使用带有selenium

Question

我编写了一个脚本，使用python和selenium从网页中选择某个字段。该页面上有一个下拉列表，我想从中选择“全部”。但是，我尝试了许多不同的方法来制作它但不能。 下面是下拉列表的样子。

下拉列表选择的Html元素：

<select name="ctl00$body$MedicineSummaryControl$cmbPageSelection" onchange="javascript:setTimeout('__doPostBack(\'ctl00$body$MedicineSummaryControl$cmbPageSelection\',\'\')', 0)" id="ctl00_body_MedicineSummaryControl_cmbPageSelection">
        <option selected="selected" value="25">25</option>
        <option value="50">50</option>
        <option value="100">100</option>
        <option value="all">All</option>

    </select>

我试过的脚本：

from selenium import webdriver
import time

driver = webdriver.Chrome()
driver.get('http://apps.tga.gov.au/Prod/devices/daen-entry.aspx')

driver.find_element_by_id('disclaimer-accept').click()
time.sleep(5)
driver.find_element_by_id('medicine-name').send_keys('pump')
time.sleep(8)
driver.find_element_by_id('medicines-header-text').click()
driver.find_element_by_id('submit-button').click()
time.sleep(7)

 #selection for the dropdown should start from here

driver.find_element_by_xpath('//select[@id="ctl00_body_MedicineSummaryControl_cmbPageSelection"]').click()
driver.find_element_by_xpath('//select//option[@value]').send_keys("All")

Answer 1

这对你有用：

#option1
select_obj = Select(driver.find_element_by_xpath('//select[@id="ctl00_body_MedicineSummaryControl_cmbPageSelection"]'))
select_obj.select_by_visible_text('All')
#option2
select_obj = Select(driver.find_element_by_id('ctl00_body_MedicineSummaryControl_cmbPageSelection'))
select_obj.select_by_visible_text('All')

不要忘记使用Select

导入from selenium.webdriver.support.ui import Select

您可以在此处阅读完整文档以查找所有Select方法：https://seleniumhq.github.io/selenium/docs/api/py/webdriver_support/selenium.webdriver.support.select.html

Answer 2

我最初想过建议您尝试从下拉选择之前的元素中进行制表，类似于此代码中的概念：

driver.find_element_by_id('<id of element before the dropdown select>').send_keys(Keys.TAB)
driver.find_element_by_id('//select[@id="ctl00_body_MedicineSummaryControl_cmbPageSelection"]').send_keys('AL')
driver.find_element_by_id('//select[@id="ctl00_body_MedicineSummaryControl_cmbPageSelection"]').send_keys(Keys.ENTER + Keys.TAB)

但是，堆栈跟踪中的错误可能会显示找不到该ID的下拉列表选项。我相信，当您通过使用Selenium IDE中的Record选项记录单击下拉选择并选择选项的操作时，您应该验证您正在使用的id是该元素的正确ID。

最终找到了解决方法。这是我做的：

from selenium import webdriver
import time

driver = webdriver.Chrome()
driver.get('http://apps.tga.gov.au/Prod/devices/daen-entry.aspx')

driver.find_element_by_id('disclaimer-accept').click()
time.sleep(5)
driver.find_element_by_id('medicine-name').send_keys('pump')
time.sleep(8)
driver.find_element_by_id('medicines-header-text').click()
driver.find_element_by_id('submit-button').click()
time.sleep(7)

driver.find_element_by_xpath('//select[@id="ctl00_body_MedicineSummaryControl_cmbPageSelection"]').click()
driver.find_element_by_xpath('.//option[@value="all"]').click()
time.sleep(10)
