How to get the jQuery MaskedInput unmask() functio

问题:

I am trying to have one input on my page that I would like to have a U.S. phone number mask by default. If a end user clicks a checkbox specifing they would like to enter a International phone number I want the mask to be removed.

I have tried multiple ways and have been unsuccessful thus far. In the current project I am using jQuery to hide/show a completely different input. But I don't like that option and would like a more streamlined approach.

I am using the following:

jQuery 1.4.1 (going to upgrade to 1.4.2 soon) and jQuery.MaskedInput-1.2.2

<script type="text/javascript">
$(document).ready(function($) {
  if ($("#InternationalOfficePhone").attr('checked') == false) {
    $("#OfficePhone").mask("[phone]? x99999");
  }
});

$("#InternationalOfficePhone").click(function() {
  if ($("#InternationalOfficePhone").attr('checked') == true) {
    //$("#OfficePhone").mask(); //doesn't work
    //$("#OfficePhone").unmask(); //doesn't work
    $("#OfficePhone").unmask("[phone]? x99999"); //doesn't work
  } else {
    $("#OfficePhone").mask("[phone]? x99999");
  }
});
</script>

The code above works properly to set the default mask, but no matter what I try on the click event for the InternationalOfficePhone it doesn't remove the mask.

Any help is much appreciated.

You don't need to pass a parameter to the unmask function! Use it without a parameter and it works well.

$("#OfficePhone").unmask();

I was able to figure out the code to get it to work. Below is the code I am using now.

<script type="text/javascript">
$(function($) {
  $("#OfficePhone").mask("[phone]? x99999");
  $("#InternationalOfficePhone").click(function() {
    var mask = "[phone]? x99999";
    if ($("#InternationalOfficePhone").is(':checked')) {
      $("#OfficePhone").unmask(mask);
    } else {
      $("#OfficePhone").mask(mask);
    }
  });
});
</script>

I run through the same problem, and what helped me is:

    var maskedInput = $("#id").data('mask');
    if (maskedInput) {
        maskedInput.remove();
    }

回答4:

Try using the :checked instead of attr check, I think that is the problem. I mean use $('#InternationalOfficePhone').is(':checked') in the if condition.

回答5:

Remove the inputmask:

$(selector).inputmask('remove');

or

var input = document.getElementById(selector);
if (input.inputmask)
  input.inputmask.remove()

or

Inputmask.remove(document.getElementById(selector));

I am using query.maskedinput.js Version: 1.4.1 I referred https://github.com/digitalBush/jquery.maskedinput/blob/bb66bf9b1c3eddd1d2349cee103127ae08d0a877/demo/index.html

the unmasking is done by $("input").blur(function() { $("#info").html("Unmasked value: " + $(this).mask());

example Masking is

$("#pannumber").mask("aaaaa 9999 a");

Unmasking

$("#pannumber").blur(function() {

var pannumber= $(this).mask() ;
