如何使用Selenium和Python从下拉菜单中选择一个选项 [英] How to select an option from the dropdown menu using Selenium and Python

问题描述

我正在尝试使用Python中的Selenium获取大都会北部所有车站组合的票价.我想转到他们的票价页面，将车站名称放入选择字段，单击票价按钮，然后将所需的值复制到数据框中.

我尝试了所有可能的选项以从下拉菜单中选择站点，但是当收到错误消息 ElementNotInteractableException 时，任何方法都无效.

我尝试的代码:

  driver = webdriver.Safari()driver.get('http://as0.mta.info/mnr/schedules/sched_form.cfm')选择=选择(driver.find_element_by_id('Vorig_station'))打印([select.options中o的o.text]time.sleep(3)select.select_by_visible_text('ANSONIA')元素= driver.find_element_by_xpath('//* [@ id ="frmindex"]/table [2]/tbody/tr [6]/td/input [2]')element.click()driver.close() 

打印命令显示了这些选项，但我无法选择并进入下一个票价页面.

请帮助！

使用

I am trying to get the fares for all combinations of stations in Metro-North using Selenium in Python. I wanted to go to their fare page, put station names into the select fields, click on the fare button, and then copy the needed values to the dataframe.

I tried all possible options to select stations from the dropdown menu but nothing works as I get the error: ElementNotInteractableException.

The code I tried:

driver = webdriver.Safari()
driver.get('http://as0.mta.info/mnr/schedules/sched_form.cfm')

select = Select(driver.find_element_by_id('Vorig_station'))
print([o.text for o in select.options])
time.sleep(3)
select.select_by_visible_text('ANSONIA')
element = driver.find_element_by_xpath('//*[@id="frmindex"]/table[2]/tbody/tr[6]/td/input[2]')
element.click()
driver.close()

print command shows the options but I cannot choose and go to the next fares page.

Help please!

解决方案

To get the fares for all combinations of stations in Metro-North using Selenium and python selecting the option ANSONIA from the From Staion drop-down-menu you need to induce WebDriverWait for the element_to_be_clickable() and you can use the following Locator Strategies:

• Using CSS_SELECTOR:

  driver.get("http://as0.mta.info/mnr/schedules/sched_form.cfm")
  WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "select#Vorig_station"))).click()
  select = Select(WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "select#Vorig_station"))))
  print([o.text for o in select.options])
  select.select_by_visible_text('ANSONIA')
  WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "input[value='fares']"))).click()
  

• Using XPATH:

  driver.get("http://as0.mta.info/mnr/schedules/sched_form.cfm")
  WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.XPATH, "//select[@id='Vorig_station']"))).click()
  select = Select(WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.XPATH, "//select[@id='Vorig_station']"))))
  print([o.text for o in select.options])
  select.select_by_visible_text('ANSONIA')
  WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.XPATH, "//input[@value='fares']"))).click()
