Elements that are not visible on the Web page are not displayed on the page, but exist in the DOM tree, and these elements can be found webdriver.

The element.is_displayed () method can determine whether an element is displayed on the page, or False if the display returns TRUE.

HTML code for testing:

<HTML> <Head> <title>Displaying and hiding elements in HTML</title> <Metahttp-equiv= "Content-type"content= "text/html; charset=utf-8" /><Scripttype= "Text/javascript">     functionShowAndHidden1 () {varDiv1=document.getElementById ("Div1"); varDiv2=document.getElementById ("Div2"); if(Div1.style.display=='Block') Div1.style.display='None'; ElseDiv1.style.display='Block'; if(Div2.style.display=='Block') Div2.style.display='None'; ElseDiv2.style.display='Block'; }     functionShowAndHidden2 () {varDiv3=document.getElementById ("Div3"); vardiv4=document.getElementById ("div4"); if(div3.style.visibility=='Visible') div3.style.visibility='Hidden'; Elsediv3.style.visibility='Visible'; if(div4.style.visibility=='Visible') div4.style.visibility='Hidden'; Elsediv4.style.visibility='Visible'; } </Script> </Head> <Body>     <Div>Display: element does not occupy page position</Div>     <DivID= "Div1"style= "Display:block;">DIV 1</Div>     <DivID= "Div2"style= "Display:none;">DIV 2</Div>     <inputID= "Button1"type= "button"onclick= "showAndHidden1 ();"value= "div Toggle" />     <HR>     <Div>Visibility: element occupies page position</Div>     <DivID= "Div3"style= "visibility:visible;">DIV 3</Div>     <DivID= "Div4"style= "Visibility:hidden;">DIV 4</Div>     <inputID= "Button2"type= "button"onclick= "showAndHidden2 ();"value= "div Toggle" /> </Body> </HTML>
