Selenium-webdriver (Python) (10) How to handle a drop-down box

This section focuses on

Handling drop-down boxes

Switch_to_alert ()

Accept ()

The dropdown box is one of our most common page elements, for the general element, we only need to position one at a time, but the contents of the drop-down box needs to be positioned two times, first navigate to the dropdown box, and then navigate to the dropdown box inside the options.

Drop_down.html

Save the above code in HTML browser open you will see one of the simplest and most common drop-down boxes, the drop-down list has several options.
Now let's choose the $10.69 in the dropdown list.
#-*-coding=utf-8 from    Selenium import webdriver    import os,time    driver= webdriver. Firefox ()    file_path =  ' file:///' + os.path.abspath (' drop_down.html ')    driver.get (File_path)    Time.sleep (2)    m=driver.find_element_by_id ("ShippingMethod")    M.find_element_by_xpath ("//option[@value = ' 10.69 ']). Click ()    time.sleep (3)    driver.quit ()
Analytical:
This may be different from the previous operation, first to navigate to the elements of the drop-down box, and then select the options in the drop-down list to click on the action.

m=driver.find_element_by_id ("ShippingMethod")
M.find_element_by_xpath ("//option[@value = ' 10.69 ']"). Click ()
Baidu Search Settings Dropdown box operation
#-*-coding=utf-8 from    Selenium import webdriver    import os,time    driver= webdriver. Firefox ()    driver.get ("http://www.baidu.com")        #进入搜索设置页    driver.find_element_by_link_text ("Search Settings"). Click ()        #设置每页搜索结果为100条    m=driver.find_element_by_name ("NR")    M.find_element_by_xpath ("//option[@ Value= '). Click ()    time.sleep (2)        #保存设置的信息    driver.find_element_by_xpath ("//input[@value = ' Save Settings ']. Click ()    time.sleep (2)    Driver.switch_to_alert (). Accept ()            #跳转到百度首页后, search table (100 results on a page)    driver.find_element_by_id ("kw"). Send_keys ("Selenium")    driver.find_element_by_id ("su"). Click ()    Time.sleep (3)    driver.quit ()
Analytical:
When we save Baidu's settings will pop up a OK button; We did not follow the usual method to locate the "OK" button on the pop-up window, but instead use:
Driver.switch_to_alert (). Accept ()
This is done because the window comparison is a unique warning message, so it can be handled in such a simple way.
–switch_to_alert ()
A warning that focuses on the page (hint)
–accept ()
Accept warning Prompts
