait(driver, 10).until(EC.frame_to_be_available_and_switch_to_it(By.ID,"the_iframe"))
WebDriverWait(driver, 10).until(EC.frame_to_be_available_and_switch_to_it(By.CSS_SELECTOR,"#contants > iframe"))

#METHOD-2
driver.switch_to.frame(driver.find_element_by_xpath('//*[@id="the_iframe"]'))
driver.WAIT
driver.switch_to.frame(driver.find_element_by_css_selector('//*[@id="contants"]/iframe'))
driver.WAIT

#METHOD-3
iframe = driver.find_elements_by_tag_name('iframe')[0]
driver.switch_to.default_content()
driver.switch_to.frame(iframe)
driver.find_elements_by_tag_name('iframe')[0]

ultrawait.until(condition)

不介意缩进错误，复制粘贴的问题。

我想这是来自#Switch iframe，我对此有疑问。

在#Switch iframe之后的那些输入都是有效的。我已经通过在另一个选项卡中打开iframe来测试它们。

Answer 1

您需要单独处理您的框架:当您完成其中一个框架的工作并希望切换到另一个框架时--您需要这样做：

driver.switch_to.default_content()

然后切换到另一个。

切换到帧时最好使用显式等待：

from selenium.webdriver.support import ui
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By


ui.WebDriverWait(driver, 10).until(EC.frame_to_be_available_and_switch_to_it((By.CSS_SELECTOR, "#contants>iframe")))

其中By你可以使用任何定位器。

Answer 2

根据您的html结构，两个iframe是不同的，第二个不在第一个之间。如果html结构是这样的，那么它应该在第一个文件中：

<div>
    <iframe1>
        <iframe2>
        </iframe2>
    </iframe1>
</div>

但是由于您的第一个<div>和第一个<iframe>在启动第二个div和iframe之前就结束了，这意味着这两个iframe是分开的。

因此，根据您的需求，您只需切换到第二个iframe，可以使用：

WebDriverWait(driver, 10).until(EC.frame_to_be_available_and_switch_to_it(By.CSS_SELECTOR,"second iframe css"))

更新答案：

试试下面的代码：

driver.switch_to.frame(driver.find_element_by_xpath('//*[@id="the_iframe"]'))
driver.WAIT
driver.switch_to.frame(driver.find_element_by_xpath('//iframe[contains(@src,'mysafind')]'))
driver.WAIT
