Python+selenium Locating hidden elements

the principle of locating hidden features : The page is primarily "display:none" to control the invisible elements. So we need to modify the display's worth of display= "block to implement the element positioning via JavaScript.

HTML code:

"header">    <a href="#"class ="logo"><strong id="Title" style= " Display:none ">AAAA</strong></a>

The core code is as follows :

Driver =Webdriver. Chrome () Driver.maximize_window () Driver.get ('Http://127.0.0.1:5000/HimoMP') JS="document.getElementById (' Title '). style.display= ' Block '" #Writing JS StatementsDriver.execute_script (JS)#Execute JSContentText = driver.find_element_by_id ('Title'). Text#positioning ElementsPrint(ContentText)#Validation ResultsDriver.quit ()

Printing Results :

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')--Find all the Tag_nameselect (SEL). Select_by_value ('Opel')--value= under All tag_nameOpeltime.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"; '-- Find all the Select to cut out what you want, and then re-assign the display to Driver.execute_script (JS)--= 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
