如何在HTML上添加页码

Question

How can I add page numbers to a quiz I am making, it needs to all be in the same file though? So, after the first x many questions have been answered, you click next, to go onto the next page after that you go onto the answers? But all in the same code? How can I do this? I've tried looking on various websites to find this but I cannot see how! Thanks, Nick

EDIT: THE NEXT CODE I ADDED WAS:

        function getValue()
            {
                var x=document.getElementById("page_2");
                alert(x.innerHTML);

       </script>

Answer 1

Use specific <div> with id for every part & hide all other <div> except first part using css. Then use javascript function for showing every part sequentially. When showing 2nd part hide all other part using getElementById , do it all other part & store your result in a static variable, increase it in every part sequentially, hope it will work. check this code -

 <!DOCTYPE html> <html> <head> <title>TODO supply a title</title> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <style> #test2{display:none;} #test3{display:none;} </style> <script> function test1(){ document.getElementById('test2').style.display = 'block'; document.getElementById('test1').style.display = 'none'; } </script> </head> <body> <div id="test1" onclick='test1();'>testing1</div> <div id="test2">testing2</div> <div id="test3">testing3</div> </html>
