<!DOCTYPE html> <html> <body> <form action="/action_page.php"> Name: <input type="text" id="myText" name="fname" autocomplete="on"> <input type="submit"> </form> <p>Click the "Try it" button to set autocomplete in the text field to "off".</p> <p><b>Note:</b> If you are new to the autocomplete attribute, fill in some text in the text field and submit the form, then reload the page, start to fill in the same values in the text field again - and see how autocomplete works. Then, click the "Try it" button to set autocomplete to "off" - if you type something in the text field now, the browser will not suggest values based on values that you have entered before.</p> <button onclick="myFunction()">Try it</button> <p id="demo"></p> <script> function myFunction() { document.getElementById("myText").autocomplete = "off"; document.getElementById("demo").innerHTML = "autocomplete is now ''off''."; } </script> </body> </html>
