JScript to see if checkbox is checked

[Deon]

Hi

What is the the corrct syntact to see if a checkbox has been checked.
I have tried a few things.
Stackoverflow suggests this but alert returns not checked in both cases

if (Apperyio("petboarding").checked) {
alert('PB Checked');
}
else {
alert('PB NOT Checked');
}

Thank you

Hello Deon,

Please use a JS code below for that:

preif (Apperyio("petboarding").find("input").is(":checked")) {
alert('PB Checked');
} else {
alert('PB NOT Checked');
}/pre
