Question

我正在使用Webdriver with Python自动化我们的网站。我无法识别并单击“管理”按钮。我试图切换到iFrame并选择按钮。它没有找到按钮我已经与开发人员交谈了，开发人员说它不在iFrame中。 GUI在GWT中完成我只需要编写CSS或XPath，这样我就可以点击按钮了 CSS会更好，因为它比XPath更快。

我尝试过以下XPath： // DIV [@class =＆＃34; GWT-TabLayoutPanelTabs＆＃34;] /格[最后（）]

使用“查找”按钮在Selenium IDE中测试按钮时，它会突出显示按钮的背景颜色。

有人知道CSS或绝对XPath吗？

HTML如下（管理是底部的最后一个div）：

<html style="overflow: hidden;">
<head>
<body style="margin: 0px;">
<iframe id="__gwt_historyFrame" style="position: absolute; width: 0; height: 0; border: 0;" tabindex="-1" src="javascript:''">

</div>
</div>

我的管理员按钮代码：

adminButton = mydriver.find_element_by_xpath('//div[@class="gwt- TabLayoutPanelTabs"]/div[last()]')
adminButton.click()

我也尝试过：

mydriver.find_element_by_xpath('//div[7]/div/div').click()

Answer 1

在找到内部元素之前，您需要逐个找到nested iframes和switch to them ：

driver.switch_to.frame("__gwt_historyFrame")
driver.switch_to.frame("ClearCore")

administration = driver.find_element_by_xpath("//div[. = 'Administration']")
administration.click()

请注意，我正在按文字查找元素，我认为这更“自然”且合乎逻辑。

如果“管理”链接不在iframe内，请省略两个“switch_to”行。

您可能还需要wait for the element to become clickable：

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

administration = WebDriverWait(driver, 10).until(
    EC.element_to_be_clickable((By.XPATH, "//div[. = 'Administration']"))
)
administration.click()

Answer 2

我终于设法解决了我的问题。开发人员说我必须等待页面完全完成加载。当所有元素都显示在屏幕上时，页面仍在加载JavaScript函数我首先尝试time.sleep（30）然后单击按钮。有效。每次等待30秒效率不高。然后我使用了WebDriverWait，这样效率更高。这是我使用的代码：

WebDriverWait(mydriver, 10).until(lambda d: mydriver.find_element_by_xpath("//div[. = 'Administration']").click())

我需要一些帮助来从HTML中使用CSS或Xpath识别按钮
