Selenium webdriver--manipulating hidden elements

Sometimes we encounter elements that are not visible, and selenium cannot manipulate these elements at this time. For example, the following scenario:

Page mainly through "Display:none" to control the entire drop-down box is not visible. This time if you directly manipulate this drop-down box, you will be prompted:

 fromSeleniumImportWebdriver fromSelenium.webdriver.support.selectImportSelectImportOs,timedriver=Webdriver. Chrome () File_path='file:///'+ Os.path.abspath ('test.html') Driver.get (file_path) Sel= Driver.find_element_by_tag_name ('Select') Select (SEL). Select_by_value ('Opel') Time.sleep (2) Driver.quit ()

Exceptions. ElementNotVisibleException:Message:element not visible:element isn't currently visible and may isn't manipulated

We need to modify the display value through JavaScript.

' document.queryselectorall ("select") [0].style.display= "block"; '  = driver.find_element_by_tag_name ('select') Select (SEL). Select_by_value ('Opel')

Document.queryselectorall ("select") [0].style.display= "block";

Document.queryselectorall ("select") selects all of the Select.

[0] Specify the first of the set of labels.

style.display= "Block"; Modify the style of the display= "block" to indicate that it is visible.

After the execution of this JS code, you can normally operate the drop-down box.
