HTMLHelp Forums _ Client-side Scripting _ Go back button on html page

Posted by: rzaruvne Apr 10 2024, 09:04 AM

I want to add a button next to the "Inciar" button so that when the user clicks, it returns to the last div page visited. I've tried but without success, seems to work only to go back to main page content.

CODE

<!DOCTYPE html>
<html lang="en">

<head>
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">

    <style>
        body {
            display: flex;
            justify-content: center;
            align-items: center;
            height: 100vh;
            margin: 0;
        }

        main {
            text-align: center;
        }

        .page {
            display: none;
        }

        .page.active {
            display: block;
        }

        button {
            background-color: #4CAF50; /* Green shade */
            border: none;
            color: white;
            padding: 15px 32px;
            text-align: center;
            text-decoration: none;
            display: inline-block;
            font-size: 16px;
            margin: 4px 2px;
            cursor: pointer;
            border-radius: 8px;
        }

        button:hover {
            background-color: #45a049; /* Darker green shade on hover */
        }
    </style>

            });
        }

I want to add a button next to the "Inciar" button so that when the user clicks, it returns to the last div page visited.

Then the script needs to know the last DIV "page" the user visited, perhaps you could store its ID in a variable.

Or even better, you could make an array of all previously visited page IDs, which is incremented with the latest ID everytime the function is run. Then the user can go back several DIVs.

This "browser history" will of course disappear when the user leaves the pages, unless you store it in a cookie or similar.

<div id="Não Hospitalar"

Note that IDs must not contain whitespace, according to the HTML5 spec.
