예시
<!DOCTYPE html> <html> <body> <style> .valid { color: #0B7866; } .invalid { color: #0B6877; } </style> <div id = "result"></div> <script> function check(input) { var out = document.getElementById('result'); if (input.validity) { if (input.validity.valid === true) { out.innerHTML = "<span class='valid'>" + input.id + " valid</span>"; } else { out.innerHTML = "<span class='invalid'>" + input.id + " not valid</span>"; } } console.log(input.checkValidity()); }; </script> <form id = "testform" onsubmit = "return false;"> <label>Minimum: <input oninput = "check(this)" id = "min_input" type = number min=4 /> </label><br> </form> </body> </html>
