An import (Import)
from selenium.webdriver.support.select import Select
Second, choose (select)
Select class provides three methods to select an option:
select_by_index(index)
select_by_value(value)
select_by_visible_text(text)
note:
- index from 0 to start
- value is the value of a property option label, not the value displayed in the drop-down box
- visible_text option tag is in the middle value, the value is displayed in the drop box
Third, anti-election (deselect)
Selectively bound to invert the selection and cancels selection. Select offers four methods to cancel our original choice:
deselect_by_index(index)
deselect_by_value(value)
deselect_by_visible_text(text)
deselect_all()The first three correspond respectively to select, the fourth is the abolition of all options, yes, you're not wrong, it is canceled.
There is a special select tag, i.e. set select multiple = "multiple" attribute, which can be a multi-select box is selected,
By repeatedly select, select a number of options, and by deselect_all () to cancel them all.
Note: the following two, the same intention of
# Return the first or sub-item currently selected
print(Select(driver.find_element_by_xpath("//select[@id='nr']")).first_selected_option.text)
# Currently selected output of the first item, i.e., the second display
now the Select = (driver.find_element_by_css_selector ( "body> form> SELECT")). First_selected_option
Print (now.text)
