我的测试在 chromedriver 和 IEServerDriver 上运行良好。但它不适用于 Safari10 (/usr/bin/safaridriver) 附带的 safaridriver。在 SafariDriver 上，它可以找到第一级和第二级 iframe。但是虽然它在那里，但它找不到第 3 级 iframe。请在下面的终端中找到 HTML、代码和输出。

平台：macOS Sierra 版本 10.12 / Safari 版本 10.0 (12602.1.50.0.10) / Python 2.7.12 / selenium 3.0.1

HTML：

<body style="background: black;">
<!-- Technical Info -->
<!-- Some Info -->
<iframe name="AppFrame" src="path-to-an-app" seamless="" height="100%" width="100%" frameborder="0">
    <html><head></head>
    <body>
    <iframe id="contentframe" name="internal" class="contentFrame" iframeid="fp1478845052175">
        <html><head></head>
        <body>
        <!-- Technical Info -->
        <!-- Some Info of inner app -->
            <iframe name="AppFrame" src="path-to-another-app" seamless="" height="100%" width="100%" frameborder="0"></iframe>
            ...
    </iframe>

代码：

driver.switch_to_frame(driver.find_element_by_name("AppFrame"))
print("Switch to 1st iframe")
time.sleep(1)
driver.switch_to_frame(driver.find_element_by_id("contentframe"))
print("Switch to 2nd iframe")
time.sleep(1)

print("body: " + driver.find_element_by_tag_name("body").get_attribute("outerHTML"))
try:
    appframe = driver.find_element_by_name("AppFrame")
except:
    print("body in except: " + driver.find_element_by_tag_name("body").get_attribute("outerHTML"))

driver.switch_to_frame(driver.find_element_by_name("AppFrame"))
print("Switch to 3rd iframe")
print("body again: " + driver.find_element_by_tag_name("body").get_attribute("outerHTML"))

输出：

Switch to 1st iframe
Switch to 2nd iframe
body: <body>
<!-- Technical Info -->
<!-- Some Info -->
<iframe name="AppFrame" src="path-to-another-app" seamless="" height="100%" width="100%" frameborder="0"></iframe>
</body>

body in except: <body>
<!-- Technical Info -->
<!-- Some Info -->
<iframe name="AppFrame" src="path-to-another-app" seamless="" height="100%" width="100%" frameborder="0"></iframe>
</body>

我已经在 C# 上尝试过，它可以找到 iframe，但我无法切换到它并收到错误消息“stale element”，尽管我可以访问它的属性，例如outerHTML、位置、src、宽度。
