Hi 

Can we restrict user to enter more than 40 characters to a prompt pop up ?

That pop up show up when user clicks on a button on the form and enter input there, but we want user should not able enter more than 40 characters to the pop up.

How to do that?

Is this sample code helpful?

 

(function executeRule(current, previous /*null when async*/) {
    // Get the field element from the pop-up
    var inputField = g_form.getControl('your_input_field_name'); // Replace with your field name
    
    // Add an event listener to the input field to restrict characters
    inputField.addEventListener('input', function(e) {
        var maxLength = 40;
        if (e.target.value.length > maxLength) {
            e.target.value = e.target.value.substring(0, maxLength);
            // Optionally, display a message to the user
            alert('You cannot enter more than 40 characters.');
        }
    });
})(current, previous);
