I have an input field for a phone number. It's an optional field on the form, but if it's populated it needs to be 10 digits. So, either empty, or 10 digits. How can I accomplish this using parsley.js?
this question is similar to what I'm looking for, but I've tried various combinations and it's not working:
here's my input:
<input type="text" class="form-control form-control-sm m-input phone-num" autocomplete="off" style="display:none;" id="phone-input" name="phone" placeholder="0" data-parsley-trigger="keyup" data-parsley-validation-threshold="1" data-parsley-debounce="500" data-parsley-type="digits">
and this is the parsley initialization (validation is working for other fields on the same form, so I don't think this is the problem):
$('#myForm').parsley({
trigger: 'keyup',
classHandler: function(el){
return el.$element.closest('.form-group');
},
errorClass: 'has-danger',
errorsWrapper: '<div class="form-control-feedback"></div>',
errorTemplate: '<span></span>'
});
Would a custom validation be needed for this? If so, how can I accomplish that?
