Hello…I am submitting an issue related to DOM management in ionInput.
i want to use the ionInput event to fire at every time entering a input and check with the regular expression to validate input if not valid i want to remove the data.
it was possible in angular with $event.preventDefault() and i also tried $event.stopPropgation();
here is my Code.
html:
<ion-input type=“text” autocapitalize=“on” (ionInput)=“checkIfvalid($event)” clearInput >
type script:
checkIfvalid(event) {
console.log(event.detail.data);
if (/\d/.test(event.detail.data)) {
console.log(‘i am digit’);
event.preventDefault();
event.stopPropagation();
} else {
console.log(‘i am alphabet’);
event.stopPropagation();
event.stopPropagation();
}
}
