The read-only property ValidityState.badInput
indicates if the user has provided input that the browser is unable to convert. For example, if you have a mail input element whose content does not have a '@'
.
Example
<input type="mail" id="email">
var input = document.getElementById("email"); if (input.validity.badInput) { console.log("Bad input detected…"); } else { console.log("Content of input ok."); }
