Apply inputMask but hide it in input

Question

I am using this plugin InputMask as mask for my input

<input type="text" data-bind="inputMask: { value: hourValue, mask: 'h:s t\\m', jitMasking: true, showMaskOnFocus: false, showMaskOnHover: false, hourFormat: '12', alias: 'datetime'}">

I want to apply this mask to input, but never show it to user. I've added all posible properties that I've found, but still it isn't enough to hide mask at all.

Here is example : https://jsfiddle.net/sg7uvhdz/1/ Problem - when I remove last item in input, I can see first symbol of mask.

Can I hide it for every case?

Thanks.

 $(function() { $("input").inputmask(); })

Answer 1

Your best bet might be to not apply a mask on that input and then attach an event listener on blur which checks if the input is valid by calling isValid

Something like

var isValid = Inputmask.isValid("<input value>", { alias: "h:s t\\m"});

Answer 2

you can achieve the desired using the oncleared method.

$(function(){

    $("input").inputmask({oncleared: function() {

     $("input").val("");

  }});
})

 $(function(){ $("input").inputmask({oncleared: function() { $("input").val(""); }}); })
