使用 Selenium 从另一个框架中查找与下拉列表相关的元素 -- Python

Question

我一直在尝试编写一个程序来自动化我的工作。我的任务有一系列步骤，但我卡在了一点。我不断收到 NoSuchElementException。我尝试使用 id、class、Selenium 的名称方法，但似乎没有任何效果。我现在的代码是这样的：

from selenium import webdriver
from selenium.webdriver.common.by import By

browser = webdriver.Chrome('C:\Users\abc\AppData\Local\Programs\Python\Python36\chromedriver.exe')
browser.get("http://example.com/login.aspx")

usernameElem = browser.find_element_by_id('txtuser')
usernameElem.send_keys('admin')

passwordElem = browser.find_element_by_id('txtpassword')
passwordElem.send_keys('password')

loginElem = browser.find_element_by_id('btn_login')
loginElem.click() # follows the "Read It Online" link

browser.get("http://example.com/Reports.aspx")

subscriberslistElem = browser.find_element_by_id('ContentPlaceHolder1_rptDC_lnk_0')
subscriberslistElem.click()

browser.implicitly_wait(3)
entityElem = browser.find_element_by_id("report_Entity_ClientState")
print("Test")
entityElem.send_keys('Entity1')

browser.implicitly_wait(3)
reportElem = browser.find_element_by_class_name('selectbox')
print("Test 2")
reportElem.click()

showdataElem = browser.find_element_by_id('btn_new')
showdataElem.click()

excelElem = browser.find_element_by_id('imgExport')
excelElem.click()
print('All is well')

Link to webpage, complete files.

奇怪的是，当我以代码形式在线打开HTML文件并搜索'report_Entity_ClientState'时，没有任何结果。我尝试访问的元素图像：

First element.

Second element.

找不到实体和报表元素。以下部分代码 return 错误。

entityElem = browser.find_element_by_id("report_Entity_ClientState")
reportElem = browser.find_element_by_class_name('selectbox')
entityElem.send_keys('Entity1')
browser.implicitly_wait(3)

Answer 1

如果您查看 <input id="report_Entity_ClientState" ... > 节点，则该类型是隐藏的。所以我们必须先取消隐藏 WebElement 并按如下方式发送字符：

entityElem = browser.find_element_by_xpath("//input[@id='report_Entity_ClientState']")
browser.execute_script("arguments[0].removeAttribute('type')", entityElem);
entityElem.send_keys('Entity1')

Answer 2

browser.switch_to.frame("ContentPlaceHolder1_myIframe")

我不得不在尝试查找元素之前添加这一行。现在@DebanjanB 和@Ratmir Asanov 提到的所有方法都可以完美运行。感谢您一直以来的支持。
